your use of excessive whitespace doesn't exactly make it easier to read 
your code...  I suggest reading PEP 8.

when you write

     command=Hide_Show_2D(hs)

Python will *call* the function, take the return value from the 
function, and pass *that* to the Radiobutton.  try inserting a
lambda:

     command=lambda: Hide_Show_2D(hs)

("lambda: expression" creates an anonymous function that evaluates the 
expression when called).

since "value" is a Tkinter StringVar, you have to replace the test with

     value.get() == '2'

(alternatively, change the lambda to "lambda: Hide_Show_2D(hs.get())")
