The Zen of Python, Explained
Posted by Al Sweigart in misc
The Zen of Python by Tim Peters are 20 guidelines for the design of the Python language. Your Python code doesn’t necessarily have to follow these guidelines, but they’re good to keep in mind. The Zen of Python is an Easter egg, or hidden joke, that appears if you run import this.
Python's Fake Increment and Decrement Operators
Posted by Al Sweigart in misc
In Python, you can increase the value of a variable by 1 or reduce it by 1 using the augmented assignment operators. The code spam += 1 and spam -= 1 increments and decrements the numeric values in spam by 1, respectively.
Other languages such as C++ and Java have the ++ and -- operators for incrementing and decrementing variables. (The name of C++ itself reflects this; the name is a tongue-in-cheek joke that indicates it's an enhanced form of the C language.) Code in C++ and Java could have ++spam or spam++. Python wisely doesn't include these operators; they are notoriously susceptible to subtle bugs.

Django is a web app framework for Python (similar to Rails for Ruby). It implements common web app features so you don't have to write that code. Dreamhost is a web host that offers cheap but reliable web servers. Their shared hosting plan is $11 a month, and provides more than enough disk space and bandwidth for personal sites.
