Python's contextlib is a HIDDEN GEM

The purpose of contextlib is fairly evident by the name (unless you've never heard of context managers), but it has some really cool tools that I wanted to share! Plus, there's a really neat decorator trick you can achieve with it too!

I had no idea `supress` existed. I made my own, and called it `ignored`. I guess it's a quick enough refactor...

[@MaxShapira2real]

Awesome stuff! 🚀

[@spectrapulse2104]

ah yes I was waiting for just this topic

[@JohnMitchellCalif]

[@Carberra]

Thank you!

[@collegeinvestor7095]

The terminal info of what branch and py version is neat, have you done a video on that?

[@Carberra]

I have! It's in the description.

[@JorgeLuis-ts6qp]

Es una gem tan hidden que está descrita en la documentación.

[@user-jg6dv2be2x]

This theme looks cool, what is it name?

[@Carberra]

I did a video on it linked in the description 😄

[@Daniel_Zhu_a6f]

nobody would have needed this stuff, would they just expose a local `goto` or make a `defer` keyword.

The "contextmanager" module is by far the most useful amongst the others.
It saves a lot of duck-typing compared to the traditional way of coding decorators.

[@vasiliigulevich9202]

Do you want to say "traditional way of coding context managers"?
