Python Counting - finding the most common occurence

Python tip:

You can use Counter from the collections module to find the most common element in a:

• string - character with the most occurrences
• dict - key with highest value
• list - element with the most occurrences

most_common(n) -> returns n most common element

from collections import Counter

counter = Counter("TestDriven.io tutorials")
print(counter.most_common(1))  # character with the most occurrences
# => [('t', 3)]

counter = Counter({"red": 2, "green": 10, "blue": 7})
print(counter.most_common(1))  # key with the highest value
# => [('green', 10)]

counter = Counter([0, 2, 1, 1, 4, 10, 33, 21, 12, 10, 1])
print(counter.most_common(1))  # element with the most occurrences
# => [(1, 3)]
