Python Tutorial for Beginners 4: Lists, Tuples, and Sets

In this Python Beginner Tutorial, we will begin learning about Lists, Tuples, and Sets in Python. Lists and Tuples allow us to work with sequential data, and Sets allow us to work with unordered unique values. We will go over most of the methods, learn when to use which data type, and also the performance benefits of each type as well. Let’s get started.

De Kift says:

Thanks Corey, great tutorials! Very clearly layed out and nice presentation.

There’s one thing here that struck me: I’m not new to programming in general but the behavior in 21:28 ( _both_ lists changing) was quite shocking to me :-) I had a slight hunch what was happening there but still I had to look it up and found this: https://stackoverflow.com/questions/2612802/how-to-clone-or-copy-a-list (for all you guys out there who got confused).

npgatech says:

Hi Corey, love your tutorials but please explain **WHY** we need to use tuples vs. lists. Saying that use tuples when you need immutable values and use lists when you need mutable values is not sufficient. One of the things that irk me so much about every single tutorial, book, lesson on programming is no one fricking explains **why**. You did explain why when you were explaining sets – i.e. they are more efficient when doing certain operations (union, difference, intersection). Similarly, tuples are immutable, but they more efficient for lookup than lists. That is why you use tuples. Thanks for listening :-) You’re probably the best teacher on Python anywhere on the internet. Thank you!

Michelle wooltorton says:

Just started to learn Python this tutorial is easy to follow and has helped me to understand loads thank you so much.

Azhagu Nagappan says:

By far many Python tutorials are available in the internet,Like Coursera python courses, Udemy, Learning python the hard way, many other blogs and Vlogpresented by many individuals and companies, with all due respect to all the tutorials given by Corey Schafer is simple and to the point. Anyone willing to learn Python(programming) going through Corey Schafer’s tutorials will give you happiness. Thank you Schafer!.

Hi Corey! you are just awesome !!! great vidoes.
Could you please advise on these 2 lists –
my_list1 = [‘c’,’d’,’e’]
my_list2 = [‘a’,’b’]

How we can join them together so that final_list would be like this
final_list = [a’,’b’,’c’,’d’,’e’]

Ahmad Masih Ghani says:

your videos are just amazing for beginners, i am really thankful for your efforts .

Awaleh Houssein says:

You’ve done a great job, thank u so much.

Prateek Dave says:

How are List , Tuple and Sets implemented to be what they are ?

Jeef TechTips says:

This is not correct where you said if change one string in tuples also change the second string for second list. The reason it happens in your code is because your second list = to the first list.

Swarnabh Kashyap says:

Thank you Corey! You are awesome!

sandeep saradhi says:

Hello, I am really happy with the videos, thank you so much. I have a small question.When I perform enumerate on a list and print the original list it is only printing the last element in the list may I know why is that?

Vipul Rana says:

Awesome work, I had a question when I entered nums=[’99’,’11’,’0′,’9′] the output was [’99’, ‘9’, ’11’, ‘0’] for nums.sort(reverse=True) and [‘0′, ’11’, ‘9’, ’99’] for nums.sort()
