        if chars == 50:
            add_num = False
            searching()

    while chars == False:
        chars -= 1
        if chars == 12:
            add_num = True
            searching()
        print(chars)
    if found == True:
        stats()

    #start
    res = ''.join(random.choices(string.ascii_lowercase + string.ascii_uppercase + string.digits, k = chars))
    res += ".onion"
    ######
    searching()

print("Press enter to find random dark-net website")
usr_input = input("> ")
print("Searching for website...")
time.sleep(10)
searching()

My code suppose to find random dark-net websites by generating random strings with numbers and letters.

I know what this error means but I don't know how to fix it.

Thanks in advance!
