PYTHON — Show Percentage Solution in Python

The human spirit must prevail over technology. — Albert Einstein

In this tutorial, we’ll explore how to show a percentage in Python. When you divide two numbers, you can format the result as a percentage using the percent sign as the format specification. Let’s take a look at how to achieve this with Python code.

First, let’s consider the scenario where you divide 2 by 10, resulting in a floating-point number with one decimal digit. You can format this as a percentage using the following code:

result = 2 / 10
percentage = "{:.1%}".format(result)
print(percentage)  # Output: '20.0%'

In the code above, the "{:.1%}".format(result) specifies that the result should be formatted as a percentage with one decimal place.

If you prefer using f-strings, you can achieve the same result with the following code:

result = 2 / 10
percentage = f"{result:.1%}"
print(percentage)  # Output: '20.0%'

In this code snippet, the f"{result:.1%}" syntax is used to format the result as a percentage with one decimal place.

Now, let’s consider the scenario where you want to display the percentage without any decimal places. You can achieve this by adding a zero after the dot in the format specification. Below is an example:

result = 2 / 10
percentage = "{:.0%}".format(result)
print(percentage)  # Output: '20%'

Similarly, the same output can be achieved using f-strings:

result = 2 / 10
percentage = f"{result:.0%}"
print(percentage)  # Output: '20%'

By following the code examples provided, you can format a number as a percentage in Python. This can be useful when working with percentage-based calculations or when displaying data in a user-readable format.
