this will only work on a windows machine. It is from C++ runtime lib 
msvcrt.dll


in py module 
import msvcrt

while 1:
    ch = msvcrt.getch()   ## returns one char
    if ch == 'Y' :
       # do stuff or break
        break

    print "%d (%r)"  % (ch, ch)


  # also,  kbhit()  #  returns true if char is available

  # also, ungetch(ch)  # undo char ch
