Python Help Needed!

I'm having trouble with the following Python script:

#!/usr/bin/python3

import random
import string

def generate_random_character(seed):
    """Generates a random alphanumeric character.
    """
    random.seed(seed, version=1) # Version parameter should be removed if using Python 2
    code = random.choice(string.ascii_uppercase + string.ascii_lowercase + string.digits)

    return code

def generate_random_codes(group_of_seeds):
    """Generates a number of random alphanumeric strings.
    """
    output = ""

    for i in range(len(group_of_seeds)):
        for seed in group_of_seeds[i]:
            output = generate_random_character(seed)

        output += "\n"

    return output

SEEDS_GROUP = ([113,205,84,36,30],
               [48,44,3,13,74],
               [88,17,60,29,47],
               [9,165,94,99,77],
               [58,113,78,248,128],
               [46,60,31,147,17]) 

print (generate_random_codes(SEEDS_GROUP))

I thought it would generate a number of random alphanumeric codes but the only output I get when I run it is a single character:

h

I already posted it on StackOverflow and a bundle of people kept saying it's a "one character fix", but that just seems to be repeating my problem!

Can anybody help? You should be able to execute it online here.

My guess would be that output is overwritten every time

And the one character fix would be to add a + in output +=generate_random....

Change

output = generate_random_character(seed)

to

output += generate_random_character(seed)

That should do the trick.

This. You need to add the the list, if you just use a = sign it'll overwrite the value each loop.

Don't know what you're trying to do exactly but using static seeds will always produce the same output. Computers are deterministic systems so the same starting conditions will always lead to the same results.
If that's not what you're trying to do, what you could do instead is generate a GUID then hash it and use it as a seed.

edit: ok guess you wanted fixed results

I find it puzzling when people try to make sense of computer nerds.

First thing to do when code doesn't work: set a break point and step through line by line.
