In this lecture we will learn:
- Recursion in Python
- How to call a function inside the same function?
- How to set the limit for recursion in Python?
- Use of sys library functions
- Why recursion is useful?

#1
- Recursion means calling a function from itself.
- To print a statement of a function multiple times, we can call a function inside the same function.
- By default, a function inside a function will execute infinite times.
- Maximum limit for recursion is 1000 in python, so it will give an error after exceeding its limit.
- Limit can also be changed by doing some customization.
- If a code goes into recursion without a condition and it goes to infinite times, then it may hang the system and that limit is set in python.
- We can also print the limit of recursion by using the function getrecursionlimit() available in the sys library.
- We can change the limit for a recursion by using the setrecursionlimit() function.
- We can set the limit to any number by providing it in the setrecursionlimit() method.
- We have to make the variable global to access it if it is defined outside the scope.
- Recursion is used to perform several tasks in many projects.

#2
- A complicated function can be split down into smaller sub-problems by using the recursion.
- Recursive functions make the code look simple and effective.

The best thing is that we get to learn from your silly mistakes also...And it's a Complement

[xMikochix]

Thank you for helping me out!! I cannot seem to understand recursion for the longest time

[Alberta_Farmer]

Seriously just the most helpful tutorials ever. In 40 videos you have passed the knowledge depth that I've seen taught in two introductory state university courses for computer science.

Sir Navin this video is awesome, I am just learning for the first time that you can increase the recursion limit of a function to be greater than 1000. Thankyou very much I really appreciate.

[lucifer]

Wow!! I never know a person can teach programs like this!!!

[kharlopena]

Thank you! You're the only person I've seen explain this in easy to understand terms!

[maheehossain]

Mate you're an absolute fucking legend, thanks for this

Anyone in 2020?


I started learning c++ five years ago, and I got bored. Now after watching 40 of your videos this is my first comment. I never knew programming could this fun. Learned and executed all your scripts til now, and I am grateful to you.

Since 1 month I have been watching ur classes sir tq a

[sunilkumarsamji]

Amazing information Navin Reddy. Helps beginners a lot. BTW in the above example on recursions. When the recursion limit is set to 2000. It prints 1996 times. Why is that? What happened other four iterations. Why they are not printed?

[rohit]

Your lectures are awesome ...simple and beautiful 😍 thank you so much

[shailusv]

Telugu vara???
super undi mee explaination....thank you so much for ur videos

[chitvilaskalal]

Amazing teacher i will found on the YouTube ❤

[hetvichudasama]

Thank you so much for this amazing tutorials 🙏🏻🙏🏻🙏🏻

[SwapnadeepMukherjee]

Tried with the value as follows:

*sys.setrecursionlimit(5000)*

The last value printed was:

*Hello 2416*

[anonymousja]

... I really...loved the way...of teaching....✌️🔥🖤

[poonamleekha]

I have no words to thank u because your python series is awesome. i belong to chemistry background from India and i only only watch your videos and learn it. if you have vidoes on practicing python coding, pls share because being a lay man we are not able to do that specially for the first time. thanks once again

[VANSHDUTTPATHAK]

my man explained recursion so easily thank you so much

[AmanAliJB]

really making this quarantine period fun and useful!
