I would change this block:
“The first line contains a multiple assignment: the variables a and b simultaneously get the new values 0 and 1. On the last line this is used again, demonstrating that the expressions on the right-hand side are all evaluated first before any of the assignments take place. The right-hand side expressions are evaluated from the left to the right.”
To this:
"The first line contains a multiple assignment - which we haven’t seen before:
The variables a and b simultaneously get the new values 0 and 1 respectively, it’s equivalent to doing a=0 && b=1.
On the last line this is used again, (a,b) = (b, b+a),
Demonstrating that the expressions on the right-hand side are all evaluated first before any of the assignments (change of value of a and b on the left side) take place. The right-hand side expressions are evaluated from the left to the right.
