A defaultdict is a dictionary subclass that provides a default value for missing keys.
from collections import defaultdict
word_counts = defaultdict(int)
words = ['apple', 'banana', 'apple', 'cherry']
for word in words:
word_counts[word] += 1
print(word_counts) # Output: defaultdict(int, {'apple': 2, 'banana': 1, 'cherry': 1})
