So I created a couple of modules: module1.py and module2.py and they're both working fine.

But now I would like to call them from the command line using a script by specifying a corresponding option. For example: 

python launchscript.py -l somefile.txt

Or 

python launchscript.py -x

First option should sent the parameter and execute main() from module1.py and second option should execute main() from module2.py

This launch script should be extensible as I add more internal modules and it should offer built-in command line help.

I'm a python beginner, any help would be appreciated

You have tagged this argparse - have you tried actually using that library? What exactly is your question? – jonrsharpe Nov 20 '14 at 11:27
    
Correct. I tried to use argparse but to no avail, I'm still lost, so I decided to specify the whole requirement. So taking that into account my question would be how to implement a command line shell from Python? – yllanos Nov 20 '14 at 11:55

Then your question is too broad for SO - this isn't a code-writing or tutorial service. However, if you provided a minimal example of your attempted code and a precise problem description (error traceback, inputs and expected and actual outputs, etc.) that would be on-topic. – jonrsharpe Nov 20 '14 at 11:59
