Yes.  I don't use range() everyday, and it's very rare that I use more
than one argument.  I do remember that there are additional (optional)
arguments to range which alter the sequence (start point and step),
but I certainly don't remember which is which.  If I needed to use it,
I would go look it up.  On the other hand, if I saw "range (10,
step=2)" written, it would be immediately obvious what was going on
without need to refer to the docs.
