How can you dynamically create variables in Python via a while loop?

Unless there is an overwhelming need to create a mess of variable names, I would just use a dictionary, where you can dynamically create the key names and associate a value to each.

    value =...
    a[key]= value 
    k +=1

There are also some interesting data structures in the new 'collections' module that might be applicable:
