1) If you're just trying to create temporary files, you would be much better 
   off using the tempfile module. It's more secure and saves you the hassle 
   of doing it yourself: http://docs.python.org/lib/module-tempfile.html 

2) Since all you're doing is adding a bunch of numeric values to each other
   to build the string, why wouldn't you just create a random number between
   0 -> 99999 and use that?

3) If you really, really, really still want to do this, the best way I can 
   think of would be to use the string format operator: 

import random
def random_name():
    a = random.randint(0,9)
    b = random.randint(0,9)
    c = random.randint(0,9)
    d = random.randint(0,9)
    e = random.randint(0,9)
    random_name = '%s%s%s%s%stemp.txt' % (a,b,c,d,e)
    return random_name

OR, using suggestion 2 above:

import random
def random_name():
    num = random.randint(0,99999)
    random_name = '%stemp.txt' % (num)
    return random_name
