如何在Python中打开和编辑现有文件? [英] How to open and edit an existing file in Python?

问题描述

我一直在研究各种不同的程序来练习我的Python，其中最著名的是我自己选择的冒险游戏，到目前为止，它已有1000多行.最近，我一直在尝试从Python内部编辑文件，但似乎无法弄清楚.例如，如果我像这样将变量设置为用户输入: input1 = raw_input("What is your favorite food?")然后，假设我要将此文本保存到已经存在的.txt文件中，例如food.txt.我该怎么办?

I've been working for a while now on a variety of different programs to practice my Python, the most notable being my choose-your-own-adventure game, which is well over 1000 lines so far. More recently, I have been trying to edit files from within Python, and I can't seem to figure it out. For instance, if I set a variable to a user input like so: input1 = raw_input("What is your favorite food?") Then, let's say I want to save this text to a .txt file that already exists, like food.txt. How would I do that?
