python中每一個(gè)對(duì)象或者對(duì)象的方法都有可以使用三種方式查看相關(guān)的使用方法和幫助文檔。

class SampleClass(object):
    """Summary of class here.

    Longer class information....
    Longer class information....

    Attributes:
        likes_spam: A boolean indicating if we like SPAM or not.
        eggs: An integer count of the eggs we have laid.
    """

    def __init__(self, likes_spam=False):
        """Inits SampleClass with blah."""
        self.likes_spam = likes_spam
        self.eggs = 0

    def public_method(self):
        """Performs operation blah."""


if __name__ == '__main__':
    
    # a = '5'  # xxxxx
    print(SampleClass.__doc__)
    print(dir(SampleClass))

    print(help(SampleClass))

    print(dir(SampleClass.public_method))
    print(help(SampleClass.public_method))

直接調(diào)用對(duì)象或者方法的doc屬性，或者使用dir()或者使用help()來(lái)查看就可以了。
