Hi Steve,
First up, a quick comment: There is a string module in the standard
library, and it has a function called join(). So it's generally a
good idea not to use 'string' as a variable name, as it can confuse
people :-)
Now, to your question: your string is 'abc'. It doesn't matter that
you're using a string to join itself; what you've written is identical
to:
>>> 'abc'.join('abc')
'aabcbabcc'
Let's change the call slightly to make things more clear:
>>> 'abc'.join('ABC')
'AabcBabcC'
Does that make the pattern more clear?
