Question about functions

[Aubrey Hutchison]

Question about functions:

1)--- module "A" contains the following
 X          = 999666       #easy to notice value
 Y          = 111222       #easy to notice value
 Product = 69696969   #easy to notice value

 def  DoSomething():
      global Product,X,Y
      Product = X*Y
      return 0

 module imported
 from A import *

2)--- toplevel code

 def Mult():
      global Product,X,Y
      DoSomething():
      return 0

 """start of top level code """
 ...
 ...
 Product =Mult()
 ...
 print Product   (      Result   ----> print out is 69696...)

Per "Python Nutshell" this appears to be the correct result.
How do you or can you modify the imported variables without using
classes objects?
