Question

我之前问过这个问题，但没有回答（我的错，我没有提出问题）。我需要创建一个包含4个选项的菜单，但我不知道如何将user_input链接到实际的1,2,3,4程序。请帮帮....

Answer 1

您的代码似乎无法在任何地方提示输入。这是问题吗？

user_input = int( input("your prompt goes here") )
# PYTHON3

user_input = int( raw_input("your prompt goes here") )
# PYTHON2

顺便说一句：如果您不必将用户的输入用作数字（例如，您不需要对其进行任何数学运算），则不要将其转换为int并测试if user_input == "1"而不是if user_input == 1
