在Python中,can only concatenate tuple (not "int") to tuple这个错误提示通常出现在尝试将整数(int)与元组(tuple)进行不适当的连接操作时。以下是对这个问题的详细解答: 解释Python中的元组(tuple)和整数(int)数据类型: 元组(tuple):元组是Python中的一种不可变的数据结构,用于存储一系列的元素。
TypeError: can only concatenate tuple (not"int") to tuple Python 中不允许将整数连接到元组,这就是发生 TypeError 的原因。 要修复TypeError: can only concatenate tuple (not "int") to tuple,我们可以使用元组而不是整数,因为我们可以连接两个元组,但不能连接具有任何其他数据类型的元组。 代码示例: nums_...
In Python tuples are an important data structure that allows you to group many values together. But some beginners may find it confusing to use tuples inside functions. This article will explain what tuples are and how to use them properly in functions. We will also discuss some real-world...

不是很明白你的意思(向量乘积?) 但这个错误的意思是:tuple类型(元组)不支持这种乘法操作 你的n1和n2都是tuple类型,这样做乘法是会出错的 你可以 n1 * num , num 为int类型 即 乘法操作满足, type * int,有一个乘数需得是int 分析总结。 想写一求向量乘积来判断是否平行的代码求问该怎么改反馈...
