Python beginners example: mean

#!/usr/bin/python
# -*- coding: utf-8 -*-

# f(x) = s(x) / l(x) ______(e1)
# Functions below same principle as (e1)
#
# Here,
# Mean value can be float
# 'er is need to declare float values

# Function to get mean of given args
def mean_(*args):
    sum_ = 0.0
    length_ = 0.0

    for arg in args:
        sum_ += arg
        length_ += 1.0

    return sum_ / length_

# Function to get mean of array
def mean_ar(ar):
    return float(sum(ar))/float(len(ar))

# Another feature can be start index
# and end index of array

# Test
# First function
if mean_(12, 445, 76, 23, 7, 9, 17, 19, 100) == 78.66666666666667:
    print("First Function Works!")

# Second function
if mean_ar([12, 445, 76, 23, 7, 9, 17, 19, 10]) == 68.66666666666667:
    print("Second Function Works!")
