>Try running a 6 month old Python project that you haven't touched and see if it still runs.

My experience has been 6 month of python works fine. In fact, python is my go to these days for anything longer than a 5 line shell script (mostly because argparse is builtin now). On the other hand, running a newly written python script with a 6 month old version of python, that's likely to get you into trouble.

argparse? docopt or google-python-fire

argparse, because argparse is built in. I'm usually writing shell scripts to automate some process for myself and my co-workers. The last thing I want is for them to have to be fiddling with installing external requirements if I can avoid it.
