Answer 1

HonFu
after yield the programm returns the value.
it is first the inner yield... it is evaluated first
and after the outer one.. which evaluated to None.
so... yes...

Answer 2

You have generator functions there.

Whenever you call them, you get a generator object, that follows the code of the function body, usually handing out values one by one (in this case only one).

* just unpacks any iterable, also generator objects, in one run, so that you can for example - as done here - print them out one by one.

You should read/repeat the tutorial lesson about generators.

Answer 3

very tricky
* makes the music
it makes the generator iterate.
without it only generator object is yielded/returned.

Answer 5

HonFu i mean yield (yield 5)
so the yield 5 gives a generator and now yield (generator) gives None but when in another case the generator is yielding 4 when yielding the value

Answer 6

Hm.

Is yield (yield 5) synonymous with this?

yield 5
yield

Answer 7

HonFu Oma Falk
in code 1
yield (yield 5) how it will be processed
if yield 5 in bracket is processed than the o/p will be a generator object stored somewhere so now as the yield 5 is giving generator object and which is followed by another yield function so now yield (generator) generator is the o/p of yield 5 than it is giving None

but in code 2
star() is yielding a generator object too
which in another function is followed by another yield (generator_object) o/p of star function but the o/p in both the case are different one is giving 4 and another is giving None while processing 2nd yield

Answer 8

sorry not 4 but giving generator objects location
