Import functions in randomized order in Python

I've already created modules containing functions that drill different mental math techniques by randomly generating certain kinds of problems. What I want to do is make a review program that imports 5 problems from each module, but in a random order.

Here's an example of one of the modules:

import random

class font:
    underline = '\033[4m'
    end = '\033[0m'

def eleven(problems):

    for i in range(problems):
    num1 = random.randint(10,99)
    answer = num1 * 11

    print "\n    %d" % num1
    print "  " + font.underline + "x 11" + font.end

    raw_input()

    if answer >= 1000:
        pad = " " 
    else:
        pad = "  "

    print pad, answer

I've run several searches both on Google and on this site, but I couldn't find anything directly relevant. Part of the problem is I might not recognize a solution if it was staring me in the face, knowing as little as I do about Python. Ideally I would wade through the documentation and find my own answer, but I was hoping someone could at least point me in the right direction.

Thanks.
