Question

I have written a script which in turn runs some other code and I need to check some conditions in latter code before it gets executed! So i thought of using command line arguments and I don’t have better knowledge on OOP concepts to write classes which was recommended in most of the answers given for similar questions in stack overflow.
can I pass arguments like this

subprocess.call([sys.executable, 'Cnt1', 'argument1', 'argument2'])

If I can, how to read the arguments in the latter code?
I tried to print

print sys.executable
print Cnt1

its showing error for print Cnt1

You can indeed run python using the subprocess module, and pass arguments to that. In essence you’d be running a completely new program; this is not the same as calling a function. Usually there is no need to go to such drastic lengths though.

If you do run a separate python script, you need to parse the arguments passed from sys.argv. The argparse module makes that easier but is not required if all you do is pass a list of arguments.

import sys
print sys.argv
