Python:如何根据布尔变量反转列表成员关系检查？

def check_membership(item, lst, invert=False):
    return item in lst if not invert else item not in lst

# 示例使用
my_list = [1, 2, 3, 4, 5]
item_to_check = 3

# 正常检查
print(check_membership(item_to_check, my_list))  # 输出: True

# 反转检查
print(check_membership(item_to_check, my_list, invert=True))  # 输出: False

def check_membership(item, lst, invert=False):
    return (item in lst) != invert

# 示例使用
my_list = [1, 2, 3, 4, 5]
item_to_check = 3

# 正常检查
print(check_membership(item_to_check, my_list))  # 输出: True

# 反转检查
print(check_membership(item_to_check, my_list, invert=True))  # 输出: False
