我有以下代码:

level = {0, 0, 0,
         0, 1, 0,
         0, 0, 0}

class player:
    def getPlayerLoc(self, level):
        for i in level:
            if level[level.index(i)] == 1:
                print "Player location = " + str(i)


p1 = player()
p1.getPlayerLoc(level)

Traceback (most recent call last):
  File "gamy.py", line 13, in <module>
    p1.getPlayerLoc(level)
  File "gamy.py", line 8, in getPlayerLoc
    if level[level.index(i)] == 1:
AttributeError: 'set' object has no attribute 'index'

最佳答案

level = {0, 0, 0,
         0, 1, 0,
         0, 0, 0}

level = [0, 0, 0,
         0, 1, 0,
         0, 0, 0]

>>> level = {0, 0, 0,
         0, 1, 0,
         0, 0, 0}
>>> level
{0, 1}  # because set only contains unique elements

>>> level = [0, 0, 0,
         0, 1, 0,
         0, 0, 0]
>>> level
[0, 0, 0, 0, 1, 0, 0, 0, 0]

关于python - 我类的数组给我一个错误……AttributeError : 'set' object has no attribute 'index' ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10788734/
