tuple1 = ("str",1,["a","b","c"],4) tuple2 = ("hello",) print(tuple1[0]) print (tuple1[1:3]) print (tuple1[1:]) print (tuple2 * 2) print (tuple1+tuple2) 注意事项,tuple2 的后面有一个逗号 执行结果如下 str (1, ['a', 'b', 'c']) (1, ['a', 'b', 'c'...

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...
