One way to generate column values using row index values in pandas is to use the .apply() method along with a lambda function.For example, if you have a DataFrame df with index values as integers, you can create a new column by applying a lambda function that uses the row index value.Here's an example code snippet:
import pandas as pd
# Creating a sample DataFrame
data = {'A': [10, 20, 30, 40],
'B': [50, 60, 70, 80]}
df = pd.
