Did you know a Hexagon can be constructed using the angle pi/3 a lot of times? This is because a hexagon is made of 6 triangles with equal side length - the radius of the hexagon. The inner angles of these triangles is pi/3. Using this information and the trigonometric functions sin and cos can be used to draw such a picture.
Did you know that 355/113 is an extremely close approximation of π? It’s accurate to the first 6 decimal places.
That’s accurate enough for most everyday uses except the most demanding scientific and engineering purposes.
Why should i use that instead of math.pi?
I missed the comment that said you should. Did they delete it?
You’re right. But as the other commenter suggested, if you’re on an embedded system or otherwise limited system, or even using another language missing certain constants and/or functions, it’s a good thing to know.
You could also just pull the constant from memory, assuming you have the brain memory space that I apparently have…

If you’re using an embedded version of Python that’s missing the
mathmodule. Because somebody couldn’t be bothered to fix the floating point math in C for platforms that don’t have an FPU 🤷
