python的inspect模块

发现python有个好用的检查模块-inspect, 查看源文件发现它提供了不少好用的方法:
“”"
Here are some of the useful functions provided by this module:

ismodule(), isclass(), ismethod(), isfunction(), isgeneratorfunction(),
isgenerator(), istraceback(), isframe(), iscode(), isbuiltin(),isroutine() – check object types

getmembers() – get members of an object that satisfy a given condition

getfile(), getsourcefile(), getsource() – find an object’s source code
getdoc(), getcomments() – get documentation on an object
getmodule() – determine the module that an object came from
getclasstree() – arrange classes so as to represent their hierarchy

getargspec(), getargvalues() – get info about function arguments
formatargspec(), formatargvalues() – format an argument spec
getouterframes(), getinnerframes() – get info about frames
currentframe() – get the current stack frame
stack(), trace() – get info about frames on the stack or in a traceback
“”"

举例:

import inspect
inspect.isbuiltin(abs)
True

import os
inspect.ismodule(os)
True

class C:pass
inspect.isclass(C)
True

class C(object):
    def foo(self):
        print 'here is foo'

    def bez(self):
        print 'here is bez'

inspect.getmembers(C, inspect.ismethod)
[('bez', "<"unbound method C.bez">"), ('foo', "<"unbound method C.foo">")]

上面要是不加inspect.ismethod的话,会将对象的所有默认属性都列出来

其他方法就一一列举
