Special cases aren't special enough to break the rules. The rules are written into the PEP 20 and can be found here: but on this post you will find them and examples of how to apply them.Įvery Python interpreter has an easy way to pull the zen of Python, just typing import this > import this There are only 19 rules to build code in Python and to unify the criteria on which decisions should be taken in case of doubts. 3.1 Python PEP 8 – How to style correctly your Python code.1.19 Namespaces are one honking great idea - let’s do more of those!.1.18 If the implementation is easy to explain, it may be a good idea.1.17 If the implementation is hard to explain, it’s a bad idea.1.16 Although never is often better than right now.1.14 Although that way may not be obvious at first unless you’re Dutch.1.13 There should be one– and preferably only one –obvious way to do it.1.12 In the face of ambiguity, refuse the temptation to guess.1.8 Special cases aren’t special enough to break the rules.There are in-jokes about the Parrot virtual machine and the "non-existent" Python Secret Underground (possibly a throw-back to "TINC" on USENET). Uncle Barry's official title is "FLUFL" (Friendly Language Uncle For Life). The new title given to him would be pronounced "BDEVIL" (Benevolent Dictator Emeritus Vacationing Indefinitely from the Language) and Guido's successor will be Barry Warsaw, or as he is affectionately known, Uncle Barry. The PEP states that Guido van Rossum is stepping down. The PEP 401 is an April Fools' Joke - The PEP's number is 401, i.e.The original code is here with the xkcd comic referenced, and maybe that's why this is also in the antigravity module.Though, it is not explicitly preferred while writing code, it adds flavour to working with scientific formulas Support for unicode character set for naming identifiers was added in Python3.The message has a hidden example in itself In many languages there are two ways to do the same thing -no and no.It's a substitution cipher called ROT13.Guido van Rossum is a big fan of Monty Python's Flying Circus.This is to instantly close down any conversation about introducing curly braces to Python.It opens this xkcd comic which demonstrates how easy it is to do stuff with modules.Not an easter egg, a joke in the interpreter.Maybe just to show that there always should be a new line at the end of a file!.Each and every line is the philosophy of Python's design and is a supreme holy guide.Easiest hello world program in a language without calling any function.Interestingly, hash(float('-inf')) yields -10^5 x pi in python3, whereeas -271828 i.e - 10^5 x e in python2. On a closer look, the hash of infinity is 10^5 x pi. > infinity = float ( 'infinity' ) > hash (infinity ) 314159 > hash ( float ( '-inf' ) ) - 314159Ī hash is a fixed sized integer that identifies a particular value. This would probably be the only module to go against the spirit of what it says itself. It's not beautiful but ugly, not explicit but implicit.
