Grid mesh Automation

I have a script for grid mesh Automation.

We need x value, y value, and face for doing the grid mesh.

As for face, I am creating a group for faces and I am using GetEntitesFromGroup command to get a list of faces and I am looping through each face in the list for doing the grid mesh. I have fixed X = 1 and Y = 2 in the script so all faces will get meshed with same parameters.

But the problem with the script is that the same X=1 and Y=2 cannot be used for all face groups.

Is there a way I can prompt the user to input x and y parameters so that I can use those values in script?
