Don't forget the ball you can have with the power of ordinary Python
strings, string methods, and string interpolation!
originalString = "spam:%(first)s ham:%(second)s"
print originalString % { "first" : "foo" , "second" : "" }
prints
spam:foo ham:
with far fewer surprises and false steps. (Note: Py3K supports this
same feature, but with different interpolation syntax, which I have
not learned yet.)
Book recommendation: Text Processing in Python, by David Mertz (free
online - http://gnosis.cx/TPiP/), in which David advises against
dragging out the RE heavy artillery until you've at least thought
about using ordinary string methods.
