+def median(list):
+	list.sort() # The sort function of python
+	list_length = len(list)
+	if list_length%2==0:
+		return (list[int(list_length/2)-1] + list[int(list_length/2)])/2 # Mean of the middle two elements
+	else:
+		return list[int(list_length/2)] # The element in the middle

+median([1,2,3]) # 2
