nope, learning Python is much better. It is a really good book that teaches you even what's going behind the scenes in python. Diveintopyhon is good if you have no patience, but you probably will miss a lot things that "learning python" explains, especially if you are new into scripting languages (I came from Java, and some php experience).

Take a week and a half of time, two hours a day, and read it. Meanwhile make sure you practice some in your own, and then start a small real project, so you can actually start imprinting what you learnt.
