This URL (but without the trailing slash) also serves as a Python index API entry point (simple HTML index): You can install the latest aiocoap using:
$ pip install --extra-index-url https://aiocoap.codeberg.page/aiocoap 'aiocoap[all]'
or in Pyodide (for which this index also contains some additional binary dependencies in the right versions):
>>> await micropip.install("aiocoap[all]", index_urls=["https://aiocoap.codeberg.page/aiocoap", "https://pypi.org/simple"])
