IslandT: Find the maximum gap between the successive numbers in its sorted form from a Python list

Given a Python list consists of plus or minus numbers, we need to sort that list then find the maximum gap between the successive numbers in that list regarding of its sign.

For example,

maxGap ({-7,-42,-809,-14,-12}) ==> return (767)

Explanation:

The Maximum Gap after sorting the array is 767, The difference between | -809- (-42) | = 767.

def max_gap(numbers):

    numbers.sort()
    gap = []

    while(len(numbers) > 1):
        first = numbers.pop(0)
        second = numbers[0]
        gap.append(abs(second-first))
    
    return max(gap)

1. Sort the list in ascending order.
2. Create a full gap list in the while loop.
3. Return the maximum different.
