In this Python tutorial you’ll learn how to transform rows and columns in a pandas DataFrame to a list object.

Setting up the Example

import pandas as pd                       # Import pandas library to Python
my_df = pd.DataFrame({'A':range(2, 8),    # Construct pandas DataFrame
                      'B':['x', 'y', 'y', 'y', 'x', 'x'],
                      'C':range(1, 7)})
#    A  B  C
