Question

有人可以让我知道为什么会有SyntaxError吗？我使用macOS Mojave，并安装了IDLE版本3.7.1。

if name == 'Alice':
    print('Hi, Alice.')

    elif age < 12:
        print('You are not Alice, kiddo.')

        elif age > 2000:
            print('Unlike you, Alice is not undead, immortal vampire.')

            elif age > 100:
            print('You are not Alice, grannie.')

Answer 1

缩进是错误的：

name = input('whats your name? ')
age = int(input('whats your age? '))
if name == 'Alice':
    print('Hi, Alice.')
elif age < 12:
    print('You are not Alice, kiddo.')
elif age > 2000:
    print('Unlike you, Alice is not undead, immortal vampire.')
elif age > 100:
    print('You are not Alice, grannie.')

Answer 2

'elif'应该与'if'具有相同的缩进量

删除精灵之前的空白

if test expression:
    Body of if
elif test expression:
    Body of elif
else:
    Body of else

elif语句SyntaxError：语法无效
