Google search results very often have links to Python 2 docs page. However, if you are programming in Python 3, switching to version 3 docs constantly may be pretty annoying. Same thing if you're not using the latest version of Python 3 and want to always see a specific version. This extension does that for you.

There's also a <a href="https://chrome.google.com/webstore/detail/py3redirect/codfjigcljdnlklcaopdciclmmdandig">Chrome version</a> available.
