Add column to the end of Pandas DataFrame containing average of previous data

Question

I have a DataFrame ave_data that contains the following:

ave_data

Time        F7           F8            F9  
00:00:00    43.005593    -56.509746           


        

Answer 1

@LaangeHaare or anyone else who is curious, I just tested it and the copy part of the accepted answer seems unnecessary (maybe I am missing something...)

so you could simplify this with:

df['average'] = df.mean(numeric_only=True, axis=1)

I would have simply added this as a comment but don't have the reputation
