Multiplying a tuple by a scalar

Question

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,          


        

Answer 1

Solution:

set1=(70, 70)
tuple(2*array(set1))

Explanation: arrays make direct scalar multiplication possible. Hence the tuple called set1 here is converted to an array. I assume you wish to keep using the tuple, hence we convert the array back to a tuple.

This solution is to avoid the explicit and verbose for loop. I do not know whether it is faster or whether the exact same thing happens in both cases.
