Lesson 3.3.3 python big hacks

#PYTHON HACK 1

#Define a list of integers
integers = [2, 8, 14, 21, 33]

#Function to calculate arithmetic mean
def calculate_mean(numbers):
    return sum(numbers) / len(numbers)

#Function to calculate median
def calculate_median(numbers):
    sorted_numbers = sorted(numbers)
    mid_index = len(sorted_numbers) // 2
    
    #use the middle element
    return sorted_numbers[mid_index]

#Calculate mean and median
mean = calculate_mean(integers)
median = calculate_median(integers)

#Print the results
print("Arithmetic Mean:", mean)
print("Median:", median)


Arithmetic Mean: 15.6
Median: 14
