How to allow a specific part of my program to write to a txt

Alright, So I've seen multiple ways to allow python programs to write to a specified txt, but none of the ones I've seen would be compatible with my program.

It's a number/password generator that can print anywhere from one line, to actual billions of lines of strings. But, the issue is that there is some dialog and options before it prints out the selected strings.

How do I make it so it only records and writes a certain part to a txt, Instead of the whole thing.

Here's a link to the github, And attached is the program. https://github.com/JasonDerulo1259/JasonsGenerator

Or alternatively, here is the raw code:

import time
import random
from random import randint
from random import choices
import sys
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","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","$","%","&","(",")","*",",","-",".","/",":",";","<","=",">","?","@","[","]","^","_","`","{","|","}","~","0","1","2","3","4","5","6","7","8","9"]
