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...

Can these two Python functions: defnegativeList(a):return[-eforeina]defnegativeTuple(a):returntuple(-eforeina) be replaced by an equvalent single generic functionnegative(a)? 解决方案 You can determine the type at run time defnegative(a):returntype(a)(-eforeina)...
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。
Similarly, The type and default value of the second to fifth parameter are string:"mnist"; float:0.01; bool:True; tuple:(1,2); list:[1,0.5,'test', "TEST"]. The seventh parameter is a nested dictionary of type dict, which also contains 7 parameters, with the same type and default ...
