Need help using python pandas module to create one column from subtracting other two columns

Certainly! Creating a new column in a Pandas DataFrame by subtracting values from other columns is a common operation. The pandas module in Python makes this task straightforward. In this tutorial, we'll go through the process step by step with a code example.
Before you start working with Pandas, you need to import the library. You can do this by using the following code:
For the sake of this tutorial, let's create a sample DataFrame with two columns (column_a and column_b):
Now, let's subtract column_b from column_a and create a new column called result_column:
This line of code subtracts the values in column_b from the corresponding values in column_a and stores the result in a new column called result_column.
You can print the DataFrame to see the result:
The output should look like this:
Here's the complete code:
Now, you've successfully created a new column (result_column) by subtracting values from two existing columns in a Pandas DataFrame. This process can be adapted to any similar scenario in your data analysis tasks.
