Using python

Statisticians would like to have a set of functions to compute the
median and mode of a list of numbers. The median is the number that
would appear at the midpoint of a list if it were sorted. The mode
is the number that appears most frequently in the list. Define
these functions in a module named stats.py. Also include a function
named mean, which computes the average of a set of numbers. Each
function expects a list of numbers as an argument and returns a
single number.
