网址一：
https://pypi.org/search/?c=Programming+Language+%3A%3A+Python+%3A%3A+3
网址二：
https://pypi.org/project/qface-qtcpp/#files
这两个网站没有什么特别，唯一就是境外，建议你先建立科学的连接，然后访问
import requests
res = requests.get('https://pypi.org/search/?c=Programming+Language+%3A%3A+Python+%3A%3A+3')
res.encoding = 'utf-8'
print(res.text)
源代码太多了，我这里各贴出前100行
