If you don't want to have to put the factor30 in front of all your function
names you can do this:

from factor30 import *

Which will put all of your functions into the global namespace.

Then you can call factor() & factor0()  as you would expect to.

Thank you very much

Next dilemma is:


>>> v = [2, 35715, 17859, -318417088, 8932, 17860, 1000009, 5]
>>> v = transfac(v)
-1
2 35715 17859 -318417088 8932 17860

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
