Python Tutorial: A Comprehensive Guide to Cumulative Percentage Pandas
Python is a popular programming language used for a variety of applications. Pandas is one of the many libraries available for Python, and it is used for data analysis and manipulation. Pandas has many functions and methods for working with and manipulating data. One of these functions is the cumulative percentage calculation. This tutorial will explain how to calculate cumulative percentages in Pandas and provide an example.
Calculating Cumulative Percentages
The cumulative percentage is a calculation that shows the percentage of a total that has been reached at a given point. For example, if a total of 100 items are to be sold and 30 items have already been sold, the cumulative percentage is 30%. The cumulative percentage calculation is used in a variety of fields, including finance, economics, and business.
Pandas Functions for Cumulative Percentages
Pandas has two functions that are used to calculate cumulative percentages. The first is the cumsum () function, which calculates the cumulative sum of a series. The second is the pct_change () function, which calculates the percentage change of a series. Both of these functions can be used to calculate cumulative percentages.
Syntax for Cumulative Percentages in Pandas
The syntax for calculating cumulative percentages in Pandas is as follows:pct_change = df['column_name'].pct_change()cum_pct_change = pct_change.cumsum()In this syntax, ‘column_name’ is the name of the column in the data frame that contains the data for which the cumulative percentage is being calculated. The first line of code calculates the percentage change of the column, and the second line calculates the cumulative percentage.
Example of Cumulative Percentages in Pandas
To illustrate the calculation of cumulative percentages in Pandas, consider the following data frame:import pandas as pddf = pd.DataFrame({'sales': [10, 15, 20, 25, 30]})To calculate the cumulative percentage of the sales column in this data frame, the following syntax can be used:pct_change = df['sales'].pct_change()cum_pct_change = pct_change.cumsum()The result of this calculation is as follows:0 NaN1 0.52 0.53 0.54 0.5Name: sales, dtype: float64The result shows that the cumulative percentage of the sales column is 50%.
In this tutorial, we have learned how to calculate cumulative percentages in Pandas using the cumsum () and pct_change () functions. We have also seen an example of how to calculate the cumulative percentage of a series. Finally, we have also discussed the syntax for calculating cumulative percentages in Pandas.
Suggestion to Improve Coding Skill about Python Programming
To improve coding skill about Python programming related to Pandas, it is important to practice. Writing code and trying out different methods is the best way to learn. Additionally, it is important to keep up to date with the latest versions of Pandas and Python. Finally, reading tutorials and articles is also a great way to stay up to date and learn new techniques.
