問題描述

I'm sure this is covered in plenty of places, but I don't know the exact name of the action I'm trying to do so I can't really look it up. I've been reading an official Python book for 30 minutes trying to find out how to do this.
問題:我需要在一定長度的字段"中放入一個字符串.
Problem: I need to put a string in a certain length "field".
例如，如果姓名字段有 15 個字符長，而我的名字是 John，我會得到John"后跟 11 個空格來創建 15 個字符的字段.
For example, if the name field was 15 characters long, and my name was John, I would get "John" followed by 11 spaces to create the 15 character field.
我需要它適用于為變量name"輸入的任何字符串.
I need this to work for any string put in for the variable "name".
我知道這可能是某種形式的格式，但我找不到執行此操作的確切方法.幫助將不勝感激.
I know it will likely be some form of formatting, but I can't find the exact way to do this. Help would be appreciated.
