[Tutor] How to convert the fortran logic to python definition

[SATYABRATA DATTA]

delta=18.*a*b*c*d-4.*(b**3)*d+b**2*c**2-4.*a*c**3-27.*a**2*d**2
         print *, delta, a, b, c, d,d1
         if(delta.gt.0.)then
         x=2.*b**3-9.*a*b*c+27.*a**2*d
         y=3.*sqrt(3.)*a*sqrt(delta)
         if((x.lt.0.and.y.lt.0).or.(x.lt.0.and.y.gt.0))then
         nii=2
         else
         nii=0
         endif
How to convert this fortran logic to python where delta(a,b,c,d)
should return x(a,b,c,d) and y(a,b,c,d) for the next job when
satisfied the conditions
