Can I add custom methods/attributes to built-in Python types?
- by sfjedi
For example—say I want to add a helloWorld() method to Python's dict type. Can I do this?
JavaScript has a prototype object that behaves this way. Maybe it's bad design and I should subclass the dict object, but then it only works on the subclasses and I want it to work on any and all future dictionaries.
Here's how it would go down in JavaScript:
String.prototype.hello = function() {
alert("Hello, " + this + "!");
}
"Jed".hello() //alerts "Hello, Jed!"
