I'm kind of partial to:
import collections
import typing
def get_longest(string: str) -> typing.Tuple[int, str]:
"""Get the longest run of a single consecutive character."""
dict_: typing.DefaultDict[str, int] = collections.defaultdict(int)
for left_ch, right_ch in zip(string, string[1:]):
if left_ch == right_ch:
dict_[left_ch] += 1
maximum = max((value, key) for key, value in dict_.items())
return maximum
