前言
1、对于一些场景中系统自带的python3.7.5版本无法满足使用需求，需要在环境中安装，编译指定版本的python3，以下详细列出了python3源码编译，安装，以及环境变量配置和使用步骤。
2、以下使用V10 SP3 x86架构操作系统做演示，对于不同架构，不同版本的系统，安装步骤同理！

一 系统环境

[root@localhost ~]# nkvers
############## Kylin Linux Version #################
Release:
Kylin Linux Advanced Server release V10 (Lance)Kernel:
4.19.90-52.22.v2207.ky10.x86_64Build:
Kylin Linux Advanced Server
release V10 (SP3) /(Lance)-x86_64-Build23/20230324
#################################################

二 安装python3.12.4

2.1 安装编译需要的依赖包

如果网络可以正常连接互联网，直接执行，如果不能访问外网，需要将ISO镜像文件配置成本地yum源！！
[root@localhost ~]# yum install libffi-devel tcl-devel tk-devel perl-CPAN openssl-devel readline-devel sqlite-devel openssl -y

2.2 下载官网目前最新的python源码包

[root@localhost ~]# wget https://www.python.org/ftp/python/3.12.4/Python-3.12.4.tar.xz

2.3 解压Python-3.12.4.tar.xz
