Python Function: How to Write Error Logic

Image
Python is one of the top programming languages. Python does support Functions. While writing functions you also need to consider some errors. Those are called exceptions. I am explaining how to give error logic in a function of Python.



Exception-handling means to have logic for error scenarios. Writing exception I will show in a simple Function.

In this post I will give you syntax for writing function and exception. 
Here is my simpleFunction that multiplies two numbers.
Logic to write Function in Python to Multiply Two Numbers 
def product (num1,num2): prod=num1*num2 print( ' The product of the numbers is \t: '+str(prod)
Parameters used the Python Function
 The 'def' means you are defining function with a name of 'product'.In the parameters of 'product', you can see TWO variables. Those are to take input from the user for multiplication.prod=num1*num2. That means product of two numbers assigning to 'prod' variable. Python is dynamic language and you no ne…
