There are many times when we need to write lines of code that are so long that they're very hard to read. Many people like to limit the length of a line of code to 80 characters or fewer. It's a well-known principle of graphic design that a narrower line is easier to read; opinions vary, but 65 characters is often cited as ideal. See http://webtypography.net/2.1.2.
While shorter lines are easier on the eyes, our code can refuse to cooperate with this principle. Long statements are a common problem. How can we break long Python statements into more manageable pieces?
