Generate random string in Python

gistfile1.py

import string
import random

size = 2500 # or whatever lenght you want your random string to be
allowed = string.ascii_letters # add any other allowed characters here
randomstring = ''.join([allowed[random.randint(0, len(allowed) - 1)] for x in xrange(size)])

print randomstring

Thank you for this.

To help other coders, this is how you add character sets to the allowed variable:
allowed = string.ascii_letters + string.digits
