how to find mean, median, and mode in python

Question

A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set of numbers. Define these functions, median and mode, in a module named stats.py. Also include a function named mean, which computes the average of a set of numbers. Each function should expect a list of numbers as an argument and return a single number. Each function should return 0 if the list is empty. Include a main function that tests the three statistical functions using the following list defined in main:

userList = [3, 1, 7, 1, 4, 10]

Answer 1

You can directly use formulae for calculating them 

But we can do it with predefined functions by importing statistics and scipy modules

#Program

import statistics as st
from scipy import stats
userList = [3, 1, 7, 1, 4, 10]
print("Mean:" ,st.mean(userList))
print("Median:" ,st.median(userList))
print("Mode:", stats.mode(userList))
