Easy password generator in Python with iteration next/yield

pass_gen.py

from string import ascii_lowercase, ascii_uppercase
import random

chars = ascii_lowercase + ascii_uppercase + "0123456789!?@#$*"
n = int(input("Enter password length: "))
m = int(input("Enter how many passwords to generate: "))


def gen_char_password(n):
    for i in range(n * m):
        index = random.randint(0, len(chars) - 1)
        yield chars[index]


gen = gen_char_password(n)
for i in range(m):
    for i in range(n):
        print(next(gen), end='')
    print('')
