# What does percent mean in Python?

198    Asked by ColemanGarvin in Python , Asked on Jul 18, 2024

I am currently engaged in a particular task that is related to developing a Python-based application that can process and analyze the sales data for a particular retail company. One of the requirements is to generate a report which shows the percentage increase in sales from one month to the next month. Additionally, the report should include a formatted summary for easy readability. To get this, I need to:-

Calculating the percentage increase in sales from January to February, given that the sales figures are: January - \$10,000 February- \$12,000 Format the summary string to display the sales figures and the percentage increase.

How should I use the percentage symbol in the Python programming language to calculate the percentage increase and format the summary string?

In the context of Python programming language, here are the appropriate approach given:-

Percentage calculation

The formula to calculate the percentage increase from January to February is :

``````            	ext{Percentage Increase} = left( rac{	ext{Sales in February} - 	ext{Sales in January}}{	ext{Sales in January}}
ight) 	imes 100``````

This formula would help you in computing the relative increase in the sales from January to February as a percentage.

String formatting

In the context of Python programming language, the percentage symbol is used for string formatting. It can be used to embed value into a string. For instance, %0.2f% value would format floating point numbers to two decimal places. You can also use the percentage symbol for formatted string, embedding multiple values into a template string.

Here is a Python-based coding given:-

``````# Sales figures
Sales_january = 10000
Sales_february = 12000
# Calculate the percentage increase
Percentage_increase = ((sales_february – sales_january) / sales_january) * 100
# Format the summary string
Summary = (
“Sales in January: \$%d, Sales in February: \$%d, Percentage Increase: %.2f%%”
% (sales_january, sales_february, percentage_increase)
)
# Print the summary
Print(summary)``````

Explanation of the code:-

Sales figures

These are the sales amounts for January and February.

Percentage increase calculations

The formula would calculate the percentage increase by finding the difference between February and January sales, dividing by the January sales, and then multiple by 100.

Formatting the summary string

The summary string would use the percentage operator to format the output.

In this way, if you follow the above formula and coding, you can easily get the output that you want, showing the percentage increase in sales from January to February.
