Problem

Is there any possibility that I do not have to type in these very long Python commands?

Solution

Yes, there is command line completion available for Python. Just do this:

import rlcompleter
import readline
readline.parse_and_bind("tab: complete")

You can even point the environment variable $PYTHONSTARTUP to a file, e.g. ~/.pythonrc and put the above lines in it. Then after every start of python, you will have the nice completion feature enabled.
