Youll find out how they originated and whether you should follow them. If the implementation is easy to explain, it may be a good idea. In this tutorial, youll be exploring the Zen of Python, a collection of nineteen guiding principles for writing idiomatic Python. If the implementation is hard to explain, it's a bad idea.
There should be one- and preferably only one -obvious way to do it.Īlthough that way may not be obvious at first unless you're Dutch.Īlthough never is often better than *right* now. Some of the principles that influenced the design of Python are included as an Easter egg and can be read by using the command inside Python interpreter interactive mode: > import this The Zen of Python, by Tim Peters Beautiful is better than ugly. In the face of ambiguity, refuse the temptation to guess. You'll find out how they originated and whether you should follow them.

If you browse the PEPs you can read about the rationale for many language features at the time they were first proposed, and see some potential new features ( PEP465 is exciting for scientists!).Īnyways, PEP8 is a little different, it contains all the style recommendations for coding in Python, such as where to put whitespace and how to name things. PEP stands for Python Enhancement Proposals and it is where ideas for changing Python are formalized, to eventually become part of the langauge or die out.
