The philosophy of Python (programming language) is summarized in a module called Zen of Python that is a collection of 19 software principles that inspires the design of Python programming language [1].

Zen of Python by Tim Peters [2] is written as an informational entry number 20 in Python Enhancement Proposal (PEP), and can be found on the official Python website. It is also included as an easter egg in Python interpreter, which would be displayed by entering a statement
import this

Principles will be printed as follow:

The Zen of Python, by Tim Peters

  • 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.
  • Error should never pass 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!
