Python question:
def arr(n):
list=[]
i = 0
if not n:
return ([])
else:
while i < n:
list.append(i)
i = i+1
return (list)

any suggestions on why im getting an error:
TypeError: arr() missing 1 required positional argument: 'n'
Could be a simple mistake, as I'm new to Python

there is a bunch of additional checks run when you make an 'attempt' - at 'test' it just checks the expected functions have been used, but it doesn't check the retured table values are matching the criteria, it does it at the 'attempt'

I actually did and it passed through. I would normally use REGEXP_EXTRACT if that wasn't postgre. The most common/simple solution is different though :)
