argparse Python modules in cli

Question

I am trying to run a python script from the Linux SSH Secure Shell command line environment, and I am trying to import the argparse library, but it gives the error: "ImportError: No module named argparse".

I think that this is because the Python environment that the Linux shell is using does not have the argparse library in it, and I think I can fix it fix it if I can find the directories for the libraries being used by the Python environment, and copy the argparse library into it, but I can not find where that directory is located.

I would appreciate any help on finding this directory (I suppose I could include the argparse library in the same directory as my python script for now, but I would much rather have the argparse library in the place where the other Python libraries are, as it should be).

The argparse module was added in Python 2.7. http://docs.python.org/library/argparse.html

Prior to 2.7, the most common way to handle command-line arguments was probably getopt. http://docs.python.org/library/getopt.html

Of course you can always handle the command-line manually simply by looking at sys.argv. However getopt is a good abstraction layer, and argparse is even better.

If you truly need argparse in older environments (debatable), there is a Google Code project maintaining it, and you can include that in your project. http://code.google.com/p/argparse/
