在不使用全局变量的情况下执行python列表操作

def list_operation(my_list):
    # 对列表进行操作
    my_list.append(1)
    my_list.remove(2)
    return my_list

# 调用函数进行列表操作
my_list = [2, 3, 4]
result = list_operation(my_list)
print(result)

my_list = [2, 3, 4]
new_list = [x for x in my_list if x != 2]
print(new_list)

class ListOperation:
    def __init__(self, my_list):
        self.my_list = my_list

    def remove_element(self, element):
        self.my_list.remove(element)

    def append_element(self, element):
        self.my_list.append(element)

# 创建对象并进行列表操作
my_list = [2, 3, 4]
list_operation = ListOperation(my_list)
list_operation.remove_element(2)
list_operation.append_element(1)
print(my_list)
