Python Code About Validating User Input

I have read alot about validating the user input at different websites, but I still wasn't able to find a method in python for generating the condition at "the end of the while statement"... Like in Visual Basic for example:

Do
    [ statements ]
    [ Continue Do ]
    [ statements ]
    [ Exit Do ]
    [ statements ]
Loop { While | Until } condition

So here is my code at the momen. I'm not sure, if everything is perfect. I am just a beginner ... Maybe somebody has more knowledge and can provide me with a simple way to get to the solution...

import Rhino as rhinoRef
import Rhino.Geometry
import rhinoscriptsyntax as rs
import math
import scriptcontext


def abcde():

    # Parameters 
    # standard values for parameters
    bx = 0.0 # base point coordinates
    by = 0.0
    bz = 0.0
    lCube = 10.0    # side length of cube
    rCyl = 1.0        # radius of cylinder
    hCyl = 20.0    # height of cylinder
    rSph = 6.0        # radius of sphere
    thSl = 0.3        # thickness of slot
    hSl  = 1.3        # height of slot
    
    # ask the user to pick a base point 
    BasePoint = rs.GetPoint("Pick base point")
    # ask the user to enter the side length for the cube
    lCube = rs.GetReal("please, enter the side length for the cube C1",10.0,1,)   
    # ask the user to enter radius of the cylinder
    rCyl = rs.GetReal("please, enter the radius of the cylinder Cl1",1.0,1,)  
    # ask the user to enter height of the cylinder
    hCyl = rs.GetReal("please, enter the height of the cylinder Cl1",20.0,1,) 
    # ask the user to enter radius of the spehere
    rSph = rs.GetReal("please, enter the radius of the spehere S1",6.0,1,)    
    # ask the user to enter thickness of the slot 
    thSl = rs.GetReal("please, enter the thickness of the slot Sl1",0.3,0.1,)   
    # ask the user to enter height of the slot
    hSl = rs.GetReal("please, enter the height of the slot Sl1",1.3,0.5,)   
 
    # store base point coordiantes

    bx = BasePoint.X
    by = BasePoint.Y
    bz = BasePoint.Z

    # Validation of input
    
    while (thSl < lCube and hSl < lCube and rSph >= lCube/2) == False:
        print ("The thickness of the slot" + " = " + str(thSl)  + "should not be smaller than the length of the cube" + " = " + str(lCube))
        print ("and the height of the slot" + " = " + str(thSl)  + "should not be smaller than the length of the cube" + " = " + str(lCube))
        print ("and the radius of the sphere" + " = " + str(rSph) + "should not be smaller than the half side length of the cube" + " = " + str(lCube/2))
        print ("please, repeat and make sure, that your input matches these criteria")
        return
 
 #create a cylinder
  
    rs.AddCylinder(BasePoint,hCyl,rCyl,cap=True)
 
#create a sphere
    
    rs.AddSphere(BasePoint,rSph)

One problem is that I am not really sure, what "return" exactly does here. The second problem is that neither sphere nor cylinder are created in Rhino!!

Thanks alot!!
