所以我没有收到任何错误，但它没有正确运行。用# **突出显示的代码位是错误的地方。因此，当我运行它时，无论是否放入.com或.co.uk或.org.uk，它总是会打印出我的代码无效。程序无法正常工作

import time 
#Imports the time library. 
#3 
#Email validator 
#Make a program to check whether an email address is valid or not. 
#You could make sure that there are no spaces, that there is an @ symbol and a dot somewhere after it. Also check that the end parts of the address are not blank. 
#Extensions: 
#1. When an email address is found to be invalid, tell the user exactly what they did wrong with their email address rather than just saying it is invalid 
#2. Allow the user to choose to give a text file with a list of email addresses and have it process them all automatically. 
print("Only .com or .co.uk or .org.uk are accepted.") 
def ev(): 
    #starts the definition and defines the command. 
    time.sleep(1) 
    #1 second wait 
    email = input("Email: ") 
    dot = "." 
    at = "@" 
    space = " " 
    com = ".com" 
    couk = ".co.uk" 
    org = ".org.uk" 
    if at not in email: 
     print("Invalid. There is no @ in your email.") 
     #Says email is invalid as there is no @ 
     ev() 
    elif dot not in email: 
     print("Invalid. There is no .(dot) in your email.") 
     #Says email is invalid as there is no . 
     ev() 
     #Loops to asking for the email again 
    elif space in email: 
     print("Invalid. There shouldn't be any spaces in your email.") 
     #Says email is invalid as there is a space 
     ev() 
     #Loops to asking for the email again 
    elif com not in email or couk not in email or org not in email: # ** 
     print("This email is not valid. Only .com or .co.uk or .org.uk are accepted.")** 
     ev() 
     #Loops to asking for the email again 
    else: 
     print("Valid!") 
ev() 
#Ends the definition so it starts automatically.

回答：

你需要and，而不是or：

试试这个：

elif com not in email and couk not in email and org not in email: 
    print("This email is not valid. Only .com or .co.uk or .org.uk are accepted.")** 
    ev() 
    #Loops to asking for the email again
