How do I add tab completion to the Python shell?

I may have found a way to do it.

Create a file .pythonrc

# ~/.pythonrc
# enable syntax completion
try:
    import readline
except ImportError:
    print("Module readline not available.")
else:
    import rlcompleter
    readline.parse_and_bind("tab: complete")

then in your .bashrc file, add

export PYTHONSTARTUP=~/.pythonrc

That seems to work.
