class too big for one file! How can I split it?

I strongly recommend you split your class into several smaller classes. 
However, if that really isn't possible, then you could use the execfile 
function. The example below executes each of the included files as though 
it were indented in the class definition even though it is a separate file.

You will get a performance hit on startup though as the included files will 
be compiled every time you run the program instead of being cached in the 
.pyc file.

OTLib.py:
---------------
XX = None

class Ot:
    def __init__(self, a = None, e = None):
        global XX
        XX = e    
    execfile("OTLib_Att.py")
    execfile("OTLib_Btt.py")
---------------

OTLib_Att.py
---------------
def Att(self):
    global XX
    print XX
---------------
OTLib_Btt.py
---------------
def Btt(self):
    global XX
    print XX
---------------

Also though, if I were you I'd drop the global and just make XX a class 
variable you can refer to as Ot.XX, or self.XX if not changing the value. 
If you do that then you can simply define the extra methods in another 
module and assign them into the class. This gets round the compilation hit 
that I described above.
