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!

[@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❤!!!

[@sg8581]

Great videos, thanks a ton!

[@khaledelhoushi8834]

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

[@edselnarvaez9667]

Punit you are the best thanks a lot !

[@AbdulrahmanMuttakaJunju]

really interesting videos. however am having challenge solving a problem related to tuple, can you be of help?

[@SANGITA_SINGH1981]

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

[@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.

[@westonholmes9503]

These videos are great

[@georg101]

I am waiting for more!

[@kiran12314]

Classes are very easy to understand

Great videos, keep it up!!!

[@ohjinyoung4931]

Very good!

[@srhrithik5259]

Thank you programiz

[@mateenbutt3180]

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

[@kapibara2440]

Super video, thank you❤

[@ensonev8768]

Awesome. Keep going

[@ahmedyousif4782]

why the sound changed?

[@gabrielladangler1722]

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

[@shankarsai2067]

Why don't we have a live interaction session with Punit sir????

[@theonlymaster9374]

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

[@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

[@favourudoh753]

amazing!!

[@GiulioVonKerman]

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

[@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)

[@harish0000]

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

[@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.

[@majidalich2947]

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

[@sureshvarthya2250]

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

[@saravanaakavi2376]

will you make a video as per viewer request?

[@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)

[@EmereEmmanuel]

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

[@shadoestorme]

thank you!

[@ahmedaltaf12131]

thank you so much omg

[@cadribopraiseoyo5636]

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

[@mohammadabdullahaalforhad1375]

Thanks

[@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

[@praveenasurya3211]

can you add subtitles too sir?

[@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

[@karanbirsingh5924]

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

[@kushal-shaw-pvt]

Sir please teach tkinter

[@harshad9203]

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

[@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

[@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
