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 解析看不懂?免费查看同类题视频解析查看解答 特别推荐 热点考点 2022年高考真题试卷汇总 2022年高中期中试卷汇总 ...
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...
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_...

Bug report Bug description: The enumerate object (and also the itertools.pairwise since #118219) re-uses tuples when possible. It does this by checking the reference count to be 1: // from enum_next in enumobject.c if (Py_REFCNT(result) ...
Hints: In case of input data being supplied to the question, it should be assumed to be a console input. We use itemgetter to enable multiple sort keys. Solutions: from operator import itemgetter, attrgetter l = [] while True: s = input() if not s: break l.append(tuple(s.split(",...
因此，当尝试将字符串与元组连接时，即logging.info("Database Error: " + e.args)，它会崩溃：
