python的inspect模組

發現python有個好用的檢查模組-inspect, 查看源檔案發現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
“”"

舉例:

import inspectinspect.isbuiltin(abs)Trueimport osinspect.ismodule(os)Trueclass C:passinspect.isclass(C)Trueclass 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的話，會將對象的所有預設屬性都列出來

其他方法就一一列舉
