Input a class name and remove an object of that class from a list

Question

I want to remove an object from a list using a the variable 'classname'

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

Some objects are aware of their names. If A and B are classes, functions, methods, descriptors, or generator instances, you can use definition.__name__ to determine their names.

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'>]
