Here’s a sample python script of generating random string. (generate_random_string.py)

#!/bin/env python

import random,string,sys

char_set = string.ascii_lowercase + string.ascii_uppercase + string.digits

s = ''.join(random.choice(char_set) for x in range (int(sys.argv[1])))

print s

generate 40 random characters.

# ./generate_random_string.py 40
