Question

我想使用变量'classname'从列表中删除对象

list = [A, A, B]                    #objects inside a list  
classname = input() .               #x = A
list.remove(classname)              #the problem is that classname is a string
                                    #and the list has no strings

Answer 1

某些对象知道其名称。如果A和B是类，函数，方法，描述符或生成器实例，则可以使用definition.__name__确定其名称。

class A:
    pass

class B:
    pass

l = [A, B, A, B]
remove = "A"
print([x for x in l if x.__name__ != remove])
# [<class '__main__.B'>, <class '__main__.B'>]

输入一个类名，然后从列表中删除该类的对象
