Python安装 (图文超级详细)

一、Python安装

1. 下载 Python

访问 Python 官网
https://www.python.org/
选择Downloads下拉框点击Windows选项卡；
根据自己电脑的配置选择合适的版本下载，本文选择Python 3.12.8 在Windows x64环境下安装 x64 Installer
下载完后，单击右上角.exe文件

2. 安装 Python

（1） 运行安装程序：

双击下载的 .exe 安装文件，开始安装过程。- 在安装过程中，可以选择默认安装路径，也可以自定义安装路径，我这里改成了自己设置的路径（D:\Python）。
2）完成安装：- 安装完成后，点击“关闭”关闭安装程序。

3. 验证安装

（1）打开命令提示符：

按 Win + R 打开运行对话框，输入 cmd 并按回车，打开 命令提示符。
（2）检查 Python是否安装成功：在命令行中输入以下命令，确认安装成功：
python
如果安装成功，你将看到类 似于以下输出：
Python 3.12.8 (tags/v3.12.8:2dc476b, Dec  3 2024, 19:30:04) [MSCv.1942 64 bit (AMD64)] on win32Type "help", "copyright", "credits" or "license" for more information.
