Hi Henry,

Thanks for the kind words. I’m trying to resume blogging as best I can but a one moth old eats up a lot of free time! Not to mention moving cities and a new house!

I have something that I’m hoping to get up soon, and hopefully in the future there will be less time between posts!

He seems to have resumed blogging again. Check out the post he made in January of this year. I’m happy he’s back

Just wondering why we have not seen you in a long time.
I personally have missed your amazing step-by-step tutorial.

We hope you’re fine and wish you the very best.
Good luck

This is great. I was having difficulties because of spaces in my indentation, but that has now been solved. It took me days to figure the indentation problem out as a beginner

Nice tutorial BTW ..

You said “handled so *wall*” instead of “handled so *well*”. Ted mentioned this, but he was talking about a few other errors two, so you probably didn’t notice the change.

Thanks for these tutorials. They are the best I have found so far.

Sorry for that last question. You have said in your article that the iterator protocol demands that once StopIteration is raised, it should continue to be raised.

Hi,
Thanks for the article. Am just discovering the joy of python programming.

I am confused about why “iterators…are only good for one pass over the data.”. Surely that depends on how we define the ‘next’ function. Suppose we define the ‘next’ function in Listing 2 like this( i reset the counter just before StopIteration is raised ):

def next(self):
if (self.current_item == len(self.data)):
# reset counter
self.current_item = 0
raise StopIteration
else:
byte_value = ord(self.data[self.current_item])
self.current_item += 1
return byte_value

we will be able to reuse the iterator. In the ‘generator’ object, I guess this happens automatically since the ‘counter’ is local to the generator object.

Thanks for this article.

I was missing some bits regarding the generators and now it is crystal clear.

I will recommend it
