# Please create a Python code that will write the 3 most common words from the
# given list to standard output.
#
# Preferred output format is a list of (word, count) tuples, e.g.:
#
# $ python words.py
# [('apple', 5), ('banana', 4), ('orange', 3)]
#
# Ideally, the list should be sorted by word frequency.
#
# Feel free to utilize features that are available in Python 3.9.
