Pass generator 3.6 python blank screen -

when press f5(python idle) blank screen when follow press 1 go generator e.c.t

#all imports used     import random import time import re import sys import string  def menu():     print("welcome password generator , checker")     choice = int(input(""" 1) generate password 2) check password 3) quit """))      if choice == 1:         gp(10)     elif choice == 2:         cf()     elif choice == 3:         print("goodbye")         time.sleep(0.5)         print("come next time")         sys.exit()     else:         print("please select valid choice")  def cf():     print("welcome password checker")  #i think def underneath message maybe problem idk  def gp(num):      print("welcome password generator")     time.sleep(0.5)     print("this generator generates range of symbols,characters , numbers strongest , secure password")     password = " "      n in range(num):         x = random.randint(0,94)         password += string.printable[x]      return password     print (gp(12))  menu() 

short solution

if generating 12-character password string need, use string library , `random.choice:

import string import random  def gp(num)   return (''.join(random.choices(string.ascii_letters + string.digits, k=num)))  print (gp(12)) 

alternative solution without string package:

if don't want introduce dependency on string package, generate own valid characters string this:

def gp(num):    return (''.join(random.choices('abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz*&[](){}1234567890',k=num))
