Percentage Calculation Exercise Using Python

In this tutorial, you will learn how to calculate a percentage using Python. We will go through an exercise that involves formatting a decimal fraction as a percentage with no decimal places. This exercise is part of the Python Basics Exercises: Numbers and Math course.

Exercise Overview

You are almost at the finish line when it comes to formatting numbers in Python. In this final exercise, you’re going to format a decimal fraction as a percentage with no decimal places.

Code Solution

To solve this exercise, you can use the following Python code:

decimal_fraction = 0.456
percentage = decimal_fraction * 100
formatted_percentage = f"{percentage:.0f}%"
print(formatted_percentage)

Explanation

In the code above, we first define our decimal fraction as 0.456. We then calculate the percentage by multiplying the decimal fraction by 100. Next, we use f-strings to format the percentage with no decimal places using the :.0f format specifier.

When you run the code, it will output:

46%

This represents the decimal fraction 0.456 as a percentage with no decimal places.

Conclusion

In this tutorial, you learned how to calculate a percentage using Python. By going through this exercise, you practiced formatting a decimal fraction as a percentage with no decimal places. This exercise is a great way to reinforce your understanding of working with numbers and math in Python.
