About Loop & Branch

Loop & Branch publishes practical tutorials for Python and web developers. Each page answers one concrete question, shows code that has been run on current library versions, and points to the official documentation for the details.

How tutorials are written

• Code samples are executed before publication; outputs shown on the page are real outputs.
• Version-specific behaviour is stated (for example urllib3 1.x versus 2.x).
• Pages are reviewed and updated when a library changes its API.

About this domain

Between 2021 and 2023 this domain hosted a different site, which republished posts from other developer blogs. Loop & Branch is a new, independent publication with no connection to that site or to the authors it republished; none of its texts are reused here.
