Truly?  I ran that line and found it works perfectly.

What version of python are you using (I used 2.5.1).
What OS?  (That should not matter, however you should tell us anyway.)
Are you sure your codecs is the Python module imported normally.  (You 
may have to show us all your code.)

With no code and a careful look at your error message, here's my guess:

That error message is what you get when you call an instance's method 
with the wrong number of arguments.  (And in that case the extra 
argument it's referring to is the instance itself begin passed in as the 
first (self) parameter.)

I believe your codecs value is no longer the imported module, but rather 
some instance object you've assigned into it:
  codecs = ...something overwriting the module object ...
