And another good reference for you to know about is the built-in help
system that comes with Python. For example, to learn a bit about why
Eric's code works the way it does:
>>> help("".join)
Help on built-in function join:
join(...)
S.join(sequence) -> string
Return a string which is the concatenation of the strings in the
sequence. The separator between elements is S.
In Eric's example, the variable 'a' was a type of Python sequence,
specifically, a list.
You could also achieve the same result of concatenating a list of
strings by looping over the list items like so:
b = ''
for fruit in a:
b += fruit
print b
