The function below tries to read a whole number (i.e., an integer) from the user and return it as an integer to its caller. This works great as long as what the the user types is a whole number. If the user types a non-integer number of a collection of letters, this code will fail when it tries to convert it to an integer. Fix this code so that it returns None instead of raising an exception. Do this with try/except blocks.

MrRoyal

The function illustrates the use of exceptions in programs.

Exceptions are used to prevent programs from failing

The function in Python, where comments are used to explain each line is as follows:

#This defines the function

def getInput():

   #This gets input from the user

   intINput = input('Number: ')

   #This opens the try block

   try:

       #This returns the integer input

       return int(intINput)

   #If the input is not an integer

   except:

       #This returns None

       return None
