从元组列表中获取匹配值

def get_matching_tuples(tuple_list, condition):
    matching_tuples = []
    for tuple_item in tuple_list:
        if condition(tuple_item):
            matching_tuples.append(tuple_item)
    return matching_tuples

# 示例元组列表
tuple_list = [
    (1, 'apple'),
    (2, 'banana'),
    (3, 'orange'),
    (4, 'apple'),
    (5, 'grape')
]

# 示例条件函数，判断元组的第二个元素是否为'apple'
def condition(tuple_item):
    return tuple_item[1] == 'apple'

# 调用函数获取匹配的元组
matching_tuples = get_matching_tuples(tuple_list, condition)

# 打印匹配的元组
for tuple_item in matching_tuples:
    print(tuple_item)
