safe enough 8-character short unique random string

Question

I am trying to compute 8-character short unique random filenames for, let\'s say, thousands of files without probable name collision. Is this method safe enough?

Answer 1

You can try this

import random
uid_chars = ('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u',
             'v', 'w', 'x', 'y', 'z','1','2','3','4','5','6','7','8','9','0')
uid_length=8
def short_uid():
    count=len(uid_chars)-1
    c=''
    for i in range(0,uid_length):
        c+=uid_chars[random.randint(0,count)]
    return c

eg:

print short_uid()
