Python搜索列表中存在多个值

def has_multiple_values(lst, target):
    count = 0
    for item in lst:
        if item == target:
            count += 1
    return count > 1

# 示例用法
my_list = [1, 2, 3, 2, 4, 5]
target_value = 2
result = has_multiple_values(my_list, target_value)
print(result)  # 输出 True

def has_multiple_values(lst, target):
    return lst.count(target) > 1

# 示例用法
my_list = [1, 2, 3, 2, 4, 5]
target_value = 2
result = has_multiple_values(my_list, target_value)
print(result)  # 输出 True
