下载Python的安装包非常简单#xff0c;只需要去官网就可以了#xff1a;https://www.python.org/downloads/windows/
但是有时候你可能需要环境测试#xff0c;需要安装很多版本的Python。
一个一个找倒是也可以#xff0c;但是我做了个自动筛选的脚本只需要去官网就可以了https://www.python.org/downloads/windows/
但是有时候你可能需要环境测试需要安装很多版本的Python。
一个一个找倒是也可以但是我做了个自动筛选的脚本直接汇总找出各子版本中的最高版本号的下载地址
import os
import re
from urllib.request import urlopen
from pprint import pprintimport packaging.version as pvdef version(url):ver re.search(python-(\d[\d\.abcr]\d), url, re.I).group(1)return pv.parse(ver)pattern ra href(https://www.python.org/[^]/python-[^]*?)
white [exe, msi]
black [embed, arm64, webinstall]url https://www.python.org/downloads/windows/
response urlopen(url)
text response.read().decode()M1 re.findall(pattern, text, re.I)
M2 sorted((version(url), url) for url in M1)
M3 [(ver, url) for ver, url in M2 if any(word in url for word in white) and not any(word in url for word in black)]keep {}
for ver, url in M3:ver2 ver.release[:2]if ver2 not in keep or ver keep[ver2]:keep[ver2] verM4 [(ver, url) for ver, url in M3 if ver in keep.values()]for ver, url in M4:# print(f{str(ver):12}: {url})print(url)其中需要安装一个版本号解析包使用以下命令安装 pip install packaging 二、程序步骤
简单介绍程序的执行步骤可以根据自己的需求进行修改
读取Python官网Windows安装包页面源代码。匹配出所有可访问的下载路径。用正则表达式取出程序文件名中的版本号其中Python的版本号存在2位和3位数字、和a/b/rc3中预发布版本。用packaging库解析版本号并根据版本号排序。按照黑名单black和白名单white模式筛选其中只保留 exe 或 msi 格式的附件并排除嵌入式版、ARM版、和网络版安装包。使用一个字典keep保存Python各个版本中的最高小版本号遍历所有版本号并不断更新最大值即可得到Python各版本的最高版本号。按照最高版本号取出符合条件的下载地址。打印输出匹配版本号和下载链接。
下载的事情就交给更专业的软件吧比如迅雷什么的。
三、下载地址
2023年11月26日运行结果可以使用迅雷下载 https://www.python.org/ftp/python/2.0.1/Python-2.0.1.exe https://www.python.org/ftp/python/2.1.3/Python-2.1.3.exe https://www.python.org/ftp/python/2.2.3/Python-2.2.3.exe https://www.python.org/ftp/python/2.3.5/Python-2.3.5.exe https://www.python.org/ftp/python/2.4.4/python-2.4.4.msi https://www.python.org/ftp/python/2.5.4/python-2.5.4.amd64.msi https://www.python.org/ftp/python/2.5.4/python-2.5.4.msi https://www.python.org/ftp/python/2.6.6/python-2.6.6.amd64.msi https://www.python.org/ftp/python/2.6.6/python-2.6.6.msi https://www.python.org/ftp/python/2.7.18/python-2.7.18.amd64.msi https://www.python.org/ftp/python/2.7.18/python-2.7.18.msi https://www.python.org/ftp/python/3.0.1/python-3.0.1.amd64.msi https://www.python.org/ftp/python/3.0.1/python-3.0.1.msi https://www.python.org/ftp/python/3.1.4/python-3.1.4.amd64.msi https://www.python.org/ftp/python/3.1.4/python-3.1.4.msi https://www.python.org/ftp/python/3.2.5/python-3.2.5.amd64.msi https://www.python.org/ftp/python/3.2.5/python-3.2.5.msi https://www.python.org/ftp/python/3.3.5/python-3.3.5rc1.amd64.msi https://www.python.org/ftp/python/3.3.5/python-3.3.5rc1.msi https://www.python.org/ftp/python/3.4.4/python-3.4.4.amd64.msi https://www.python.org/ftp/python/3.4.4/python-3.4.4.msi https://www.python.org/ftp/python/3.5.4/python-3.5.4-amd64.exe https://www.python.org/ftp/python/3.5.4/python-3.5.4.exe https://www.python.org/ftp/python/3.6.8/python-3.6.8-amd64.exe https://www.python.org/ftp/python/3.6.8/python-3.6.8.exe https://www.python.org/ftp/python/3.7.9/python-3.7.9-amd64.exe https://www.python.org/ftp/python/3.7.9/python-3.7.9.exe https://www.python.org/ftp/python/3.8.10/python-3.8.10-amd64.exe https://www.python.org/ftp/python/3.8.10/python-3.8.10.exe https://www.python.org/ftp/python/3.9.13/python-3.9.13-amd64.exe https://www.python.org/ftp/python/3.9.13/python-3.9.13.exe https://www.python.org/ftp/python/3.10.11/python-3.10.11-amd64.exe https://www.python.org/ftp/python/3.10.11/python-3.10.11.exe https://www.python.org/ftp/python/3.11.6/python-3.11.6-amd64.exe https://www.python.org/ftp/python/3.11.6/python-3.11.6.exe https://www.python.org/ftp/python/3.12.0/python-3.12.0-amd64.exe https://www.python.org/ftp/python/3.12.0/python-3.12.0.exe https://www.python.org/ftp/python/3.13.0/python-3.13.0a2-amd64.exe https://www.python.org/ftp/python/3.13.0/python-3.13.0a2.exe
