在我的头顶，这里是第一部分：

展开 | 选择 | Wrap | 行号

谢谢，这是有道理的我无法找到一个示例显示使用枚举来对列表中的行进行编号，这确实有帮助。行打印的确切内容"％d：％s"％（i，word）是什么意思？

这称为字符串格式化。在引号内，％具有特殊含义。 此处是文档。

基本上，它表示打印一个（d）ecimal后跟一个''：''后跟一个（s）tring，其中十进制在i中，字符串在word中（实际上是（i，word） ）元组）。

I am new to programming and am trying to teach myself python. I have two questions how do you use a for loop to print out the lines from a list with the line numbers then the word and then I also was wondering what the tag was to print out the three longest, shortest, and middle length words along with their actual lengths

Off the top of my head, here''s the first part:

Expand|Select|Wrap|Line Numbers

Thanks, that makes sense I couldn''t find an example showing to use enumerate to number the lines of the list anywhere, this really helped. What exactly does the line print "%d: %s"%(i, word) mean?

That''s called "string formatting". Inside quotes the % has special meaning. Here is the documentation.

Basically, it says print a (d)ecimal followed by a '': '' followed by a (s)tring, where the decimal is in i and the string is in word (actually the (i, word) tuple).
