I was wondering, is sf.Keyboard.is_key_pressed() expensive?
My tests lag considerably when there are 70+ controllable objects at a time (about 300 calls).
The profiler showed that 90% of the time was spent in the is_key_pressed() function so either I am doing something wrong or the function is expensive (after many calls that is).

One question: Why do you have 70 objects checking for keypresses? What kind of game do you control 70 objects at a time?
If you really need to have this many objects controllable at once, you could optimize by saving the result of is_key_pressed each frame and just checking the variable.

I can't understand why, in one cycle, you'd want to call isKeyPressed 300 times as it's highly unlikely that the keyboard has that many keys.
