Using .__slots__, you can create a class that works as a namespace for read-only constants: Python >>> class ConstantsNamespace: ... __slots__ = () ... PI = 3.141592653589793 ... EULER_NUMBER = 2.718281828459045 ... >>> constants = ConstantsNamespace() >>> constants.PI ...
class Circle: def __init__(self, radius): self.radius = radius # Class implementation... class Square: def __init__(self, side): self.side = side # Class implementation... Once you have a class for each shape, you can write a function that takes the name of the shape as a str...

Using ABC as a base class has essentially the same effect as specifying metaclass=abc.ABCMeta, but is simpler to type and easier to read. (Contributed by Bruno Dupuis in bpo-16049.) aifc The getparams() method now returns a namedtuple rather than a plain tuple. (Contributed by Claudiu ...

classPerson:definit(self,name,age):self.name=name self.age=age If you want to create a second constructor that only takes in a name and sets the age to 0 by default, you can do this: classPerson:definit(self,name,age):self.name=name ...
usually be on separate lines, e.g.: Yes: import os import sys No: import sys, os it's okay to say this though: from subprocess import Popen, PIPE - Imports are always put at the top of the file, just after any module comments and docstrings, and before module globals and constants...
