If you have a list "l" and want a generator
Prahallad Achar writes:

If you have a list "l" and want a generator, you can use
( x for x in l)
or simpler "iter(l)" - which gives you an interator over "l".
An "iterator" is slightly more general than a generator
(every generator is also an iterator).

I get list object instead gen obj

How about reversed(list1) ?
ChrisA
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

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:
* Some code you would maybe expect to
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?
Thanks and Regards
