Python: Get the frequency of the elements in a list

Sample Solution:-

Python Code:

import collections
my_list = [10,10,10,10,20,20,20,20,40,40,50,50,30]
print("Original List : ",my_list)
ctr = collections.Counter(my_list)
print("Frequency of the elements in the List : ",ctr)

Sample Output:

Original List :  [10, 10, 10, 10, 20, 20, 20, 20, 40, 40, 50, 50, 30]                                         
Frequency of the elements in the List :  Counter({10: 4, 20: 4, 40: 2, 50: 2, 30: 1})

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
