So after reading one of my Python books (available free online here and here), you're no longer a complete beginner and would like to know where to go next. It can be hard to find intermediate-level material: stuff that isn't for total beginners or advanced computer scientists. The topics that you should google for are Python standard library, Python object oriented programming, Python idioms, and popular Python modules.

For a more concrete list of resources, here's my list of recommendations.

Continuing with Python

Practicing Your Code-Fu

Moving On to Other Languages

Python is versatile and you can keep going down that path if you choose, but don't feel that you're somehow "not ready" to tackle a new language. If you do want to move on, here's some resources for the next step.

JavaScript: All dynamic behavior that happens in the browser is from JavaScript code. If you want to learn to create web apps, getting a basic understanding of HTML and CSS is recommended. The jQuery module is also standard for doing any web app development. My favorite JavaScript books are: Eloquent JavaScript (free), JavaScript and JQuery: Interactive Front-End Web Development, and (once you have some JS experience) Crockford's JavaScript: The Good Parts is the key book to read to understand the language.

Ruby: Ruby is a scripting language and similar to Python. It's noteworthy for the Ruby on Rails web app framework. You can try it out online at tryruby.org, and Codecademy has tracks for both Ruby and Ruby on Rails. But since you already know how to code, I'd suggest the Learn Ruby in 20 Minutes page on the official Ruby site.

Java or C#: These languages are fairly similar to each other. Java is the more popular one and a mainstay of software engineering jobs. C# is (essentially) Microsoft's version of Java, meant to create Windows applications. I don't have any recommendations as far as C# books, but Java: A Beginner's Guide is a decent intro. There have been plenty of slight changes to the Java language over the years, so you don't want to get a book that's more than a decade old or so.
