Zen of Python

The Zen of Python are principles to follow for the programming language. It is included in PEP20 from 2004.

  • Beautiful is better than ugly.
  • Explicit is better than implicit.
  • Simple is better than complex.
  • Complex is better than complicated.
  • Flat is better than nested.
  • Sparse is better than dense.
  • Readability counts.
  • Special cases aren't special enough to break the rules.
  • Although practicality beats purity.
  • Errors should never pass silently.
  • Unless explicitly silenced.
  • In the face of ambiguity, refuse the temptation to guess.
  • There should be one-- and preferably only one --obvious way to do it.
  • Although that way may not be obvious at first unless you're Dutch.
  • Now is better than never.
  • Although never is often better than right now.
  • If the implementation is hard to explain, it's a bad idea.
  • If the implementation is easy to explain, it may be a good idea.
  • Namespaces are one honking great idea -- let's do more of those!


Python has conventions of how to indent, how to name variables etc. Those are summarized in PEP8. It is best to learn these conventions while programming, since your IDE has support for these formatting patterns and will probabely underline variables that do not confirm conventions. It is also best practice to use a linter, e.g. flake8 to ensure code formatting follows the standards.
