Find the median of a list of numbers

Sort the numbers of the list using list.sort() and find the median, which is either the middle element of the list if the list length is odd or the average of the two middle elements if the list length is even..

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
median([1,2,3,4]) # 2.5
