The ** operator will, internally, use an iterative function (same semantics as built-in pow () ( Python docs ), which likely means it just calls that function anyway). Therefore, if you know the power and can hardcode it, using 2*2*2 would likely be a little faster than 2**3. This has a little to do with the function, but I believe the main ...Feb 4, 2015 · 7.
