python - PEP8 E112 不应该出现缩进错误？

Question

我已经阅读了有关该错误的大部分内容，但我看不出它与我正在编写的这个类有何关系。

class Mr:
    def __init__(self, directory=False, config=False, trust_all=False):
        self.directory = directory or os.getcwd()
        self.control_dir = os.path.join(self.directory, '.bzr')

    def update(self):
        #print 'Not today'

    def add(self, name=False, repository='lp:charms'):
        if not name:
            raise Exception('No name provided')

    def checkout(self):
        #t

    def remove(self, name=False):

            raise Exception('No name provided')

    def _write_cfg(self):
        #t

    def _read_cfg(self):
        #t

    def _check_repository_exists(self):
        # Eventually do more checks to make sure it is a shared repository
        # and not a branch, etc.
        return os.path.exists(self.control_dir)

它提示这些行:

def add(self, name=False, repository='lp:charms'):
def remove(self, name=False):
def _read_cfg(self):
def _check_repository_exists(self):

Answer 1

在这 4 个函数之前都有“空”函数。向这些函数添加 pass 语句:

def update(self):
    #print 'Not today'
    pass

def checkout(self):
    #t
    pass

def _write_cfg(self):
    #t
    pass

def _read_cfg(self):
    #t
    pass
