you don't need strip

But this code will produce an incorrect answer to arr = [1,1,1]. Or do I understand something wrong?

Note:
Your points are not included in the array of your class's points. Do not forget them when calculating the average score!

i wish import math had an average function

why you add 1?

thanks

class_points does not include your_points, so its length is the number of every other person in the class, which is why it does weirdly still makes sense to add exactly 1 more for the calculation, even though it won't change the calculation...

I think this solution is incorrect logically. The len function returns the length of the list meaning if there are 8 elements in the list, the len function returns 8. so adding 1 to it increases the length to 9 which is logically incorrect for the calculation of average with 8 elelment.
My view though

You run the risk of an error without it.

It was actually my solution, but then I read in the discussion that you don't have to add your points. However my mistake was in wrong placement of ">" :/

I too was going to add .strip() to my code to take the spaces off the ends. However when I tested with just .join() it passed so I left it out

I was going for this but couldn't figure out how to use the strip in the same line.
End up adding a second line with: return words.strip('')
:-(
