pyref.dev is a fast, convenient way to access Python reference docs.

It allows you to quickly jump to the official documentation for Python standard library modules and popular packages by using a simple URL pattern:

https://pyref.dev/<fully.qualified.symbol.name>

You can also search for symbols using:

https://pyref.dev/is?symbol=<SYMBOL>

And if you are feeling lucky, ask it to redirect to the first result:

https://pyref.dev/is?lucky=true&symbol=<SYMBOL>

Lastly, you can pip install pyrefdev and run the pyrefdev CLI tool.

• pyref.dev/json
• pyref.dev/pathlib.Path
• pyref.dev/datetime.datetime.strftime
• pyref.dev/numpy.array

See pyref.dev for the list of supported packages.

For most of the cases, they are case-insensitive. However, for symbols like typing.final and typing.Final, you need to access them with the correct case.
