为何你发的求助帖都是收费贴？
别人回答问题还要给你付鱼币？
别人解决你的问题你也不采纳。 hrpzcf 发表于 2021-7-1 16:50

给你们
{:10_312:}其实print中不用加\n的，默认print中就是\n换行，直接print()就行 另外就是按照前一个的写法，是在每次第二层循环中打印一次，而后面一个写法是在第二次循环结束后打印一次，结果肯定不一样 首先要分清楚两层for循环都是干嘛的
内层循环单次打印一个乘法语句
外层循环单次打印一行乘法语句
所以print('\n')放到内层循环内，就是每打印一句换行依次（即第一种情况）
放到内层循环外，外层循环内，就是对应打印完一行再换行（合理情况） 取决于在的层数 那肯定不一样啊
