You can still simplify this even more, for example:

if (python === "python") {
  rank += 1;
//} else if (python !== "python") {
//  rank = rank;
}

The lines shown commented out can be omitted entirely since "rank = rank" doesn't change anything.

But you mentioned keeping track of points lost, so you might want to do something like this:

if (python === "python") {
  rank += 1;
} else {      // another "if" not needed
  lost += 1;  // keep count of missed questions
}

And when posting code to the forum, use Markdown formatting to preserve the appearance and optionally add syntax coloring (as shown here).

I didn't use it while composing this answer, but I do use MDN frequently and have had no problems with it.
