你可以在PyPI JSON API中找到这些。
发行版coloredlogs==15.0.1只提供了2个文件，一个sdist和一个universal wheel：

>>> resp = urllib3.request("GET", "https://pypi.org/pypi/coloredlogs/15.0.1/json")
>>> data = resp.json()
>>> len(data["urls"])
2
>>> for dist in data["urls"]:
...     print(dist["filename"])
... 
coloredlogs-15.0.1-py2.py3-none-any.whl
coloredlogs-15.0.1.tar.gz

字符串
这个包是pure Python源代码，不提供任何编译的扩展模块，所以一个通用的wheel就足够了。
但例如，对于问题中提到的cffi 1.16.0，有许多轮子可用，使用不同的platform compatibility tags构建：

>>> import urllib3
>>> resp = urllib3.request("GET", "https://pypi.org/pypi/cffi/1.16.0/json")
>>> data = resp.json()
>>> len(data["urls"])
52

型
实际的文件名：

>>> for dist in data["urls"]:
...     print(dist["filename"])
