Accept Keyboard Input

(Menu)   A   B   C   D   E   F   G   H   I
Replace the break with the 3 final lines shown.
The final line is also a break but indented further.

#     print '  0 - Exit'     print     raw_input("  Press 'Enter' to close: ")     if option == '0':         break #

Entering 0 is now the only way to exit the loop from keyboard.
Any other input, including Enter alone, is ignored.
