Pandas DataFrame Abs Method

Introduction

In this lab, we will learn about the DataFrame.abs() method in the pandas library. This method is used to find the absolute value of each element in a DataFrame.

VM Tips

After the VM startup is done, click the top left corner to switch to the Notebook tab to access Jupyter Notebook for practice.

Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook.

If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.

Import the pandas library

First, we need to import the pandas library. This can be done using the following code:

import pandas as pd

(Note: This code should be executed before using any pandas functions or methods.)

Create a DataFrame

Next, we will create a DataFrame to work with. Here is an example of creating a DataFrame with some numeric values:

df = pd.DataFrame([[23, -85, -0.25],[2, -1.259, -85]], columns=['A', 'B', 'C'])

Use the abs() method

Now, let's use the abs() method to get the absolute value of each element in the DataFrame. The abs() method returns a new DataFrame with the absolute values. Here is an example:

df_abs = df.abs()

Print the original and absolute value DataFrames

Finally, let's print both the original DataFrame and the DataFrame with absolute values to see the difference. Here is an example:

print("-----Original DataFrame-----")
print(df)
print("-----DataFrame with Absolute Values-----")
print(df_abs)

Summary

In this lab, we learned about the DataFrame.abs() method in pandas. We used this method to find the absolute value of each element in a DataFrame. The abs() method is useful when working with numeric data and can help us analyze and manipulate the data effectively.
