Question

我正在尝试在字典中获取名称及其相应的键值。对不起，如果已经问过这个问题。这段代码不起作用，因为我吮吸编程并刚开始。请告诉我它有什么问题。

theBoard = {'top-L': ' ',
'top-M': ' ',
'top-R': ' ',
'mid-L': ' ',
'mid-M': ' ',
'mid-R': ' ',
'low-L': ' ',
'low-M': ' ',
'low-R': ' '

'Check for closed moves'
def openMoves:
    for i in theBoard:
        if theBoard[i] == ' ':
            print "the move %s is open" % theBoard[i]
        else:
            print "the move %s is taken" % theBoard[i]
print openMoves()

Answer 1

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

Answer 2

theBoard = {'top-L': ' ',
    'top-M': ' ',
    'top-R': ' ',
    'mid-L': ' ',
    'mid-M': ' ',
    'mid-R': ' ',
    'low-L': ' ',
    'low-M': ' ',
    'low-R': ' '}

def openMoves():
    for k,v in theBoard.items():
        if v == ' ':
            print "the move %s is open" %k
        else:
            print "the move %s is taken" %k
