It's simple: <a href="https://docs.python.org/3/library/itertools.html#itertools.groupby">groupby</a> without specifying the key parameter produces groups of the equal elements. `sum(1...` counts groups. All elements are equal if there are less than 2 groups.

I like this solution. But it should be in clever category.
