Write a python program to find absolute value using function

1. Introduction

This blog post will guide you through creating a Python program to find the absolute value of a number using a function. The absolute value of a number is its distance from zero on the number line, regardless of direction. This example is a great way to understand how to write functions in Python and use built-in functions.

2. Program Steps

1. Define a function that takes a number as an argument.

2. Inside the function, use the built-in abs() function to find the absolute value of the number.

3. Return or print the absolute value.

3. Code Program


def find_absolute_value(number):
    # Step 2: Use abs() to find the absolute value
    absolute_value = abs(number)

    # Step 3: Return the absolute value
    return absolute_value

# Step 1: Define a number
num = -5
result = find_absolute_value(num)
print(f"The absolute value of {num} is {result}")

Output:

For the number -5, the output will be 5.

Explanation:

1. The function find_absolute_value is defined to take one parameter, number.

2. Inside the function, the built-in abs() function is used to calculate the absolute value of number. The abs() function returns the absolute value of any number it receives, regardless of whether it's positive or negative.

3. The absolute value calculated by abs() is then stored in the variable absolute_value and returned.

4. When the function is called with num = -5, it returns 5, which is the absolute value of -5.

This program effectively demonstrates the use of functions in Python to perform a specific task, in this case, calculating the absolute value of a given number.
