empty dataframes when appending series with for loop

Question

I need to append many series to a dataframe (averages_per_trip) but am getting empty dataframes each time. It doesn't even work once. What gives? (reference Is it possible to append Series to rows of DataFrame without making a list first?)

What is `averages` used in your code above? Another dataframe? — Mayank Porwal, Nov 08 '18 at 08:23
What you have in intput is not clear. Could you give us the head of all your input df so we can reproduce your issue ? — Charles R, Nov 08 '18 at 08:26

The problem is with the append function. It does not update the initial dataframe, you must:

df = df.append(stuff)
