ahh... lemme cache my hello world program now

I just found out that the cache decorator was added in Python version 3.9, so those who are in a previous version have to use lru_cache instead.

You can increase the recursion limit using sys module

import sys
sys.setrecursionlimit(10**12)

Me: "How do I do caching in python... I bet there's a module for this."
NeuralNine: "yeah 'from functools import cache' "
Perfect video, it's rare that you get the exact answer you are looking for with a walk through right away. I love the future!

When caching is used in calculations like this the technique is often called 'memoization'. Also quite handy when writing a prime factor sieve. Love the channel. Long live human 2.0. Go SpaceX.

Thank you for this sir! (Watching from Philippines)

[Thokpower]

Actually learned so much from this. Decorators finally make sense and I found a way to speed up my python programs

[mohamedhabas]

More of this content please !!
actual real life use-full things
thank you for the hard-work

[akshatdodhiya]

Loved your intro music!





The video as well. You're awesome and unique as always :)

When recommendation is faster than notification

[rugmaable]

amazing video and content. Straight to the point.

[Manishdna]

This is awesome! Learned much about it!

[phinguyen]

this cache is similar to the idea of dynamic - save some part of the result

[MrRezhes]

Thank u, and is there anyway u could make a video on Cython, Numba, or any other library helping speed ups?

[gerokatseros]

my python 3.9 functools dont have @cache anymore i think, i get an error whereas @lru_cache works

[learntocode]

awesome toturial, thanks.
but can we know how the cache function acts or not, and can we write a normal function acts like a built-in cache function.

[rizkyagungshahputra]

I had already tried to import cache from functool in google colab but it got an error, do you know why this happens? So instead i import Cache from cache-decorator

[mr.lawliet]

When I saw it I just hoped that it wasn’t an april fools

[cagataydemirbas]

for me it isnt working. with cache and without cache always shows same time idk why

[GodbornNoven]

Caching data basically means you're decreasing the amount of calculations you need to do by optimizing the process through which the calculations are done.
But heres what im confused about.
Why does caching make it THAT much faster? Here you're decreasing the number of calculations u need to do by half (or is that more than half) so why is it so significantly faster
Found my answer. The decrease in calculations is significantly more than half.
The Fibonacci sequence is super unoptimized
