Is this error not clear enough? The function expects 3 arguments, you have 
given it 4. You need to give one fewer.

The only tricky thing to remember is that when you have a method, one argument 
is the automatically provided "self" argument:

function(a, b, c, d)  # This is FOUR arguments.

instance.method(a, b, c)  # So is this, because there is also a "self" arg.
