2、创建 Flask 应用 在Python 文件中,首先需要导入 Flask 模块,然后创建一个 Flask 应用对象。 示例代码如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 from flaskimportFlask app=Flask(__name__) 这个代码会创建一个名为 app 的 Flask 应用对象。 3、编写路由 在Flask 应用中,路由用于指定请求的...
事实上,你几乎从来不希望你的程序从第一行代码开始,简单地执行每一行,一直到最后。流程控制语句可以决定在什么条件下执行哪些Python指令。 这些流程控制语句直接对应于流程图中的符号,所以我将提供本章中讨论的代码的流程图版本。图 2-1 显示了下雨时该做什么的流程图。沿着箭头所指的路线从头到尾走。 图2-1:告诉...
第1 章:交互式 Shell解释了如何使用 Python 的交互式 Shell 逐行实验代码。 第2 章:编写程序介绍了如何在 Python 的文件编辑器中编写完整的程序。 在第3 章:猜数字中,您将编写本书中的第一个游戏,猜数字游戏,要求玩家猜一个秘密数字,然后提供关于猜测是否太高或太低的提示。 在第4 章:讲笑话程序中,您将...

Creating them can be a challenge, taking as much time, if not more, than writing the actual game code. Rather than create your own assets, you can download free or low-cost assets to use in your game. Many artists and designers provide sprites, backgrounds, fonts, sounds, and other ...

Pythonis a very popular general-purpose interpreted, interactive, object-oriented, and high-level programming language. Python is dynamically-typed and garbage-collected programming language. It was created by Guido van Rossum during 1985- 1990. Like Perl, Python source code is also available under ...

Python is a powerful, object-based, high-level programming language with dynamic typing and binding. Due to its flexibility and power, developers often employ certain rules, or Python design patterns. What makes them so important and what do does this mean for the average Python developer?
