一、序章

1、Python的后台是PyPI。
2、PyPI是一个拥有成千上万第三方模块的地方。

二、环境搭建

1、Python官网地址

https://www.python.org，在download中下载对应系统最新版本即可。

2、安装安装包

勾选“Add Python 3.10 to PATH”，然后点击“Install Now”，默认安装就可以了。

3、使用IDLE编译器进行学习

1）IDLE全称是Integrated Development and Learning Environment，即Python的综合开发环境和学习环境。
2）IDLE有两个模式，交互模式和编辑器模式。
3）IDLE打开路径：菜单—>Python 3.10—>IDLE

4）默认打开的是IDLE的交互模式，即你给它一个指令，它立刻给你一个反馈。
5）练习输入第一行代码

>>>print("Hello World!")
Hello World!

6）Python还可以进行计算

>>>1+1
2

4、《Python之禅》-Python的设计哲学

>>>import this
The Zen of Python, by Tim PetersBeautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!
