Python：期望缩进块 [英] Python: Expected an indented block

问题描述

我认为所有内容都在这里缩进，但我在 else：语句中得到 IndentationError：预期缩进块。我在这里犯了一个明显的错误吗？

I thought everything was properly indented here but I am getting an IndentationError: expected an indented block at the else: statement. Am I making an obvious mistake here?

def anti_vowel(text):
    new_string = ""
    vowels = "aeiou"
    for letter in text:
       for vowel in vowels:
           if (lower(letter) == vowel):
               #do nothing
           else:
               #append letter to the new string
               new_string += letter
    return new_string

推荐答案

不执行任何操作转换为使用传递关键字来填充其他空块（这是不允许的）。有关详细信息，请参阅官方文档。

Do nothing translates to using the pass keyword to fill an otherwise empty block (which is not allowed). See the official documentation for more information.

def anti_vowel(text):
    new_string = ""
    vowels = "aeiou"
    for letter in text:
       for vowel in vowels:
           if (lower(letter) == vowel):
               #do nothing
               pass
           else:
               #append letter to the new string
               new_string += letter
    return new_string
