theBoard = {'top-L': ' ',
    'top-M': ' ',
    'top-R': ' ',
    'mid-L': ' ',
    'mid-M': ' ',
    'mid-R': ' ',
    'low-L': ' ',
    'low-M': ' ',
    'low-R': ' '
}                                             # <--- Close your dictionary

                                              # <--- remove random string 'Check for c...'
def openMoves():                              # <--- add parenthesis to function
    for k, v in theBoard.items():             # <--- loop over the key, value pairs
        if v == ' ':
            print "the move %s is open" % k
        else:
            print "the move %s is taken" % k

openMoves()                                   # <-- remove the print statement

我认为你的绊脚石也是...
