python - Multiplying a tuple by a scalar

I have the following code:

print(img.size)
print(10 * img.size)

This will print:

(70, 70)
(70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70, 70)

I'd like it to print:

(700, 700)

Is there any way to do this without having to write:

print(10 * img.size[0], 10 * img.size[1])

PS: img.size is a PIL image. I don't know if that matters anything in this case.

Might be a nicer way, but this should work

tuple([10*x for x in img.size])
