how to calculate mean in python

import statistics

a = [1,2,3,4,5]

mean = statistics.mean(a) 
#Similar for other values such as variance, standard deviation

calculate mean on python

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

get mean using python

# --------------------- MEAN ---------------------

# Dataset for questions -
dataset = [2, 1, 1, 4, 5, 8, 12, 4, 3, 8, 21, 1, 18, 5]

# Finding sum of dataset
sumOfDataset = sum(dataset)

# Finding length of dataset
lenOfDataset = len(dataset)

# Calculating the mean by dividing the sum of dataset with the length of dataset
mean = sumOfDataset / lenOfDataset

# Printing the mean of dataset
print(mean)

python: mean average

def mean(numbers):
    numbers.sort()
    q = len(numbers) // 2
    if len(numbers) % 2 !=0:
        return numbers[q]
    elif len(V) % 2 == 0:
        return (numbers[q - 1] + numbers[q]) / 2
