Question

I am using Python 3.3. Pygame uses tuples for colors. I need to halve each of the values in a tuple to make a darker color, but many times per second. I could use this function I wrote:

def halfTuple(oldTuple):
    newList = []
    for item in oldTuple:
        newList.append(item * .5)
    return tuple(newList)

but it might be slow. Is there a faster way to do this?

Answer 1

It’s likely that creating a new tuple from scratch instead of converting from an array will help:

def halfTuple(oldTuple):
    return tuple(x * 0.5 for x in oldTuple)
