find longest subarray by sum

def max_length(s, k):
    current = []
    max_len = -1 # returns -1 if there is no subsequence that adds up to k.
    for i in s:
        current.append(i)
        while sum(current) > k: # Shrink the array from the left, until the sum is <= k.
           current = current[1:]
        if sum(current) == k:
            max_len = max(max_len, len(current))

    return max_len
