Efficiency Question

Question

Which of these, if they were to be called regularly, would be more efficient?

Pseudo code:

If num != 1:
num = 1

Or........

num = 1

My question i guess is it faster to confirm that the number is a 1 or faster to just assign it anyway and move past it?

Answer 1

If you'd decide to simply assign it and move on, it'd probably benefit you to note the repercussions ahead of time, depending on what you'd be doing, etc.

Answer 2

In first an extra check if made in if condition. So definitely assignment faster than check + assignment.

Answer 3

What the benefit of condition there..?
Anyways always num=1
