python 获取类方法

As a newbie to the excellent world of Python development, I'm not always familiar with the methods provided by imported classes.  Oftentimes these classes are well-documented but in the case that methods aren't documented, I found the dir function useful for getting a list of methods:

作为Python开发卓越世界的新手，我并不总是熟悉导入类提供的方法。 通常，这些类的文档有据可查，但是在没有文档记录方法的情况下，我发现dir函数对于获取方法列表很有用：

# dir({object})dir(difflib)"""Returns:['Differ', 'HtmlDiff', 'IS_CHARACTER_JUNK', 'IS_LINE_JUNK', 'Match', 'SequenceMatcher', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '_calculate_ratio', '_count_leading', '_file_template', '_legend', '_mdiff', '_namedtuple', '_styles', '_table_template', '_test', 'context_diff', 'get_close_matches', 'heapq', 'ndiff', 'reduce', 'restore', 'unified_diff']"""

The snippet above does exactly what you would expect -- provides a list of method names for the viewing!

上面的代码片段完全符合您的期望-提供用于查看的方法名称列表！
