Python scripting
Naming
It is not necessary to call a script run from the command-line with the '.py' extension. Actually it might be better to hide the implementation (that it is written in python) from the user (for some operating systems).

Python scripting
Header in Linux-like environment
The hash-bang at the top
#!/usr/bin/python enabling you to run the script like (after setting of the ecexcution bit with chmod a+x myscript):
$ myscript rather than
$ python myscript

#!/usr/bin/env python
