Answer to Question #349735 in Python for Mani krishna

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 second 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-seperated 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 medium,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.

See sample Input?Output for the output format.

INPUT

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

Sample Output 1

Mean: 4.67

Median: 4.5

Mode: 2

Sample Input 2

2 6 3 1 8 12 2 9 10 3 4

Sample Output 2

Mean: 5.45

Median: 4

Mode: 2 3

Answer 1

The answer to your question.

number_str=input("Enter whole numbers separated by spaces: \n")
num=[]
for s in number_str.split():
    num.append(int(s))
num.sort()
print(num)
print("Mean: "+str(round(sum(num)/len(num),2)))
index = len(num)//2
if len(num)%2:
    median=num[index]
else:
    median=sum(num[index-1:index+1])/2
print("Median: "+str(median))
nx=num[0]
count=[]
f=0
for n in num:
    if n==nx:
        f=f+1
    else:
        count.append((nx,f))
        f=1
        nx=n
count.append((nx,f))
mode=[]
nx=0
for n in count:
    if n[1]>nx:
        nx=n[1]
for n in count:
    if n[1]==nx:
        mode.append(str(n[0]))
print("Mode: "+" ".join(mode))
