Python Arrays and Lists plus Using Arrays for Validation - Beginner Python Lesson Learn Python Fast
Показать описание
Subscribe to our Channel to get regular Video Lessons in Python Programming.
Because we are a slow talker, we recommend you use the YouTube "Tools Cog" on the player bar to watch the video at a speed of 1.5x or even 1.75x.
In this Lesson, we learn about Python Storage Arrays and Lists.
We then do User Input Validation by setting up a list of the allowed valid input values in an Array.

You do not have to use PyScripter for our Course. All of the program code will run in Python 3.7 or higher.
So if you want to use other popular Python IDE’s like PyCharm or MU, that will be okay.
In this Python Lesson we will work on learning the following skills:
- How to set up an Array Storage Table of Data Items in a Python Program.
- How to use the Python len( ) to count the Array items.
- How to Print out the contents of an Array using a While Loop and a For Loop.
- How to add additional items into an existing Array and output info about them.
- Knowing the difference between an “Array” and a Python “List” and when to use them.
- How to use a Python List to Make a Price List of Items and Print the Price List out.
- Doing Input Validation by setting up a list of the allowed input values in an Array.
- How to make a Membership Application program for people to join a special Club.
Using and Processing Storage Arrays is a critical part of programming in all computer languages.
It is vitally important to study and understand the Arrays program code, as well as the organisation structure of the program Validation using Arrays.
The learning here will be essential for future Python Programming Lessons we will be progressively adding to our Channel.

If you are a Teacher watching this video then click the downloads link and get all of the lesson materials for your students.
Give these resources to your students and we think you will find that some of them will "get it" very quickly. The other students need to watch this video which goes through everything in full detail slowly step by step with repetition of examples.
This is a detailed video, if you want to fast track learning, then just Download and quickly work through the PDF of Step by Step Instructions using the Link given further down below.
There is also an Introduction and Overview PDF document giving a set of Learning Objectives for the Lesson included in the Lesson Downloads.
Then for anything you do not fully understand in these two documents, simply use the Timeline Index below to go and watch the relevant section of Video explanation.
If you have the time it will be extremely beneficial to watch the entire video to maximize learning outcomes.
