Given a 2D list, write a Python program to find the most common element in each column of the 2D list.
Input : [[1, 1, 3], [2, 3, 3], [3, 2, 2], [2, 1, 3]] Output : [2, 1, 3] Input : [['y', 'y'], ['y', 'x'], ['x', 'x']] Output : ['y', 'x']
Method #1 : Using most_common() from collections module
most_common() return a list of the n most common elements and their counts from the most common to the least. Thus, we can easily find the most common elements in each column using list comprehension.
[2, 1, 3]
Method #3 : Using mode() from statistics module
[2, 1, 3]
