it's not perfectly clear to me what you mean with 'doesnt work'.

The two if parts

> if re.findall(pat1,something) and re.findall(pat2,something):
>                do something

and

> if re.findall(pat1,something) :
>                if re.findall(pat2,something):
>                            do something

look equivalent to me.  Could you please reveal your
value for text-string 'something'?  Further I suggest
to replace the 'do something'-parts with 'print 42'.
