循环使用字典并获取密钥
这个问题在这里已经有了答案：
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
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
我认为你的绊脚石也是...
