thank you all so much for the elaborate explanations! It's really
simple and crystal clear now, the most difficult part was actually to
detect and overcome my own misconceptions. Once I did that, the rest
was really easy. Kind of a valuable learning for the future ;-)

Be careful about terminology here. a,b is a single tuple with two
values. But a and b are variables not tuples.
Tuples are collections of (one or more)
Now I got it, thanks :-)

I suggest you play with the statement a bit. Print out both values
each time through the loop.
The expression b, a+b produces a tuple. The left side a, b *unpacks*
that tuple into
Hi,

Your issue is that you interpret the assignment wrong. You seem to think
that it assigns b to a and THEN a+b to b, which is not the case. The
right side of the assignment creates a tuple, and the left side unpacks
it. It is the same as
(key-len(self.fibsseq)+1):
self.fibsseq.append(self.fibsseq[-1] + self.fibsseq[-2])
return self.fibsseq[key]
