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

Your current method should be safe enough, but you could also take a look into the uuid module. e.g.

import uuid

print str(uuid.uuid4())[:8]

Output:
