Where I can find the explanation video for the task?

[@saiful_khalid]

We are so lucky that these videos are free. Thank you Programiz

[@rashedzaman990]

I have been lately watching a lot of videos but Punit, he truly stands out. His teaching method is awesome. Those who are struggling to understand Decorators in Python, I will strongly recommend them to watch Punit’s video on Decorators in Python.

[@pandathegeneral2426]

Im getting better at coding because of this channel THANK YOU SO MUCH im going to push myself until i become a game dev!

[@घटिया_कानून]

"guruji" clearest,easiest,simplest Its great asset for students to learn python

[@kawaiikina3618]

Thank you Punit and Programiz team's effort! Your videos are the best tutorials I have come across which provide clear explanation on the code structures and are sooooo easy to follow!!

[@घटिया_कानून]

The best

[@hadeerrashad5486]

This is the BEST video I have ever watched that explained the concepts perfectly.

[@danielakoyleek3757]

My guy! explicit teacher. Cheers from South Sudan❤!!!

[@beastashwin1923]

I can pass my test now thanks to you

[@ganneruvaramroshinichitti5407]

thankyou sir .its really simply more explanative...

[@khaledelhoushi8834]

You can also call the length function on slicing. You can do it like this print(len(languages[0:3])).

[@daviddavila8289]

12:15 Punit, why is the item “JavaScript” printed in a different color?

[@AbdulrahmanMuttakaJunju]

1. True 2. ['Hello', 'Hi', 'java', True] Traceback (most recent call last): File "", line 7, in TypeError: 'tuple' object does not support item assignment >

[@OptimusPrime-vy8vy]

This is really well done thank you!

[@sg8581]

Great videos, thanks a ton!

[@stefmyt5062]

Amazing video, sir! Very useful!

[@mateenbutt3180]

hi, is it possible using .insert() on list, we treat list or tuple we want to add as like .extend() treats ?

[@BalaKrishnan-qk2zu]

This video is really helpful. Thanks a lot

[@saurav2409]

Thank u so, to this precised n to the point lecture ... 🥺

[@srhrithik5259]

Thank you programiz

[@lakshanj.kumara7648]

mixed_list=["hello",-34,"java",True] print("1.",mixed_list[-1]) mixed_list[1]="Hi" print("2.",mixed_list) mixed_tuple=(1,3,4,5) print("3.",mixed_tuple)

[@srhrithik5259]

Thanks a lot 🤗🤗

[@nriezedichisom1676]

Videos are perfect

[@mohammedumair2968]

Good explanation sir 👏ossom Sir please make videos on *Data structure* sir please....

[@jeetkanse9855]

Walla habibi

[@adityagupta8950]

sir if we want to change 2nd and last element of list at once then what we will use?.I tried this but its results in reducing of size of list.the immediate element after the first index value is only there and rest of the elements in list is removed.

[@georg101]

I am waiting for more!

[@ohjinyoung4931]

Very good!

[@kapibara2440]

Super video, thank you❤

[@jitendrakasaudhan]

I really like all your video tutorials :) its simple , clean and clear :) BTW which tool do you use to edit/create these videos ? it looks great !! :) 👍

[@ahmedyousif4782]

why the sound changed?

[@mohammadabdullahaalforhad1375]

mixed_list = ('Hello!', -34,'java', True ) print('1.', mixed_list[0]) print('2.', mixed_list[1]) print('3.', mixed_list[2]) print('4.', mixed_list[3]) 1. Hello! 2. -34 3. java 4. True

[@westonholmes9503]

These videos are great

[@sandipansarkar9211]

great explanation

[@joyceadhiambo9977]

you can not change the elements of a tuple .hence this is the output mixed_list=['Hello',-34,'Java',True] mixed_list[1]='Hi' print('2.',mixed_list) print('1.',mixed_list[-1]) mixed_tuple=(1,3,4,5) mixed_tuple[1]=100 print('3.',mixed_tuple)

[@EmereEmmanuel]

My answer, hope i am doing well. 1. ["True"] 2. ["Hello", "Hi", "Java", "True"] 3. [1, 100, 4, 5]

[@ensonev8768]

Awesome. Keep going

[@lukedsouza7]

Thanks Great Job!

[@shankarsai2067]

[@kyrank.4321]

Great videos, keep it up!!!

[@GiulioVonKerman]

How can I change the position of an item in a list?

[@majidalich2947]

1. True 2. ['Hello', ' Hi', 'Java' , 'True' ] error : you cant use assignment operator in case of tuples 3. (1,3,4,5)

[@abdulquadiransari7476]

hey why the website went down . Why I am I unable to load the website?

[@rayar2323]

The website is up and running now

[@gabrielladangler1722]

Awesome videos! Looking forward to the next one! :)

[@harish0000]

Please also alow us to save our code in python compiler which is on your site

[@nithyanagendran5661]

Hello Sir, am having a doubt. I tried the following code . languages = ["Python","Java","Kotlin","C++"] languages[1:4] = ["Ruby","JS"] print(languages) and the result i got is : ------------------------------------- ['Python', 'Ruby', 'JS'] Why Kotlin didn't get printed ? what is wrong in this ?

[@tizestaxd]

because you wrote 1:4 it should be 1:3 look languages = ["Python","Java","Kotlin","C++"] languages[1:3] = ["Ruby","JS"] print(languages) result ['Python', 'Ruby', 'JS', 'C++'] I hope i helped u have a good day

[@sureshvarthya2250]

True ["Hello", "Hi", "Java", True] error it does not support for reassigning values into the tuple ,because it is immutable

[@favourudoh753]

amazing!!

[@mohammadabdullahaalforhad1375]

Thanks

[@cadribopraiseoyo5636]

Instructor what's your name? I like your tutorials a lot.

[@saravanaakavi2376]

will you make a video as per viewer request?

[@shadoestorme]

thank you!

[@Trazynn]

I understand that tuples are faster and make more efficient use of memory. But is that their only purpose? They do seem to require a lot more effort than just using a list.

[@programizstudios]

No, efficiency is not the primary reason to use tuples. In fact, the difference in efficiency is insignificant for 99.9% of the applications. The primary benefit of using tuples is that it helps us create less error-prone code. For example, Imagine you own an ecommerce site and you need to send emails to all the users regarding a new policy change. To do so, you decided to store all the emails (from the database) in a collection so that you can send the emails at once. In such cases, it's better to use tuples because we know for sure that these emails won't change throughout the execution of the program. And if the tuple is accidentally modified by you or other developers, we get an error (which is a good thing). This helps us create less buggy code. Also, using a tuple makes our code more readable. It's because when we see a tuple we know for sure that this data cannot be modified.

[@mateenbutt3180]

Why output are same? when I use .copy() method............. old_list = [[1, 2, 3], [4, 5, 6], [7, 8, 'a']] new_list = old_list.copy() old_list[2][2] = 10 print('Old List:', old_list) print('New List:', new_list) Output: Old List: [[1, 2, 3], [4, 5, 6], [7, 8, 10]] New List: [[1, 2, 3], [4, 5, 6], [7, 8, 10]]

[@AryanSingh-ju6wn]

with .copy() it must not be creating a new memory location but rather linking the previous one to the new variable

[@harshad9203]

1. 4 2. hello, hi, java, true 3. error

[@ahmedaltaf12131]

thank you so much omg

[@praveenasurya3211]

can you add subtitles too sir?

[@kushal-shaw-pvt]

Sir please teach tkinter

[@sunnyraut3243]

1.True 2.Hello Hii Java True 3.Error cannot assign value to tuple

[@ranjeet5806]

Answer of the Exercise : 1.True 2.Hello---- edit: it prints the whole list a error that you cant use assignment operator in case of tuples 3.1---- edit: it prints the whole tuple

Lets we have 3 reviewers and 4 movies......how to code this

[@kemaketseforkssebitiela3089]

❤i think i am going somewhere😅

[@relaxingmoments-787]

Your explaining style is very hard to understand You speak too fast You're writing your codes too fast And supporting logics aren't many And your coding font size is very small I am fully beginner, I can't catch it fast like others
