Identify Column Indices in pandas DataFrame in Python (Example Code)

import pandas as pd                                # Load pandas library

import pandas as pd # Load pandas library

my_df = pd.DataFrame({'A':[1, 2, 9, 2, 1, 2, 7],  # Construct example DataFrame
                      'B':[5, 3, 8, 7, 1, 9, 2],
                      'C':[8, 2, 5, 7, 1, 2, 6]})
