檢查列表是否包含類型？

Question

什麼是我可以檢查列表中某種類型存在的最快方法？

我希望我能做到以下幾點：

class Generic(object) 
    ... def ... 
class SubclassOne(Generic) 
    ... def ... 
class SubclassOne(Generic) 
    ... def ... 

thing_one = SubclassOne() 
thing_two = SubclassTwo() 
list_of_stuff = [thing_one, thing_two] 

if list_of_stuff.__contains__(SubclassOne): 
    print "Yippie!" 

編輯：想留蟒蛇2.7世界中。但3.0解決方案將可以！

Answer 1

if any(isinstance(x, SubclassOne) for x in list_of_stuff):

Answer 2

您可以使用any和isinstance。

if any(isinstance(item, SubClassOne) for item in list_of_stuff): 
    print "Yippie!"
