import sys import time def chat():     print('hello there. name?')     name = sys.stdin.readline()     print('your name %s...interesting. name chat created have small planned out conversation when call me :)' % (name))     time.sleep(2)     print('how weather in town today?')     weather = sys.stdin.readline()     time.sleep(1.5)     print('your weather %s? weather in town quite sunny.' % (weather))     time.sleep(2)     print('this conversation can make @ moment. please patient while creator trys update me.')   def calculator():     print('how money have?')     money = int(sys.stdin.readline())     print('how paid?')     job = int(sys.stdin.readline())     print('how spend?')     spent = int(sys.stdin.readline())     week in range(0,30):             money = money + job - spent             print('week %s. money %s' % (week,money))    def jobber():     print('type talk short chat. type calc money calculator.')     choice = int(sys.stdin.readline())     if choice == 1:             chat()     if choice == 2:             calculator() 

use input() , convert lowercase

def jobber():      choice = input('type talk short chat. type calc money calculator.').lower()     if choice == "talk":             chat()     if choice == "calc":             calculator()
