On the IBM developerWorks site there's a recent article looking to help PHP developers bridge the gap to Python by teaching some of the beginning steps in this other, different sort of language.
This article gives you a bit of exposure to Python. It assumes that you have no knowledge of that programming language, so some of what you read here might seem a bit basic. It focuses on comparing and contrasting Python with PHP - not because one language is better than the other but because of a simple truth: It's often easier to learn new things by referring back to something you already know.
They start off by introducing the language and talking about the differences between them including the differing syntax, Python's concept of mutability/immutability and the non-positional argument handling. From there, it's all about the basics - making a sample script, using loops, working with strings, conditionals, lists and dictionaries. A full sample script shows you how to pull it all together to pull in a list of files and outputs basic information about them.
