Python: Arrays, Lists, and List Builder

The List data type in Python allows you to store several values together. Lists are ordered and can hold duplicate values.
Lists are also known as Arrays or Vectors.
Learn how to define lists, access individual elements, alter them, and use list-builder notation to construct lists mathematically. We will use IDLE to define lists and see their elements.

Barry Brown, I have just came across your video and after following it for a few minutes, I really felt connected to your way of teaching. I am learning Python right now to use it later in my script writing skills (I am a linux Certified). Have you published any book (Python)?

[@AdventureXuk]

Can I just this is a fantastic tutorial on Arrays. I am teaching programming to my students at secondary school and your video is extremely useful for students to visit at a later date when they are not in the classroom. Please keep them coming!

[@jason.lackey]

You've got a gift for teaching. I hope you follow through with that. I'd like to see more videos.

Thank you for the clear, concise explanations!

[@JordanMetroidManiac]

Thanks. I never realized how awesome Python was until I saw "[x for x in range... if x...]" It's too simple! And it's like coding backwards. Lol

[x for x in range(2,21) if x % 2 == 0] == x for x in range(2,21,2) The third parameter of range is the skip operator

how do you accept values of matrix from user?

[@MicahTurnerMusic]

good stuff. just one thing... strings are already iterable. you can do [ord(x) for x in hi]
