Working with tabular data exercise

[janash]

Exercise: "Calculate the average of each row of data. You don’t want to include the frame numbers in the average. Make a new list of the average of each row."

I think discarding the frame numbers in the exercise might be confusing for those following along. Since it's in an exercise, I can see it being something people might miss, as they might make new data instead of overwriting the variable, or skip the first column in another way.

For example, this was my solution:

avg_list = []

for row in data:
    avg_list.append(np.mean(row[1:]))

Here, I haven't discarded the frame numbers, so the following code block is different for me.

I see that other exercises build on this. The lesson might just need to include explicit instruction to discard the column with the frame number.

This has been fixed.
