including how it can be stored and what types of operations we can perform. For example, we can write a program that squares num
ASHA 777 [7]

Answer:

The solution code is written in Python:

  1. def square(num):
  2.    if type(num).__name__ == 'int':
  3.        sq_num = num * num
  4.        return sq_num  
  5.    else:
  6.        return "Invalid input"
  7. print(square(5))
  8. print(square("Test"))

Explanation:

To ensure only certain type of operation can be applied on a input value, we can check the data type of the input value. For example, we define a function and name it as <em>square</em> which take one input number, <em>num </em>(Line 1).

Before the <em>num</em> can be squared, it goes through a validation mechanism in by setting an if condition (Line 2) to check if the data type of the input number is an integer,<em> int.</em> If so, the<em> num </em>will only be squared otherwise it return an error message (Line 6).

We can test our function by passing value of 5 and "Test" string. We will get program output:

25

Invalid input
