Title: Update wording in tutorial

The sentence "Remember that `(float, float)` is a tuple of two floats" sounds like I missed a section on tuples,
when in fact it has not come yet. Change the wording to say "assume" since the reader is taking on good faith
at this point that the code snippet does represent a two-item tuple.
