最后,如果新的旋转位置超出了最后一个字母(alphabet[-1])的位置,那么就需要旋转回到字母表的开头。为此,您需要从旋转后的位置(rotated_pos - len(alphabet))减去字母表的长度,然后使用chr()将字母返回到新的位置。 用rotate_chr()作为你的变换函数,你可以用map()用凯撒密码算法加密任何文本。下面是一个使用 st...

Now, map() returns a map object, which is an iterator that yields items on demand. That’s why you need to call list() to create the desired list object.For another example, say you need to convert all the items in a list from a string to an integer number. To do that, you ...
