[Tutor] Calling Program within Program

[patty at cruzio.com]

Hello:

I would like to know how to call a program from within a program and what
directory I should place one small program file in.  I am running Python
2.6.6 and Windows 7.

I have a directory called  C:\Users\StarShip\PyProgs and it has the files
BreakersCafe.txt and BreakersCafe.py.  This is my primary program running
fine.

I have a subdirectory called C:\Users\StarShip\PyProg \PicturesForTesting
and another subdirectory C:\Users\StarShip\PyProgs\CustomFunctions with
various program files, functions defined  in them, etc.  which I import in
my primary program.   For example:

 def Newbanner():
    print "\n                       Alternate Selections\n"

Now I have the small program below which is fully self-contained and I
want to execute it from within  BreakersCafe.txt. I would like to use
raw_input and if statement for simple yes/no asking if they would like to
see this BeveragesMenu.txt and have it as the last 3-4 lines of the
main().

The only directory of these three that has __init__ is
   C:\Users\StarShip\PyProgs\CustomFunctions
and as you can see, the program below is not a function, it has no 'def'
anything.  I get 'NameError: global name 'BeveragesMenu' is not defined'
when I run this in IDLE.  I suppose I _could_ make this a function :} but
it is likely doable to call a program as a program, right?  I am also
compiling to a .pyw file where applicable.

Thanks for the help.

Patty
