Special cases aren't special enough to break the rules. If you do so in a REPL, you’ll see this: > import this You can trigger the easter egg by importing the module this. The Zen of Python easter eggĪ little Easter egg that has been present in Python for a long time lists the Zen of Python. Python devs kept finding new and better ways to do this over the years but had to keep the old ways intact for compatibility. As an example, there are now three ways to format strings in Python: It’s not all rainbows and sunshine, however. In contrast, some other languages that don’t have such a defined way of doing things end up with a myriad of object methods like object.length(), object.size(), etcetera, all with slightly different names depending on the one who implemented it. After all, Python has the len() function that works on any object with a length, giving us only one clear way to get the length of an object. It is clearly applied to how we can get an object’s length in Python. To this day, Python developers, especially those working on the Python project itself, try to adhere to these principles.Īs an example of how these rules apply to the Python language, we can look at rule 13 (there should be one – and preferably only one – obvious way to do it).

How the Zen of Python is visible throughout PythonĪs mentioned, these rules are partly inspired by PEP-8, the Python style guide written by Guido van Rossum.
