Sir, why are writing only yield a and not both a and b in Fibonacci function

[shreytalreja]

>>> def remote_control():
yield "CNN"
yield "ABC"
>>> rem = remote_control()
>>> next(rem)
'CNN'
>>> next(rem)
'ABC'
>>> next(reversed(rem))
Traceback (most recent call last):
File "<pyshell#25>", line 1, in <module>
next(reversed(rem))
TypeError: 'generator' object is not reversible
