Answer to Question #179548 in Python for adhi chinna

Question

Mean, Median and Mode

Given a list of integers, write a program to print the mean, median and mode.

Mean - The average value of all the numbers.

Median - The mid point value in the sorted list.

Mode - The most common value in the list. If multiple elements with same frequency are present, print all the values with same frequency in increasing order.Input

The input will be a single line containing space-separated integers.Output

The first line of output should contain the mean, round off the value to 2 decimal places.

The second line of output should contain the median, round off the value to 2 decimal places.

The third line of output should contain the mode.

Mean should always be a float value.

Median should be a float value when there are even number of elements, otherwise should be an integer value.

Sample Input 1

2 4 5 6 7 8 2 4 5 2 3 8

Sample Output 1

Mean: 4.67

Median: 4.5

Mode: 2

Answer 1

def get_median(arg_list):
    arg_list.sort()
    size = len(arg_list)
    if size %2 == 1:
        return arg_list[size//2]
    else:
        return (arg_list[size//2] + arg_list[size//2 -1])/2
    
    
def get_mean(arg_list):
    sum_list = 0
    for i in arg_list:
        sum_list +=i
    return round(sum_list/len(arg_list), 2)




def get_mode(arg_list):
    mode_list = sorted(set(user_list), key=user_list.count,reverse=True)
    mode_max = user_list.count(mode_list[0])
    mode_res = []
    for i in mode_list:
        if user_list.count(i) < mode_max:
            break
        mode_res.append(i)
    return sorted(mode_res)


        
user_str = input('Enter a string of integers separated by a space: ')
user_list = [int(i) for i in user_str.split()]
print('Mean :', get_mean(user_list))
print('Median :', get_median(user_list))
# Displaying mode list values separated by a space
print('Mode :', *get_mode(user_list))
