On the net, you can work with easy date and time with the datetime class. You can use the methods as convert.todateTime (string), datetime.parse () and datetime.parseexact () METWORK to convert a date-base string to a system.datetime object.convert.todateTime (string) METHOD converts the specified chain representation from a date and time of

a date and time equivalent value C rope # idate = "2005/05/05"; Datetime odte = convert.todatetime (IDATE); Messagebox.show (ODATE.DAY + "" + ODATE.MONTH + "" + ODATE.YEAR); dim idate the string = "2005/05/05" Dim Oide as datetime = convert.todatetime msgbox (idate.day & "" & odte.month & "" datetime.parse ( )

DATETIME.PARSE METHER supports many formats. It is very indulgent in terms of syntax and will analyze dates in many different formats. This means that, this all can analyze only ropes that consist exactly of a date / time presentation, can not look at the date / time between text. C # idate string = "2005-05-05"; Datetime odte = datetime.parse

(idate); Messagebox.show (ODATE.DAY + "" + ODATE.MONTH + "" + ODATE.YEAR); dim idate the string = "2005/05/05" Dim Oide as datetime = datetime.parse msgBox (ODATE.DAY & "" & ODATE.YEAR) DATETIME.PARSEEXACT ( ) Parseexact will allow you to specify the exact format of your date chain for use for the analysis. It's good to

use this case string is always in the same format. The format of the chain representation must match the specified format exactly. C # ISTRING = "2005-05-05 22:12 PM"; Datetime odate = datetime.parsexact (istering, "aaaa-mm-dd hh: mm tt", null); Messagebox.show (ODATE.TRING ()); DIM ISSRING AS STRING = "2005-05-05 22:12 PM"

Dim Oate as datetime = datetime.parsexact (iString, "AAAA-MM-DD HH: MM TT", Nothing) MsgBox (ODATE.Thring ( )) The null parameter (nothing) is the culture object that corresponds to the current culture is used. CultureInfo when numbers, dates and hours are formatted on ropes or analyzed from ropes, then a culture (cultureinfo) is used to

determine how this is done. If you know what the specific culture that dates and decimal values ?or currency will be in front of the time, you can use this specific CultureInfo property, for example, CultureInfo ("en-US"). CultureInfo.invarianture property is neither a neutral nor a specific culture. It is a third type of culture that is culture differentiation.

It is associated with the English language, but not with a country or region. C # ISTRING = "2005-05-05 22:12 PM"; Datetime odte = datetime.parsexact (ystring, "aaaa-mm-dd hh: mm tt", system.globalization.cultureinfo.invariantculture); Messagebox.show (ODATE.TRING ()); DIM ISSRING AS STRING = "2005-05-05 22:12 PM" Dim Oate as

datetime = datetime.parsexact (ystring, "aaaa-mm-dd hh: mm tt", system.globalization.cultureinfo.invariantculture) MSGBox (ODATE.TOTRING ()) DATETIME.TRYPARSE DATETIME.TRYPARSE Converts the specified sequence representation of a date and time of your equivalent datetime using the specified culture specific format information and

Style formatting, and returns a value that indicates whether the conversion has managed. BOOL PUBLIC STATIC TRYPARSE (String S, Outside DateTime) This all is similar to datetime.Parse (string), except that Tryparse (string, datetime) does not throw a destray If the conversion fails. In addition, this method tries to ignore not recognized data, if

possible, and fills, day, and the year information with the current date missing. The ThreeParse is dependent on the culture that must be very careful if you decide to use it.

DatetimePicker next ..... ComboBox Text and value One of the many common problems we face in software development is dealing with dates and horms. After

obtaining a date string against an API, for example, we need to convert it into a human qualificant format. Once again, if the same API is used in different seals, the conversion will be different. A good date and time library should convert time according to the time zone. This is just one of the many nuances that need to be manipulated when dealing

with dates and time. Fortunately, Python comes with the built-in datetime module to deal with dates and horms. As you probably guessed, comes with several functions to manipulate dates and times. Using this module, we can easily analyze any date and conversion string for a datetime object. The datetime module consists of three different types of

objects: date, time and date and date. Obviously, the data object holds the date, the time holds the time and the datetime has date and time. For example, the following code will print the current date and time: Import DateTime Printing ('Current Date / Time: {} format (datetime.datetime.now ())) Perform this code will print something similar to this :

