我正在尝试弄清楚如何打印包含3 storeItems
的列表OrderedDict()
,并且能够为每个列表打印key
和value
OrderedDict
。我不知道如何解决这个问题,这就是我试过的,它给了我一个TypeError: string indices must be integers
。
storeItems = [{}, {}, {}]
storeItems[0] = OrderedDict()
storeItems[1] = OrderedDict()
storeItems[2] = OrderedDict()
storeItems[0]['Name'] = 'Auto-Enter'
storeItems[0]['Price'] = 30
storeItems[0]['Max'] = 100
storeItems[1]['Name'] = 'Multiplier'
storeItems[1]['Price'] = 100
storeItems[1]['Max'] = 5
storeItems[2]['Name'] = 'Factory'
storeItems[2]['Price'] = 100
storeItems[2]['Max'] = 3
#the original layout of the storeItems
#storeItems = [{
# "Name": "Auto-Enter",
# "Price": 30,
# "Max": 100
# }, {
# "Name": "Multiplier",
# "Price": 100,
# "Max": 5
# }, {
# "Name": "Factory",
# "Price": 200,
# "Max": 3
# }]
i = 0
for value in storeItems:
for key in value:
for i in range(0, 2):
print(storeItems[i][key], storeItems[i][key][value])
我发现,for value in storeItems: print(value)
会为每一行打印OrderedDict([('Name': 'Auto-Enter', ...)])
。 print(storeItems[0]['Name'])
输出Auto-Enter
。我似乎很难把它变成循环。
我更喜欢这样做尽可能接近storeItems
答案 0 :(得分:2)
storeItems
中的每个元素都是一个字典(OrderedDict
只是跟踪插入顺序的子类),所以只需循环遍历dict.items()
method:
for odict in storeItems:
for key, value in odict.items():
print(key, value)
