Python: Find the most common element of a given list

Python Collections: Exercise-15 with Solution

Write a Python program to find the most common element in a given list.

Sample Solution:

Python Code:

# Import the Counter class from the collections module
from collections import Counter

# Create a list 'language' containing programming language names
language = ['PHP', 'PHP', 'Python', 'PHP', 'Python', 'JS', 'Python', 'Python', 'PHP', 'Python']

# Print a message to indicate the display of the original list
print("Original list:")

# Print the content of the 'language' list
print(language)

# Create a Counter object 'cnt' to count the occurrences of each language in the list
cnt = Counter(language)

# Print a message to indicate the display of the most common element in the list
print("\nMost common element of the said list:")

# Find and print the most common element (programming language) in the list
# Note: In this case, it returns the first most common element
print(cnt.most_common(1)[0][0]) 

Sample Output:

Original list:
['PHP', 'PHP', 'Python', 'PHP', 'Python', 'JS', 'Python', 'Python', 'PHP', 'Python']

Most common element of the said list:
Python
