I wanted to have 2 insted 3 lines. Beside PyCharm pep8 checker does not complain about it. Another words "why not?"

Readability counts. <pre class='brush: python'>def long_repeat(string, gb=__import__('itertools').groupby): return max([len(list(g)) for _, g in gb(string)]+[0]) </pre> one-liner ? Think of the user's manual for this function: " ... it also has the second parameter, but NEVER TOUCH IT!"