python3 datatime-print-1py Date / Time: 2018-06-29 08: 15: 27.243860 When no custom format is given, the standard string format is used, that is, the format for "2018-06-29 08:15: 27.243860" is in ISO 8601 format (yyyy-mm-ddth: mm: ss.mmmmmm). If our input string to create a datetime object is in the same ISO 8601 format, we can easily

analyze it to a datetime object. Let's take a look at the code below: Import datetime date_time_tr = '2018-06-29 08: 15: 27.243860' date_time_obj = datetime.datetime.strptime (Data_time_str, '% y-% m-% d% h:% M:% S.% f ') Print (' date: ', date_time_obj.date ()) Print (' Time: ', Data_time_obj.time ()) Print (' date time: ', Data_Time_Obj) Running the

date, time and time : Python3 datetime-print-2.py Date: 2018-06-29 Time: 08: 15: 27.243860 Date Time: 2018-06-29 08: 15: 27.243860 In this example, we are using a new method called Strptime. This method takes two The first is the string representation of the date and the second is the format of the entry string. Specifying the format as this makes

the analysis much more fast, since the datetime does not need accurate Try to interpret the format on the own account, which is much more expensive computationally. The return value is the date and time type. In our example, "2018/06/29 08: 15: 27,243860" is the input chain and "% y-% m-% d% h:% M:% S.% F" is the format of our date sequence.

The datetime return value is stored in variable date_time_obj. As this is a date and time object, we can call the same directly on it date () and time (). As you can see from the skirt, it prints the 'meeting' and part 'time' from the input chain. You may be wondering which is the meaning of the format "% y-% m-% d% h:% m:% s.% f". These are known as

format signals. Each symbol represents a different part of the date-time, such as day, month, year, etc. Check the Strptime documentation to the list of all different types of format code supported in Python. For a quick reference, here is what we are using in the above code:% Y: Year (4 Dogs)% M: M??s% D: MONTH DAY% H: Hours (24 hours)% M:%

s minutes : Seconds% F: Microseconds All these symbols except the year, are expected to be with zeros on the left. So if the format of a string is known, it can be easily analyzed in a datetime object using streptime. Let me show you a more non-trivial example: Import datetime date_time_str = '28 June 2018 07:40 'date_time_obj =

datetime.datetime.strptime (date_time_str,'% b% d% y% i:% M% p ') print (' date: ', date_time_obj.date ()) print (' time: ', date_time_obj.time ()) print (' date-time: ', date_time_obj) since the following result you can see that The chain was analyzed with only one time it is being duly printed by the datetime object here: python3 datetime-print-3.py Date:

2018/06/28 Time: 07:40:00 Date-Time: 2018/06 / 28 07:40:00 Here are a few more examples of time formats normally used and the signs used ? € ? € ? € "% b % d% y in% i:% m% p "" September 18, 2017, 22: 19:55 "->"% b% d,% y,% h:% m:% s "Sun, 12 / 05/99.12: 30 "->"% A,% d /% m /% y,% I:% M% p "" sec, 21 March, 2015 "->"% A,% D% B,% y ""

2018-03-12T10: 12: 45Z "->"% y% m-% dt% h:% M:% sz "You can analyze a date and time sequence of any format using the table mentioned in the Strptime documentation. Date manipulation times becomes more complex when dealing with horizean spindles. All the above examples that we discuss are naive date and time objects, this is, these objects

do not contain any data spindle-related data. The datetime object does have a variable that contains the information of the time spindle, Tzinfo. Import DateTime as DT DTIME = DT.DATETIME.NOW () Printing (dtime.tzinfo) Printion (dtime.tzinfo) This code will be printed: python3 datetime-tzinfo-1.py 2018/06/29 22: 16 : 36,132767 No Tzinfo Sa¨²da is

none as it is an ingenious datetime object. For conversion time spindle, a library called Pytz is available for Python. You can install it as described in these instructions. Now, let's use the Pytz library to convert Timestamp above to UTC. Datetime Import as DT Printing Pytz DTIME = DT.DATETIME.NOW (PYTZ.UTC) Print (dtime.tzinfo) Sa¨²da: Python3

datetime-tzinfo-2.py 2018 06/29 17: 08: 00.586525 + 00: 00 UTC +00: 00 is the difference between the displayed time and the UTC time. In this example the value of Tzinfo becomes UTC as well as, therefore, at 0:00 offset. In this case, the date and time object is a horace-aware zone object. Likewise, we can convert the date and time chains to any

other time zone. For example, we can convert the string "2018/06/29 17: 08: 00.586525 + 00: 00" to "amerry / new_york" time spindle, as shown below: import datetime as dt date_time_str impority Pytz = '2018/06/29 17:08:00' date_time_obj = dt.datetime.strptime (date_time_str, '% y% m-% d% h:% m:% s') pipe pytz.timezone ('AM? ? rica /

