    elif ans=="3": 
        print("\n Goodbye") 
        ans = None
    else:

import re
def email():
    email = input("Enter Your email: ")
    match = re.search(r'[\w.-]+@[\w.-]+.\w+', email)

    if match:
        print ("Valid email, Your are now logged in :D "), match.group()
        print("""

    anykey=input("Enter anything to return to the menu")
    menu()
import random
def spam():
 random.randrange(1,1000)
print("This is how much spam you have!")

menu()

您可以将控制权交还给任何调用inbox()或sent()的函数。使用return语句而不是在上述2个函数中调用menu()。像这样：

def inbox():
    print("You have no mail, come back later.")
    anykey=input("Enter anything to return to the menu")
    return

def sent():
    print(" You have sent 1 piece of mail to m.mazi@gmail.com ")
    anykey=input("Enter anything to return to the menu")
    return
