for removing a class in vim, get the plugin called:
pythonobj and in normal mode do:
dac

[heshers]

if you're using python3 and getting:
TypeError: iter() returned non-iterator of type 'Reverse'
change the following:

def next(self):

to:

def __next__(self):

Akash Sarda Iterators return an element one by one, and so do generators. However a generator is a statement that generates an iterator for a single use in one line. eg. 
var = [int for int in intList if int == value2]

You could also use string slicing to get the reversed string:

"teststring"[::-1] would result in a reversed string.

on the second iteration i got the error: SyntaxError: 'yield' outside function

[JabbaTiure]

I got:
"Traceback (most recent call last):
  File Projects/reverse.py", line 46, in <module>
    Main()
  File Projects/reverse.py", line 42, in Main
    for char in rev:
TypeError: iter() returned non-iterator of type 'Reverse', " in two instances where I used my own typed copy of your code as well as the original code you've uploaded to the bin using Python 3.4.x on Mac OS X. Addendum: And that is after enclosing 'char' within parenthesis to update the code to 3.4.x standards.

Sometime at the 5th or 6th minute the video and the sound get synchronized :(

So generators give the element one by one right? so Range is a generator?