new_york') = timezone_date_time_obj) print (timezone_date_time_obj.tzInfo) Sa¨²da: Python3 datetime-tzinfo-3.py 2018/06/29 17: 08: 00-04: 00 america / new_york first, nos We convert the string to a date and time object, date_time_obj. Then, converted it to a timezone_date_time_obj datetime object, allowed-time spindle. Once you have defined the

time zone as as Sa¨²da time shows that it is 4 hours behind that UTC time. You can check this page Wikipedia to find the complete list of available horizean spindles. Converting Timezones We can convert time zone from a date and time object from one region to another, as shown in the example below: Import datetime as DT imports pytz timezone_nw

= pytz.timezone ('AM? ? Rica / New_york ') nw_datetime_obj = dt.datetime.now (timezone_nw) timezone_london = pytz.timezone (' europe / london ') london_datetime_obj = nw_datetime_obj.astimezone (timezone_london) Print (' America / New_York: ', NW_DATETIME_OBJ) Print (' Europe / London : ', London_Datetime_Obj) First, we create a

datetime object with the current time and set it as the "AM? ? rica / new_ork" time spindle. Then using the ASTIMEZONE () method, we convert this date and time to "/ Europe London" time spindle. Both datetimes will print different values ?such as: python3 datetime-tzinfo-4.py america / new_york: 2018/06/29 22: 21: 41.349491-04: 00 Europe /

London: 2018/06/30 03: 21: 41, 349491 + 01: 00 Check out Our hands-on, a practical guide to learn git, with the best practices, patterns accepted by Ind¨²stria, and included fraud sheet. Commands Stop Googling Git and Really Learn! As expected, the time-time are different since they are about 5 hours of interval. Using third python libraries is

modular datetime can convert all different strings types to a date and time object. But the main problem is that in order to do this you need to create the appropriate code formatting chain that Strptime can understand. Creating this chain takes time and makes the cordo more difficult to read. Instead, we can use other third-party libraries to make it

easier. In some cases, these third-party libraries are also improved built-in support for manipulating and comparing time from time, and some built-in haven zones, so you do not need to include an extra package. Let's take a look at some of these libraries in the following sections. The dateutil module is an extension for the datetime module. An

advantage is that you do not need to pass any analysis code to analyze a string. For example: Dateutil.Perser import Parse datetime = parse ('2018/06/29 22:21:41') Print (date and time) This analysis function will analyze the Chain automatically and store it in the date and time variable. Analysis is done automatically. You do not have to mention any

format chain. Let's try to analyze different types of strings using dateutil: from dateutil.parser import parse date_array = ['2018/06/29 08: 15: 27,243860', '28 June 2018 07:40 ',' 28 2018 Jun for 07:40 ', '18 September 2017, 22:19:55', 'Sun, 1999/05/12, 12:30', 'Mon, March 21, 2015', '2018 -03-12t10: 12: 45z ',' 2018/06/29 17: 08: 00.586525 + 00: 00 ','

2018/06/29 17: 08: 00.586525 + 05: 00 '' Tuesday, September 6 , 2017 at 4:30 hours'] for date on date_array: print ('analysis:' + date) dt = parse (date) print (dt.date ()) print (dt.time ()) print (dt.tzinfo) print ('') Sa¨²da: Python3 dateutil-1 .py Analysis: 2018/06/29 08: 15: 27,243860 2018/06/29 08: 15: 27,243860 None of dwarf Lise: 28 Jun 2018 07:40

2018/06/28 7:40:00 none of the analysis: June 28, 2018 at 07:40 2018/06/28 07:40:00 no analysis: september 18 , 2017, 22:19:55 2017/09/18 22:19:55 No analysis: Sun, 1999/05/12, 12:30 1999/05/12 00:30:00 No Analysis: Mon , March 21, 2015 2015/03/21 00:00: 00 No Analysis: 2018-03-12T10: 12: 45z 2018/03/12 10:12: 45 TZUTC () Analysis of:

2018/06/29 17: 08: 00586525 + 00: 00 2018 / 6/29 17: 08: 00586525 tzutc () Analyzing: 2018/06/29 17: 08: 00586525 + 05: 00 2018/6/29 17: 08: 00,586525 tzoffset (none, 18000) Analysis: September 6, 2017 to 4:30 hours 2017/09/06 16:30:00 No you can see that almost any type of rope can be analyzed easily using the dateutil module. About that

convenient, remember earlier than having to predict the format makes the code much slower, so if you are a code requires high performance, then this may not be the right approach for your application ? o. Maya Maya also makes it easy to analyze a sequence and to change horizean spindles. Some simple examples are shown here: Import Maya DT

