itertools, groupby solution in Creative category for Long Repeat by DenysChy
from itertools import groupby

return 0
else:
return max([len(list(group)) for key, group in groupby(line, lambda x: x)])

#These "asserts" using only for self-checking and not necessary for auto-testing
assert long_repeat('sdsffffse') == 4, "First"
assert long_repeat('ddvvrwwwrggg') == 3, "Second"
assert long_repeat('abababaab') == 2, "Third"
assert long_repeat('') == 0, "Empty"
print('"Run" is good. How is "Check"?')
