How to Calculate a Percentage in Python

Python is a powerful language that can perform many mathematical operations. Calculating percentages is a common task in programming, and Python makes it easy to do so. In this guide, we will walk you through the steps to calculate a percentage in Python.

Step 1: Define Variables

To calculate a percentage, you need to define two variables: the numerator and the denominator. The numerator is the value you want to calculate the percentage of, and the denominator is the total value. For example, if you want to calculate what percentage of 50 is 10, you would define the variables as follows:

numerator = 10
denominator = 50

Step 2: Calculate the Percentage

Once you have defined the variables, you can calculate the percentage using the following formula:

percentage = (numerator / denominator) * 100

To continue with the example from step 1, you would calculate the percentage as follows:

percentage = (10 / 50) * 100

This would result in a percentage of 20%.

Step 3: Print the Result

The final step is to print the result. You can do this using the `print()` function. For example:

print("The percentage is:", percentage)

This would output the following:

The percentage is: 20.0

Conclusion

Calculating percentages in Python is a straightforward process. By defining the numerator and denominator variables and using the percentage formula, you can quickly calculate the percentage of any value.
