What's the best way to generate random strings of a specific length in Python?

Question

For a project, I need a method of creating thousands of random strings while keeping collisions low. I\'m looking for them to be only 12 characters long and uppercase only.

Answer 1

This function generates random string of UPPERCASE letters with the specified length,

eg: length = 6, will generate the following random sequence pattern

    import random as r

    def generate_random_string(length):
        random_string = ''
        random_str_seq = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
        for i in range(0,length):
            if i % length == 0 and i != 0:
                random_string += '-'
            random_string += str(random_str_seq[r.randint(0, len(random_str_seq) - 1)])
        return random_string
