Annoying tuple syntax: partial solution

Victor Ng writes about Python's tuple syntax for length one tuples.

Not that I use a lot of explicit length one tuples, but here's something you can do instead. Redefine the tuple function to accept non-sequences. If so, just put them in a length one tuple.

def tuple(x):
    try:
        return original.tuple(x)
    except TypeError:
        return original.tuple([x])
Then you can express an explicit length one tuple as tuple(x)
