Finding median of list in Python

Question

How do you find the median of a list in Python? The list can be of any size and the numbers are not guaranteed to be in any particular order.

If the list contains an even number of elements, the function should return the average of the middle two.

Here are some examples (sorted for display purposes):

median([1]) == 1 

median([1, 1]) == 1 

median([1, 1, 2, 4]) == 1.5 

median([0, 2, 5, 6, 8, 9, 9]) == 6 

median([0, 0, 0, 0, 4, 4, 6, 8]) == 2

Answer 1

To find median of the list in Python you can use the below-mentioned code:-

def median(lst): 

quotient, remainder = divmod(len(lst), 2) 

if remainder: 

return sorted(lst)[quotient] 

return sum(sorted(lst)[quotient - 1:quotient + 1]) / 2.

Answer 2

Try using this:

l = [15, 18, 2, 36, 12, 78, 5, 6, 9]

sum(l) / float(len(l))
