python新功能.我需要帮助分配数值的电子邮件列表

Question

我目前正在接受我的第一个python类，我需要帮助分配数字到电子邮件时，它被添加到我的电子邮件列表。这样，当有人想从列表中删除电子邮件时，他们可以看到该电子邮件分配给了什么号码，只需输入号码即可。我将提供我的代码，以及最终产品应该是什么样子的视频。

注:我不知道所有的专业术语，所以我希望你们能理解。谢谢!

menu = 0
list = []
while menu < 4:
print(" 1 to add an emailn 2 to remove an emailn 3 to print listn 4 to EXIT menu")
print("")
menu = int(input("Enter: "))
print("")
if menu == 1:
enter_email = input("What is the email: ")
list.insert(1, enter_email)
print("")
print("The email:", enter_email, "was successfully added to the list")
print("")
elif menu == 2:
remove_email = input("What email would you like to remove: ")
if remove_email in list:
list.remove(remove_email)
print("")
print("The email, ", remove_email, ", was removed from the list")
print("")
else:
print("")
print("That email does not exist")
print("")
elif menu == 3:
email_list = ', '.join(str(item) for item in list)
print("")
print(email_list)
print("")
elif menu == 4:
print("Exited successfully, have a nice day")

没有尝试过很多，不知道从哪里开始。

Salvatore!不错的代码，我想你已经很接近解决方案了。在Python中，有一个名为enumerate的内置函数，它自动分配一个数字以在列表中拥有一个计数器。

在你的代码中，我会添加这样的东西:

*注意，当变量menu = 3时，我只是更改了代码

menu = 0
list = []
while menu < 4:
print(" 1 to add an emailn 2 to remove an emailn 3 to print listn 4 to EXIT menu")
print("")
menu = int(input("Enter: "))
print("")
if menu == 1:
enter_email = input("What is the email: ")
list.insert(1, enter_email)
print("")
print("The email:", enter_email, "was successfully added to the list")
print("")
elif menu == 2:
remove_email = input("What email would you like to remove: ")
if remove_email in list:
list.remove(remove_email)
print("")
print("The email, ", remove_email, ", was removed from the list")
print("")
else:
print("")
print("That email does not exist")
print("")
elif menu == 3:
for counter, value in enumerate(list):
print(counter, value)
print("")
elif menu == 4:
print("Exited successfully, have a nice day")

希望能帮到你!!
