Hi,

I have an installer script that contains lots of little functions. It
has an interactive menu and the corresponding function is called. Over
time it grew long and when I want to add a new function, I should give
a unique name to that function. However, Python allows the
redefinition of functions:

#!/usr/bin/env python

def step_1():
    print 1

def step_1():
    print 2

step_1()

This will call the 2nd function. Now my functions are called step_ID
(like step_27(), step_28(), etc.). How to avoid the danger of
redefinition? Now, when I write a new function, I search for its name
to see if it's unique but there must be a better way.

Thanks,

Laszlo
P.S.: the script is here ( https://github.com/jabbalaci/jabbatron ) if
you are interested. It's made for Ubuntu.
