Answer to Question #316833 in Python for MODE2

Question

Mode

given a list of integers,write a program to print the mode.

mode - the most common value in the list. if multiple elements with same frequency are present, print all values with same frequency in increasing order.

input

the input will be a single line of containing space-separated integers.

output

the third line of output should contain the mode.

see sample input/output for the output format

explanation 

for example, if the given list of integers are 

2 6 3 1 8 12 2 9 10 3 4

the average of all the numbers is 4.67.

after sorting the array,

1 2 2 3 3 4 6 8 9 10 12

as 2 and 3 are having the same frequency , the mode will be 2 3.

so the output should be

Mode: 2 3

sample input 1

2 6 3 1 8 12 2 9 10 3 4

sample output 1

Mode: 2 3

Answer 1

line = input()
L = [int(s) for s in line.split()]


L.sort()


mode = []
fr = 0
max_fr = 0
prev_x = None


for x in L:
    if prev_x is None:
        fr = 1
    elif x != prev_x:
        if fr > max_fr:
            max_fr = fr
            mode = [prev_x]
        elif fr == max_fr:
            mode.append(prev_x)
        fr = 1
    else:
        fr += 1
    prev_x = x


for m in mode:
    print(m, end=' ')
print()
