Experimenting with the Counter Class solution in Clear category for The Most Wanted Letter by zero_loss
def checkio(text):
from collections import Counter

common = Counter(text).most_common()
common = [x for (x,y) in common if y == common[0][1]]
common.sort()
return common[0]
#These "asserts" using only for self-checking and not necessary for auto-testing
if __name__ == '__main__':
assert checkio("Hello World!") == "l", "Hello test"
assert checkio("How do you do?") == "o", "O is most wanted"

assert checkio("Oops!") == "o", "Don't forget about lower case."
assert checkio("AAaooo!!!!") == "a", "Only letters."
assert checkio("abe") == "a", "The First."
print("Start the long test")
assert checkio("a" * 9000 + "b" * 1000) == "a", "Long."
print("The local tests are done.")
