Input/output arrays (1)

What if we really want to send a as argument and let F77 modify it?
    def ext_gridloop1(self, f):
        lx = size(self.xcoor);  ly = size(self.ycoor)
        a = zeros((lx,ly))
        ext_gridloop.gridloop1(a, self.xcoor, self.ycoor, f)
        return a
This is not Pythonic code, but it can be realized
1. the array must have Fortran storage
2. the array argument must be intent(inout)
(in general not recommended)
