Two solutions but not two results [solved]

Question

I realise this is a very theoretical problem. But in my code
https://code.sololearn.com/cO5N7UzCfAdu/#py
lines 7/8 and 10/11 contain independent solutions to the given problem. When run individually on their own they work and return the reversed string.
When I have them both in the same code, I expected to get the same output (reversed string) twice. But it only appears once.
Does anybody know why that is ?
Thanks!

Answer 1

Matthias The iterator returned by reversed is exhausted by the join method resulting in a StopIteration state and it can't be reset to its original state.
So it can't be used more than once.
Solution:
c = list(reversed(a.split()))

Answer 2

Matthias Because c is an object. Just print c and see what you get.

You need to change

for i in d:

Here is correct solution:
------------------

a = "This is a test"

c = reversed(a.split())

d = ' '.join(c)
print(d)

for i in d:
print(i, end = "")

Answer 3

Thanks Kevin! That explains it.

And also thanks to the other replies. Much appreciated!

Answer 4

Thanks but what I meant was the following.

This code works on its own:
a="This is a test"
c=reversed(a.split())
for i in c:
print(i, end=" ")

And this code also works on its own:
a="This is a test"
c=reversed(a.split())
d=' '.join(c)
print(d)

When combined they should return the same result twice. But I get it only once.
