Python Variable variable for directories in a folder

The title may sound confusing so here is what I want...

I have the following code:

import os
dir_list = os.walk('aFolder').next()[1]     #aFolder is the directory location

SizeOfList =  len(dir_list)
NumbOfList = 0

while (NumbOfList < SizeOfList):
    print dir_list [NumbOfList]
    NumbOfList = NumbOfList + 1

This code gets all the folders (not including subfolders) in the folder called 'aFolder' and shows them to the user. However, I want to store these folder names as different variables. The problem I have here is, I don't know the number of folders in this directory so I can't set 1 variable to dir_list [0] and another to dir_list [1] etcetera.

I need this because I want to select and choose certain folders with an if statement. If you have an alternative to doing this than mine, I will happily accept it.

My solution to this was using a while loop. However, I can't figure out how to change the variable name each time the while loop repeats. I have tried this, this and this. The third link was the closest, but I still can't figure out how to implement it.

Thank you in advance to anyone who helps.

If you want to see if a string is a substring of a folder in your list:

for directory in dir_list:
     #Do stuff for everyone
     if "mysubstring" in directory:
         dospecialstuff()

You asked me to expand my comment. Here it is:

import os

d=dict()
dir_list = os.walk('/tmp').next()[1]

for idx in range(len(dir_list)):
  d.update({dir_list[idx]: idx})

for k, v in d.items():
  print "k=", k, "v=", v
  d.update({k: v+1})  # to update the variable
  print "new value of <%s>"%(k), d[k]
  print
