Python Coding challenge - Day 345| What is the output of the following Python Code?

 

Code Breakdown:

from collections import Counter  

data = "aabbccabc"  

counter = Counter(data)  

print(counter.most_common(2))

1. from collections import Counter:

This imports the Counter class from Python's collections module.

Counter is a dictionary subclass designed for counting hashable objects, like strings, numbers, or other immutable types.

2. data = "aabbccabc":

A string data is defined with the value "aabbccabc".

It contains characters a, b, c, each repeated multiple times.

3. counter = Counter(data):

The Counter is created for the string data.

Counter(data) counts the occurrences of each character in the string:

a appears 3 times.

b appears 3 times.

c appears 3 times.

The Counter object will look like this:

{'a': 3, 'b': 3, 'c': 3}

4. print(counter.most_common(2)):

The method .most_common(n) returns a list of the n most common elements as tuples (element, count).

counter.most_common(2) retrieves the two most frequent characters along with their counts: Since a, b, and c all have the same count (3), the order in the result depends on their appearance in the original string.

The output will be:

[('a', 3), ('b', 3)]
