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.

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.

I often get emails say little more than "Why doesn't my program work?" Often I can't answer them; either I don't have enough information about your problem or you're asking me about something I don't know anything about.

This post contains the lessons I've learned and my process for creating video tutorials, and I hope others who want to do the same find it useful. While this post is specific to Udemy and programming courses, the same lessons probably apply to all online courses.

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.
