+Write a function named exactly "median" which receives a list of element as parameter and returns the median value of
+the list. The median is the value separating the higher half from the lower half of a data sample. If the list has an
+even number of elements, the function should return the average of the two middle elements. You should not modify the
+original list, but you can sort in a copy of the list.
+
+Example:
+median([1, 2, 3, 4, 5])     # returns: 3
+median([1, 2, 3, 4, 5, 6])  # returns: 3.5
+'''
+def median(numbers):
+    sortedNums = sorted(numbers)
+    length = len(sortedNums)
+    mid = length // 2
+    if length % 2 == 0: # even number-> avg of middle two
+        return (sortedNums[mid - 1] + sortedNums[mid]) / 2
+    else: # odd number-> middle element
+        return sortedNums[mid]
+
+print(median([1, 3, 2, 4, 5]))     # returns: 3
+print(median([1, 2, 3, 4, 5, 6]))  # returns: 3.5
