tef tef

When I was a younger, petulant mess of a programmer, I too waltzed into python and the explicit self. I'd done Java, JavaScript, and a handful of terrible languages not even worth mentioning. I didn't like it much, but I'd often used /this.foo/ instead of /foo/ in Java. I liked to be able to see what I was doing. I wasn't so keen on what seemed to be self sneaking into my method arguments. Now I've been using python for a bit, it's probably the best feature of python.

Let's take a step back and look why it's there and what it does for us: Python doesn't have methods: It has functions in classes. This means you can call a method explicitly on an object, ClassName.method(object, args). This also means you can pull the function out and assign it to other classes, ClassOne.foo = ClassTwo.foo. It also means that obj.foo() is actually two operations, method = obj.foo; method(). The choice of making methods out functions gives us unique ways to build classes, and also lets us take a method and pass it around as a

	$ cat foo.py
	def foo(x):
	return x
	$ cat bar.py
	from foo import foo

	def bar():

	from foo import foo
