Typo in Encode as String

[ArtichokeSap]

Hey @rsokl , in the Encode As String Problem in Module 2, there's a small typo, where it says:

We use the str.join function along with a generator comprehensions in a couple places in our solution. Recall that

"<hi>".join(x for x in some_iterable_of_strings)

is equivalent to the long-form code:

out = ""
for x in some_iterable_of_strings:
    out += "<hi>" + x

But the former makes
item1<hi>item2<hi>item3
while the latter makes
<hi>item1<hi>item2<hi>item3

I would just make a pull request, but I'm not a natually pythonic coder to make equivalent, but still elegant code using a for loop; so I don't even know what to change it to. For example, this does produce the output, but is ugly coding:

out = ""
num_elements = len(some_iterable_of_strings)
count = 0
for x in iterable_of_strings:
    count += 1
    if count < num_elements:
        out += x + '<hi>'
    else:
        out += x

Ultimately that doesn't satisfy me with the intention of "is equivalent to the long-form code".

Thanks for catching this! I will try to cook up a good fix for this discrepancy. I appreciate you taking the time to post this.

@ArtichokeSap I fixed this here: 96add6a
