Find Absolute Value
Compute the absolute value of a number without using the built-in abs() directly.
BeginnerTopic: Basic Python Programs
What You'll Learn
- Understanding absolute value conceptually
- Using simple conditionals to implement math rules
- Working with negative and positive numbers
Python Find Absolute Value Program
This program helps you to learn the fundamental structure and syntax of Python programming.
# Program to find the absolute value of a number
num = float(input("Enter a number: "))
if num < 0:
abs_value = -num
else:
abs_value = num
print("Absolute value of", num, "is", abs_value)Output
Enter a number: -7 Absolute value of -7.0 is 7.0
Step-by-Step Breakdown
- 1Read a number from the user.
- 2Check if it is negative.
- 3If negative, multiply by -1 to make it positive.
- 4Otherwise, keep it as is.
- 5Print the result.
Understanding Find Absolute Value
The absolute value of a number is its distance from zero on the number line.
•If num < 0 → abs(num) = -num
•Else → abs(num) = num
This shows how to reimplement a built-in idea using basic conditionals.
Note: To write and run Python programs, you need to set up the local environment on your computer. Refer to the complete article Setting up Python Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your Python programs.
