Question

我很难过。我仔细查看了我的代码，但却无法找出为什么我的代码有了无效的语法。任何帮助将不胜感激！感谢。

def nameReverse():

    name = str(input("Enter your full name: "))
    testName = name.split()

    if len(testName)>1:

    firstName=testName[0]
    lastName=testName[1]
    print (lastName,firstName)

def main():
    nameReverse()

main()

Answer 1

如果是python 2.x，你应该使用

name = str(raw_input("Enter your full name: "))

完整代码：

def nameReverse():

    name = str(raw_input("Enter your full name: "))
    testName = name.split()

    if len(testName)>1:

        firstName=testName[0]
        lastName=testName[1]
        print (lastName,firstName)

def main():
    nameReverse()

main()

Answer 2

我得到的唯一错误是缩进错误。这是python，所以缩进很关键。您的if语句缩进不正确。这是你想要的：

def nameReverse():
    name = str(input("Enter your full name: "))
    testName = name.split()

    if len(testName)>1:
        firstName=testName[0]
        lastName=testName[1]
        print (lastName,firstName)

def main():
    nameReverse()

main()
