In this lecture, we will learn:
- Loops in Python language
- What is the use of loops?
- While loop and its implementation
- Syntax of the while loop
- Nested while loops in python
- What is the 'end' parameter in python?
#1
- We can execute a statement multiple times, by using the loops.
- There are two types of a loop:
1. For loop
2. While loop
- In the while loop, we need a counter to count the number of times, a statement can be executed.
- We also have to put a condition in a while loop to repeat a statement until the given condition is satisfied.
- The while Loop. With the while loop, we can execute a set of statements as long as a condition is true.
- When the condition becomes false, the line immediately after the loop in the program is executed.
- The value of the counter will increase or decrease until the condition gets false.
#2
- Syntax of the while loop:-
counter variable
while (condition):
statements;
incrementation/ decrementation
- So, there must be three things in a while loop:-
1. Initialization
2. Condition
3. Increment / Decrement
- Nested while loops can also be used in Python.
- Nested while loop simply means that a loop inside another loop.
#3
- To print the values in the same, we use (end=" "). The value will not come in the new line after using it.
- Passing the whitespace to the end parameter (end=' ') indicates that the end character has to be identified by whitespace and not a new line.

"it's not difficult, it's just unfamiliar"
I absolutely love this quote and plan on stealing it for so many things. :)
Also I'll recommend this playlist and give you credit
seriously dude ..i just love that quote and no doubt he is the best teacher to learn programming from.

Thank you so much for putting this together and walking through every step! This is so helpful for learning and really coming to understand how loops work in a programming mindset. I'm going to rewatch it again and again until I memorize this ha!
Dude, Debugging saved my life. I wasn't using it until I watched your videos and now I can see how useful it is.
Thank you so much
Crct bro
Yeah bro, exactly my thoughts
if i use debug its debuging venv how to resolve it ?
Me too
Anyone know how to use debugging function in the same way that he does on VSCode ?
I love this channel...
Edureka and Telusko are 2 channels doing more for the students than the education system itself!
Keep growing Sir
"It is not difficult, it is just unfamiliar". This is the quote of the year. Learning any new thing can be viewed from this angle. Thank you. 😊
I must say , being a new person to learn programming language, i am having so much of interest and fun for watching your videos, the way you are teaching is marvelous. Thank you so much for making easy task for us.
to be honest, you are really a great teacher and a wonderful programmer
downloaded many python courses from different sites , couldn't grasp them very well,this helped
thanks sir
subscribed :)
super sir ! i was taught while loop in C in class 11th, 30 years back, the looping now u have explained is marvelous ! Great ! God Bless You !
I really enjoyed his way of teaching and the way he explains the concept is just amazing 👍👍👍👍
Python tutorial is very good and you explained it in a detailed step by step manner. Thank you sir.
1st question:
i=1
while i
Why i=i+1 twice?
Thank u
@@standman007 cause if condition fails it doesn't do anything
Thanks for sharing this. I didn't know how to exclude numbers that are divisible by 3 and 5 from the code.
a = 1
while a < 101:
if a % 3 and a % 5 != 0:
print(a)
a = a + 1
thank you for the logic. instead of that we can directly assign the increment under the while statement.
Please correct me anyone, if I'm wrong
Hello Telusko , I am studying in one of the best university for data science and they gave introduction of python loop which i found it difficult to understand even asking them to explain twice but your 15 mins video made it very simple . Really your amazing and thank you so much .
In which university had you studied?
I was not able to understand this concept and found myself as a fresher to this concept, I want to say thank you for making these simple videos so as to make it more "familiar" and "clear" to us and that too in an intresting way🥰
After searching so many channels I found your channel for pythod ..
Now my search end here ..
I must say ur python playlist is best on TH-cam
I was finding a channel for Python learning from basics and then I got this channel (y).

Exceptionally best you are Naveen.
I have never seen in my whole life, a person teaching better than this for if else,while loop explanation...Kudos bro for great job!!
i dont generally comment in youtube videos even if i like them. But Sir your videos are truly a class apart. I mean its so simple and precise! Got just exactly what i needed. I hope you keep on releasing more videos.
I love your series, you get into details that other teachers take for granted

"or" takes either one condition is true
Eg: if number is 3
checks 3%3 !=0 - false

Then it will print 3 also

mind-blowing stuff .....learning python made so easy...Thanks Navin!
Code for # pattern:
r=int(input("Enter the number of Row(s): "))
c=int(input("Enter the number of Column(s): "))
i=1
while i
we can make it for any symbol:
r = int(input("Enter the No of rows: "))
c = int(input("Enter the No of Columns: "))
s = input("Enter the Symbol for the pattern: ")
i=1
while i
You can use this for the spaces
r = int(input("Enter the number of Row(s): "))
c = int(input("Enter the number of Column(s): "))
s = input("Enter the Symbol for the pattern: ")
i = 1
while i
sir love u,, ur excitement in coding makes me excited too
really appreciate this video, i'm doing a python course and you just made it easier! thank you!
very nice explanation and due to u i can now learn the language PYTHON SO fast as i had not thougth .
That was one of the best programming explanations. I wish everyone did tutorials like this.
The most amazing teacher!
the way you break down the loops is just awesome
sir firstly the debugging concept is very defficult for me ....but now it's very easy becoz of u....so thank u so much sir for this....really u r too good.

Dear@@mohammedsaad364 ,
Finally found such a comment.
I have a similar doubt ; can the code (for displaying numbers from 1 to 100 skipping numbers divisible by 3 and 5) be programmed with using 'nested while' loop only..?
But out of all the comments neither have I found help by Naveen Sir (Telusko's creator) nor a program that uses nested loop without the help of 'if', 'for', etc.
just because of this मैं समझा भी नहीं और पापा (जो मदद दे रहे थे, जो मैंने इंकारकर दिया) से डाँट भी मिल गया।

Thanks you very much for this video ,you really helped me and now I understand while loops better, its is very much appreciated.
The way you teach is speechless........ Never before ever after classes.. Superb ❤thanks a lot sir😊
I had doubt first but after watching the video it's now familiar to me.Thanks Navin sir.
Thanks a lot sir.. It really helped me alot...
I need to call you:
thanks! i just started learning python 2 days ago with the help of my cousin who knows python. He hasn't taught me loops yet... This video really helped.😁
The thing you said at the end really motivated me!
This is not difficult.......
This is just unfamiliar......🔥👍

0:55 but why you want to print telusko 1000 times thats called an alien thing. XD
just kidding sir you are the best teacher i have ever got on youtube : )
Awesome.. This inner for/while loop understood last week only while exporting Array list of values in to Excel workbook by debugging.. You nailed it.. 😘😘😘😘
I like the way you say "bye" at the end of each tutorial.
Sir upload more programming videos with logic building concepts please
Thank you

Thanks, I was super confused in my google Coursera course and this really helped.

Great method of teaching, At first I thought "how can a person learn coding from youtube". But now after watching your video @NaveenReddy sir its very easy and interesting to learn python. Even after going to physical classes I feel that your videos are enough to learn python
hi!! actually i had subscribed udemy website for learning python. i had lots and lots of doubts after seeing that videos . but after seeing your stuffs my doubts are cleared.. thanks for making these videos for us.. want to learn more from you.
sir, I like clear explanation of while loop, but could you make more video about while loop with different examples
There is barely nothing more about the topic, While loops are just like that. As he said at the end of the video, you just need practise
