i think its ok solution in Clear category for Long Repeat by Alexey.K.
def long_repeat(line: str) -> int:
"""
length the longest substring that consists of the same char
"""
if line:
out = "".join(list(line[0])+[line[x] if line[x-1]==line[x] else ","+line[x] for x in range(1,len(line))])
else:
return 0
return max(len(s) for s in out.split(','))
if __name__ == '__main__':
#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"?')
