In this Lesson, we create Program Code to check that a User or Player can only enter positive whole number integer values that are also in the correct number range.
We then go back to our Previous "Number Guessing Game" Project and add this same code so that Player's cannot crash the Program by entering text data, or waste Guesses by entering Numbers which are clearly out of range.
In this Input Number Validation Lesson we specifically learn the following Python Skills.
There are PDF Downloads for this lesson (see later below) which give a Lesson Introduction and Overview, followed by detailed Step by Step Instructions for completing the Lesson.
If you are a Teacher or Instructor then click the DOWNLOADS link below and get the lesson materials for your students.
The Downloads are critically important if your school or institution blocks or discourages YouTube Videos.
The Lesson can be fully completed using the Download Guides without watching the Video.
Give the Overview and Step by Step Guide PDFs to your students and we think you will find that some of them will "get it" very quickly.
The other students will greatly benefit from watching the video for this lesson which goes through everything in full detail slowly with step by step with repetition of examples.
Or simply use the Downloads to do your own in class Presentation and Lesson on Python Validation of Input for the Previous Lesson Number Guessing Game.
Because we are a slow talker, make sure students use the YouTube Player Bar Tools Cog to set the speed to 1.5x or even 1.75x
Note that the example Lesson Images shown on this web page are basic Printscreens, whereas the actual original Images are of perfect clarity and quality in both the downloadable PDF Guide and Word Document for this lesson.

Watch the following YouTube Video Tutorial about Making the Input Number Validation.
USE THE YOU TUBE PLAYER TOOLS COG TO WATCH THE VIDEO AT 1.5X OR EVEN 1.75X SPEED.
We highly recommend you use the RESOURCE MATERIALS available below
to follow along step by step with the Tutorial Video.
The YouTube Video is free to watch as many times as you want, and the Lesson Build Guide including all required Images and full program code listing(s) are available at a small cost which can be paid for and downloaded using PayPal.
Before purchasing and downloading the following resources, check first with your Teacher or Instructor, as they may already have copies of these documents to give to you.
Our Programming Learning Modules are designed for complete beginners, and they have been extensively trialled with High School students learning Programming for the first time. They have a proven track record of being able to get everyone up and running with Python - the world's most popular Beginner Programmer's language.
We highly recommend using the Step by Step Summary Guide as well as the other support materials to maximise learning outcomes.
Our students have found the Summary Guide to be far more useful than re-watching the Video, when it comes time for them to apply their newly acquired skills to Application Build tasks.
Prices for the Resource Package including the Guide, Images, Form Design, and full Program Code Listings are:
A Single Computer Licence for Personal Use is $AUD 1.93 (Approx $US 1.30).
A Site Licence for Business or Education Training for up to 30 people is $AUD 3.83 (Approx $US 2.60).
Licence Documentation will be included in your Downloads.

One known issue is that if you PayPal buy using Microsoft Edge, it often displays prices with A's around them like: A$1.93A.
The Edge purchase will work okay, but it is probably best to do Pay Pal purchases using Google Chrome as your browser.
