def long_repeat(line):
    l = len(line)
    a = [1]
    for i in range(l-1):
        b = 1
        c = i+1        
        while c < l and line[i] == line[c]:
            b += 1
            c += 1             
        a.append(b)

Nice! I have a question about declaring a as [1], i'm new to coding so can you explain a bit further why?

It's needed for the case with one letter in the string. If l = len(line) =1 then l-1 would be 0, thus *_for_* cycle in line 4 wouldn't start and empty list a will drop in max function. max function can't work with empty lists so this will arise error: "ValueError: max() arg is an empty sequence" My code with a=[ ] also passed all authors checks, probably they missed 1 symbol check for this task.
