Code Club – testing input
Once you have code working nicely, it is a good idea to add in error checking so that when asking for user input, what is put in to the program matches what is required.
We can ask a user for a numerical value so we know how many times to repeat the loop. How do we test for this.
letter = rawinput(“Enter your name “) i = letter.isalpha() while i != True: print(“Input MUST use letters”) letter = rawinput(“Name “) i = letter.isalpha() print letter
In this example, the user is asked to enter their name, this is stored and checked that is is actually a alphabetical character a-z or A-Z.
