Input Validation Tutorial for Python
In this video I'll be covering the try except logic in python. I will be using the templates discussed in our previous videos but don't worry, these concepts can be demonstrated on their own! I'll leave a copy paste template below (as usual).
The Try except logic can be used for may things; however, I seem to use it most for input validation. In my work and personal life, I use this small but effective logic structure as a soft guide for anyone else trying to run my code.
There are other uses as well; the except clause can be modified for greater error reporting.
Challenge:
Next time you're troubleshooting code, try putting sections of it in a try except clause BUT modify the except clause so that it reads as the following:
except Exception as exception:
print(exception)
This will give you a better explanation of what is breaking in your code an you can quickly narrow down your mistakes.
===============================================
global var1
Validation
validation2 = True
while validation2:
try:
var1 = input()
validation2 = False
except:
validation2 = True
==============================================
