sorted() and lambda functions! solution in Clear category for Absolute Sorting by tigercat2000
def checkio(numbers_array):
# Use the normal python sorted() function to sort the users.
# We could use list.sort(), if there weren't tupples involved.
# The key parameter is a lambda function (an inline function)
# The lambda function tells the sorted() function to compare to the absolute values of each element, rather than the element itself.
numbers_array = sorted(numbers_array, key = lambda a: abs(a))
# Return the sorted array.
return numbers_array
#These "asserts" using only for self-checking and not necessary for auto-testing
