有没有办法重新定义 python 中的内置 class ？

Question

Is there a way that you can redefine built-in classes in python (eg int). When I just do class int then the type is __main__.int not int , is there any way to define it without the __main__ ?

Answer 1

i don't think thats possible without editing python source written in c but you can inherit from the built in classes like int then add your methods like:

class MyList(list):
    def sumOfAll(self):
        return sum(self)
myList = MyList([1,2,3])
print(myList.sumOfAll())

Output: 6
