I need to create a Dataframe after iterating through a nested list. I have 6 values that I would like mapped to a column in a Dataframe

You could use list of dicts to create DataFrame.

Store dict for every needed row and create DataFrame from stored rows:

import pandas as pd

frame_rows = []  # List to store dicts
for x in message:
    if len(x[15][0][0][0]) == 0:
        row_data = {
            'a': x[72][0],
            'b': x[15][0],
            'c': x[17][0],
            'd': x[19][0],
            'e': x[73][0],
            'f': x[71][0],
        }
        frame_rows.append(row_data)

df = pd.DataFrame(frame_rows)  # Create dataframe
print(df.head())
