How can I begin a string with a number in a python program?

February 16, 2022

I have written the following python project which provides a random output of 20 strings and I have set the limit of it to be less than 1,00,000 during each run and every string shall be unique.

Now I want to add a line of code that helps me start each output with a number

To make it more simple here is an example:

Output right now: AtcaF268d1whnkwiwuniw

Output I need: 7atcaF268d1whnkwiwuni

So each output is a random number.

Here is the code to edit

import random

results = []
while len(results) < 100000:
    result_str = ''.join((random.choice('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') for i in range(20)))
    if result_str not in results:
        results.append(result_str)

with open('string_test.txt','a') as out:
    out.write( '\n'.join(results) )

>Solution :

just gernerate it seperatly i guess?

import random

results = []
while len(results) < 100000:
    result_str = random.choice('0123456789') + ''.join((random.choice('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789') for i in range(19)))
    if result_str not in results:
        results.append(result_str)

with open('string_test.txt','a') as out:
    out.write( '\n'.join(results) )
