does python has a way to implement C#-like indexers? -

-

this question has answer here:

how implement in python c# indexers-like this[int i] {get set}? in other words, how write follow code in python?

public class foo{     ...     list<foo2> objfoo;     ...     public foo2 this[int i] {       get{ return objfoo[i]; }} }//end class foo  //in class or method... ofoo = new foo(); ... foo2 x = ofoo[3];

if want make class work python list (which similar arrays in other languages), can subclass list , give class custom methods , properties without overriding of list methods or properties unless need to.

trying mimic of you've posted:

class foo(list):     def __init__(self, *args):         self.extend(args)         self.x = "now"      def smack(self):         print("smackity!")  ofoo = foo(1, 2, 3, 4, 5, 6) print(ofoo[3])  # prints 4 print(ofoo.x)   # prints "now" ofoo.smack()    # prints "smackity!"

you can use normal list methods add or change indexed items way want.

also, here's more on lists, if helps.
