python - PyCharm 中的注释和嵌套代码折叠

Question

为什么 PyCharm 将嵌套代码块末尾的换行符折叠到前一个 block 中？

示例(尝试折叠第一个“if” block ):

def print_me(a):

# newline comment
    if a == 'me':
        dummy_padding = ''
        if not dummy_padding:
            favorite_place = 'zoo'
            print(a)
        else:
            pass

# invisible newline comment
    elif a == 'you':
        dummy_padding = ''
        pass

# visible newline comment
    elif a == 'us':
        dummy_padding = ''
        if not dummy_padding:
            favorite_place = 'movies'
            print(favorite_place)

    # visible indented comment
    elif a == 'them':
        dummy_padding = ''
        pass

    return a

Python 中是否有规范规定函数内的注释应始终缩进？如果没有，是否有某种方法可以调整 PyCharm 中的设置，以便在折叠嵌套代码时不会消失换行符注释？

PEP8指出

Block comments generally apply to some (or all) code that follows them, and are indented to the same level as that code.

所以我认为您的以下评论没有缩进导致了这种行为。

如果您将“#invisible newline comment”缩进到与后面的 elif 相同的级别，您将看到 PyCharm 不再将其折叠到上面的 block 中。

# newline comment
    if a == 'me':
        dummy_padding = ''
        if not dummy_padding:
            favorite_place = 'zoo'
            print(a)
        else:
            pass

    # invisible newline comment  -- now not folded
    elif a == 'you':