= = Print (dt.date ()) Print (dt.tzinfo) Sa¨²da: Python3 Maya-1.py 2018-04-29 17:45:25 UTC to convert the time to a different time: Import Maya DT = Maya.Parse ('2018-04-29t17: 45: 25z'). DateTime (to_timezone = 'america / new_york', ingenua = false) Print (dt.date ()) Print (dt.timo ()) Print (dt.tzinfo) Sa¨²da: Python3 Maya-2.py 2018-04-29 13 : 45:

25 AMERICA / NEW_YORK NOW IS NOT EACCIL TO USE? Let's try Maya with the same set of strings we use with date: Import Maya Data_array = ['2018-06-29 08: 15: 27.243860', '28 Jun 2018 7:40 ',' 23 June 2018 7: 40AM ',' September 18, 2017, 22:19:55 ',' Sun, 05/12/1999, 12:30 ',' Mon, March 21, 2015 ',' 2018-03-12T10 : 12: 45z '' 2018-06-29

2018-06-29 17: 08: 00.586525 UTC Analysis: 2018-06-29 17: 08: 00.586525 + 05: 00 2018-06-29 12: 08 : 00.586525 + 00: 00: 00 2018-06-29 12:08: 00.586525 Analising UTC: Tuesday, September 6, 2017 to S 16:30 2017-09-06 16: 30: 00 + 00: 00 2017 -09-06 16:30:00 UTC As you can see, all date formats were analyzed analyzed. But did you notice

the difference? If we are not providing the hourly spindle information, it automatically converts you to UTC. So it is important to note that we must provide the null and ingenuous parameters if the time is not in the UTC. Arrow arrow is another library to deal with the datetime in Python. And as before with Maya, he also reaches the datetime format

automatically. Once interpreted, it returns a Python datetime object from the arrow object. Let's try this with the same example string that we use for Maya: Import arrow dt = arrow.get ('2018-04-29T17: 45: 25z') Print (dt.date ()) Print (dt.time ()) Print (dt.tzinfo) Sa¨²da: Python3 arrow-1.py 2018-04-29 17:45:25 Tzutc () and here is how you can use

the arrow to convert horazones using the whole: import arrow dt = arrow.get ('2018-04-29t17: 45: 25z'). (DT) Print (DT.Date ()) Print (dt.time ()) Sa¨²da: Python3 arrow-2.py 2018-04-29T13: 45: 25- 04:00 2018-04-29 13:45:25 As you can see the date time chain is converted to the "AM? ? rica / new_york" regiment. Now let's use the same set of strings

that We used: Import arrow Data_array = ['2018-06-29 08: 15: 27.243860', '2018-03-12T10: 12: 45z', '2018-06-29 17: 08: 00.586525 + 00: 00', '2018-06-29 17: 08: 00.586525 + 05: 00',] for date in date_array: dt = arrow.get (date) Print ('analyzing:' + date) Print (DT) Print (DT.DATE (DT) )) Print (dt.time ()) Print (dt.tzInfo) This code will fail for the

date time strings that have been commented on, which is more than half of our examples. The exit for other strings will be: python3 arrow-3.py analting: 2018-06-29 08: 15: 27.243860: 15: 27.243860 + 00: 00 2018-06-29 08: 15: 27.243860 tzutc () parsing: 2018-03-12T10: 12: 45Z- 12Q10: 12: 45 + 00: 00 201 8-03-12 Tzutc () Analyzing: 2018-06-29

17:08: 00.586525 + 00: 00 2018-06-29T17: 08: 00.586525 + 00: 00 2018-06-29 17: 08: 00.586525 tzoffset (none, 0) parsing: 2018-06-29 17: 08: 00.586525 + 05: 00 2018-06-29t17: 08: 00.586525 + 05: 00 2018-06-29 17: 08: 00.586525 tzoffset (none, 18000) to properly analyze the date chains date I commented, I commented, Must pass the

corresponding format tokens to give ? s library clues about how analis?? it. For example, "mmm" for one month name, such as "Jan, February, sea," etc. You can check this guide to all dispon?veis tokens. Conclus? ? o In this article, we show different ways to analyze a string to a DateTime object into Python. You can opt for ? Padra library Python's
