An Introduction to Compassionate Screen Scraping. Screen scraping is the art of programatically extracting data from websites.
If you think it's useful: it is. If you think it's difficult: it isn't. And if you think it's easy to really piss off administrators with ill-considered scripts, you're damn right. This is a tutorial on not just screen scraping, but socially responsible screen scraping. Its an amalgam of getting the data you want and the Golden Rule, and reading it is going to make the web a better place. Code Like a Pythonista: Idiomatic Python. In this interactive tutorial, we'll cover many essential Python idioms and techniques in depth, adding immediately useful tools to your belt.

A side remark about not supporting tail recursion elimination (TRE) immediately sparked several comments about what a pity it is that Python doesn't do this, including links to recent blog entries by others trying to "prove" that TRE can be added to Python easily. So let me defend my position (which is that I don't want TRE in the language). If you want a short answer, it's simply unpythonic. Here's the long answer: Documentation Index.

They will usually be assigned on Thursday and due the following Friday. Toward the end of the course, the assignments will be a little more challenging and 2 weeks will be allowed to complete them. Assignment 1, to be completed in section week of Feb. 1, but give it a try before then. Python - Notes.
You have seen how you can reuse code in your program by defining functions once.
What if you wanted to reuse a number of functions in other programs that you write? As you might have guessed, the answer is modules. There are various methods of writing modules, but the simplest way is to create a file with a .py extension that contains functions and variables. Another method is to write the modules in the native language in which the Python interpreter itself was written. Python Warmup-1 sleep_in. Structuring Your Project — pythonguide 0.0.1 documentation. By “structure” we mean the decisions you make concerning how your project best meets its objective.
We need to consider how to best leverage Python’s features to create clean, effective code. In practical terms, “structure” means making clean code whose logic and dependencies are clear as well as how the files and folders are organized in the filesystem. Is there a way to access hardware directly in Python. | Did you know that?
