TypeError: no arguments expected

[shawn a]

I havet these 2 files in the same dir. This is code im writing to learn pythong
mkoneurl.py:
#! /usr/bin/env python

import make_ou_class

run = make_ou_class.m akeoneurl()

=============== =============== ======
make_ou_class.p y:

class makeoneurl:
def __init__():
self.commandlin e()

def commandline():
com = raw_input(":")
#Parse out any params and aguements - reg expressions
#params[] array to hold paramters
params = 0
if com == "ou":
self.ou(params)
else:
print com + " unknown command."

def ou(params):
print "hello world"
self.commandlin e()

=============== =============== =============== ==
when i run the script like this: python mkoneurl.py
I get this error:

Traceback (innermost last):
File "mkoneurl.p y", line 5, in ?
run = make_ou_class.m akeoneurl()
TypeError: no arguments expected

Ive looked around for this exeption but nothing ive read has help in
this situation.
Any of your thoughts are greatly apprectiated. THANK!!

put "self" as the first argument in all instance methods of that class.
"self" is just a convention, referring to the object instance, not a
language feature as in other language like javascript. You can call it
"me" too if you prefer.

But please don't call it "me". The convention to call the first argument
"self" is so universal, calling it anything else is just going to make your
code more difficult for anybody else to read.

Add "self" as the first or only parameters to all methods.

Re-read the tutorial -- you're missing very crucial parts of it.

Let's get the terminology right: sloppy terminology leads to sloppy
thinking. The statement binds the name "run" to a newly-created
"make_one_u rl" instance. Remember, "run" isn't an object, it's a
reference to an object like all Python names.[color=blue]

Again you need to be a little careful here, since we now have class
methods and static methods to cloud the picture. So it would be more
accurate to say that "instance methods are all automatically called with
a reference to the instance as the first argument; it is conventional to
use the name 'self' to refer to the instance".[color=blue]
