How about this
List1=[ 1,2,3,4]
Rever_gen = ( x*x for x in list1, reversed = True)
Rever_gen gets generator object and iterating it now gets reverse order..
Am I correct here? Suggest me

A generator generates a sequence of values.
The notion "reverse generator" suggests that you have a sequence
of values and want to produce it in reverse order.
This is not always possible.
Consider:
def natural():
i = 0
while True
Chris,
I don't wish to continue belaboring this topic but will answer you and then

Grant,
I can see why you may be wondering. You see the nan concept as having a
specific spelling using all lowercase and to an extent you are right.
As I pointed out. In the context of a string to convert to a float, any
upper/lower-case spelling of NaN is accepted.
But, to answer you anyway, I

That's curious. I've never seen "Nan" before. What version of Python
are you using?

Other people have replied well enough with better ways to do this but I am
stuck on WHY this was seen as a way to do this at all.
The code was:

try:
r = float(inp)
except ValueError:

Welcome to the Python forum!
That sounds like an interesting problem. Can you describe it more
precisely? What should a “reverse generator” actually do (and not do)?
Ideally, give an example:

How to implement reverse generator
It is only passing data in reverse or how it is
Yeild always returns next value and is question valid?

You can only decode FROM the same encoding you've encoded TO. Any decoding
must know the input it receives follows the rules of its encoding scheme.
latin1 is not utf8.
However, in your case, you aren't seeing problem with the decoding. That
step is never reached. It is failing to encode the stri
