One common mistake newbies make in Python is calling the sorted method and expecting it to sort in place:
>>> x = [3, 2, 1] >>> sorted(x) [1, 2, 3] < sorted returned a new list >>> x [3, 2, 1] < x stayed the same >>> There are a few functions in the Python lib that have "InPlace" added to their names to avoid confusion, so it's not a new convention and it seems like a good way to go.
