pip包安装源地址查询及Biopython安装网络受阻解决方案咨询

Hey there, let's tackle your questions one by one.

By default, pip uses the official Python Package Index (PyPI) as its primary source for installing packages. The main endpoint it queries to find available packages is:

• https://pypi.org/simple/

Behind the scenes, once pip locates the package you want (like Biopython), it will download the actual installation files (wheels or source archives) from linked storage locations. The most common of these is:

• https://files.pythonhosted.org/

Given that your pip install biopython error stems from network blocking, here are the key URLs you need to ask your network admin to unblock:

• https://pypi.org/simple/: This is where pip checks for Biopython's availability and retrieves its download links
• https://files.pythonhosted.org/: This is the primary storage server hosting Biopython's installation files (wheels and source code packages)

In most standard installation scenarios, unblocking these two URLs should resolve your connection issues. If you encounter further problems later, you might need to check if any regional PyPI mirrors are being used, but these two are the core addresses for default pip setups.
