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_...
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...

While you can use the extend() method to add a list to another list, concatenation only requires the use of one symbol: the plus sign (+). Lists are not the only object which can be concatenated. Any iterable object, such as a dictionary or a tuple, can be concatenated. Two objects...
Can you use Negtive index number in Python? Answer is YES!. Mostly case where you can use this is when you have to print last Index of string but you don't know the length of string. Example= "print last index of this string" --> you don't know the length then how print last[...
