Question

def all_gt(nums, n):
    i = []
    for c in nums:
        if c > n:
            i += c
    return i

This is the code that i used and ‘i’ is supposed to return the value in nums larger than n.
But mine returns nothing inside the bracket. E.g.,

all_gt([1,2,3,4], 2) => [3,4]

Anyone knows how to fix?
Thanks

Answer 1

You declared i to be a list, so you need to append to it instead of adding.

def all_gt(nums, n):
    i = []
    for c in nums:
        if c > n:
            i.append(c)  ## <----- note this
    return i

Alternatively, you could have done this:

            i += [c]

in place of the append.
