.sort is an in-place function, and it doesn't return anything. What you want to do instead is just call .sort on the array without reassigning the variable, or use sorted which returns the sorted array:

def sort_players_based_on_experience(self) :
    self.__players_list.sort(key=lambda x: x.get_experience())
    return self.__players_list

or

def sort_players_based_on_experience(self) :
    self.__players_list = sorted(self.__players_list, key=lambda x: x.get_experience())
    return self.__players_list
