Python: Find the item with maximum frequency in a given list

Python Collections: Exercise-20 with Solution

Write a Python program to find the item with maximum frequency in a given list.

Sample Solution:

Python Code:

from collections import defaultdict
def max_occurrences(nums):
    dict = defaultdict(int)
    for i in nums:
        dict[i] += 1
    result = max(dict.items(), key=lambda x: x[1]) 
    return result
nums = [2,3,8,4,7,9,8,2,6,5,1,6,1,2,3,2,4,6,9,1,2]
print ("Original list:")
print(nums)
print("\nItem with maximum frequency of the said list:")
print(max_occurrences(nums))

Sample Output:

Original list:
[2, 3, 8, 4, 7, 9, 8, 2, 6, 5, 1, 6, 1, 2, 3, 2, 4, 6, 9, 1, 2]

Item with maximum frequency of the said list:
(2, 5)

Python: Tips of the Day

Use Reversed() In for Loops:

>>> tasks = ['laundry', 'picking up kids', 'gardening', 'cooking']
>>> for task in reversed(tasks):
...     print(task)
... 
cooking
gardening
picking up kids
