How do I get a variable to work when I'm printing text either side of it? You can import it from a similarly named StringIO module, or cStringIO for a faster implementation.

Preventing a line break in Python 2 requires that you append a trailing comma to the expression: However, thats not ideal because it also adds an unwanted space, which would translate to end=' ' instead of end='' in Python 3.
