Kermit have you actually bothered going through any tutorials? You just seem
to be asking every time you get an error, I know the list is here for people
to ask questions but you really should try and work some things out for
yourself.

Traceback (most recent call last):
  File "<pyshell#8>", line 1, in -toplevel-
    v = transfac(v)
  File "c:\math\factoring\factor30.py", line 46, in transfac
    a,b,c,d,m,n = a,b.c+a*t,d-b*t,m+t,n
AttributeError: 'int' object has no attribute 'c'

Your problem here is that you have b.c instead of what I presume should be a
comma. b.c means that it's trying to find the method c of the integer b
which doesn't exist.
