It's not a string it's a cStringIO.StringIO, even though his variable
name is confusing.

nayden: 'str' is a built-in variable that is the string type. Try this
for different values of x:
type(x) is str
str(x)
When you override it, it may be confusing down the line.

I'd suggest installing pychecker, which will help you catch errors
like this:
