2 gotos? While: If X Stuff Goto while. //Outside of while statement

  That actually shows two gotos (as you've written it) because the if is itself a goto, under the hood. The way to get it down to one is this pseudo-code: jump test loop: stuff test: test X jump if (not-equal/greater-than/less-than/etc) loop other stuff It still uses two jump or branch instructions, but the loop body only uses one. It falls through if the test fails. In the case of a do/while it's the same except you remove the initial jump.

    True, but The parents comment >since a while is just an if with two gotos isn't it? The if has to include at least one branch instruction so you already have 2 branches to play around with. Plus python doesn't have a goto so my code is pseudo code so I don't think that you can declare it is a goto under the hood.

    I would call an unconditional jump inherently different from a conditional one, i.e. both if and goto are primitives. Of course on some machines everything can be predicated and the line between an if and a goto is blurred. Then there are indirect jumps...
