inspect 模組

昨天在infoq上看到豆瓣架構師演講有提到這個模組 今天找來文檔看看

Doc：這樣寫到

The inspect module provides several useful functions to help get information about live objects such as modules, classes, methods, functions, tracebacks, frame objects, and code objects.

這個模組是針對模組，類，方法，功能等對象提供些有用的方法。例如可以協助我們檢查類的內容，檢查方法的代碼，提取和格式化方法的參數等。

 

#coding:utf8 import inspectimport os class Test(object):    """Test Class """    def test(self):        self.fuc = lambda x:x class Testone(Test):    pass #檢查類型，模組，類，方法，產生器，代碼等都可以print inspect.ismodule(os) print inspect.isclass(Test) print inspect.getdoc(Test)print inspect.getsourcefile(Test) #檔案路徑print inspect.getsourcelines(Test) #代碼塊，每行一個元素，組成數組print inspect.getsource(Test) #代碼塊 帶縮排#列印全域變數中的模組對象myglobals = {}myglobals.update(globals())modules = [value           for key, value in myglobals.items()           if inspect.ismodule(value)]print modules  #查看類的可調用方法for name, value in inspect.getmembers(Test, callable):    print "    Callable:", namefor name, value in inspect.getmembers(Test(), callable):    print "   Instance Callable:", namedef hello():    print inspect.stack()[0][3]    print inspect.stack()hello()具體項目中的用法還不瞭解。
