do mean in python code example

Example 1: calculate mode in python

# Calculating the mode when the list of numbers may have multiple modes
from collections import Counter

def calculate_mode(n):
    c = Counter(n)
    num_freq = c.most_common()
    max_count = num_freq[0][1]
    
    modes = []
    for num in num_freq:
        if num[1] == max_count:
            modes.append(num[0])
    return modes

# Finding the Mode

def calculate_mode(n):
    c = Counter(n)
    mode = c.most_common(1)
    return mode[0][0]

Example 2: calculate mean on python

def calculate_mean(n):
    s = sum(n)
    N = len(n)
    
    mean = s / N
    
    return mean
