如何使用python将列表的一些值放入字典中？

我有一个清单（见清单），我想把它送到字典里

但我不想发送所有数据。只是一些值（请参见一些值/特性），这些值会重复多次。例如，“Model:xxx”一词出现了7次。“xxx”是模型的名称，它将更改

到目前为止，我只能在字典中输入列表中的最后一个值。如何将列表中的所有值放入字典

一些价值观：

标签：xxxx

型号：xxxx

图片：xxxx

推断：xxxx

分数：xxxx

TPU_温度（°C）：xxxx

时间（毫秒）：xxx--有两个，我不知道是否可以只提取第二个。但如果不是，也没问题。两者都提取就可以了--

这是代码-尝试1

#this is to match tha values/features that I want to extract
regex = re.compile(r'(\w+)\((.+)\):\s(.*)|(\w+:)\s(.*)')
match_regex = list(filter(regex.match, output))
match = [line.rstrip('\n') for line in match_regex]

features_wanted='ModelImageTime(ms)InferenceScoreTPU_temp(°C)'


#Removing whitespaces and splitting data into "key:value"
#Sending the values/features into a dictionary
dct={i.replace(' ','').split(':')[0]:i.replace(' ','').split(':')[1] for i in match if i.replace(' ','').split(':')[0] in features_wanted}
print(dct, '\n')

这是我用代码得到的字典-尝试1

#this is to match tha values/features that I want to extract
regex = re.compile(r'(\w+)\((.+)\):\s(.*)|(\w+:)\s(.*)')
match_regex = list(filter(regex.match, output))
match = [line.rstrip('\n') for line in match_regex]

features_wanted='ModelImageTime(ms)InferenceScoreTPU_temp(°C)'


#Removing whitespaces and splitting data into "key:value"
#Sending the values/features into a dictionary
dct={i.replace(' ','').split(':')[0]:i.replace(' ','').split(':')[1] for i in match if i.replace(' ','').split(':')[0] in features_wanted}
print(dct, '\n')

仅显示列表的最后一个值

这是代码-尝试2

regex = re.compile(r'(\w+)\((.+)\):\s(.*)|(\w+:)\s(.*)')
match_regex = list(filter(regex.match, data))
match = [line.rstrip('\n') for line in match_regex]

dixie=dict(list(enumerate(match)))

这是我在代码尝试2中得到的字典

regex = re.compile(r'(\w+)\((.+)\):\s(.*)|(\w+:)\s(.*)')
match_regex = list(filter(regex.match, data))
match = [line.rstrip('\n') for line in match_regex]

dixie=dict(list(enumerate(match)))

在这里，我把所有的清单都输入字典。但我没有删除空格，也没有将数据划分为“key:value”

列表（原始列表如下所示）

这是列表（因此您可以进行测试）

如果我正确理解了您的问题（理解您真正想要的是什么有点困难），这段代码将很高兴地将所有数据放入列表中：

from pprint import pprint
from collections import defaultdict

lines = [
    "labels: imagenet_labels.txt ",
    "Model: efficientnet-edgetpu-S_quant_edgetpu.tflite ",
    "Image: insect.jpg ",
    "Time(ms): 23.1",
    "Time(ms): 5.7",
    "Inference: corkscrew, bottle screw",
    "Score: 0.03125 ",
    "TPU_temp(°C): 57.05",
    "labels: imagenet_labels.txt ",
    "Model: efficientnet-edgetpu-M_quant_edgetpu.tflite ",
    "Image: insect.jpg ",
    "Time(ms): 29.3",
    "Time(ms): 10.8",
    "Inference: dragonfly, darning needle, devil's darning needle, sewing needle, snake feeder, snake doctor, mosquito hawk, skeeter hawk",
    "Score: 0.09375 ",
    "TPU_temp(°C): 56.8",
    "labels: imagenet_labels.txt ",
    "Model: efficientnet-edgetpu-L_quant_edgetpu.tflite ",
    "Image: insect.jpg ",
    "Time(ms): 45.6",
    "Time(ms): 31.0",
    "Inference: pick, plectrum, plectron",
    "Score: 0.09766 ",
]

values = defaultdict(list)

for line in lines:
    key, value = line.split(": ", 1)
    values[key].append(value)

pprint(dict(values))

打印出来

{'Image': ['insect.jpg ', 'insect.jpg ', 'insect.jpg '],
 'Inference': ['corkscrew, bottle screw',
               "dragonfly, darning needle, devil's darning needle, sewing "
               'needle, snake feeder, snake doctor, mosquito hawk, skeeter '
               'hawk',
               'pick, plectrum, plectron'],
 'Model': ['efficientnet-edgetpu-S_quant_edgetpu.tflite ',
           'efficientnet-edgetpu-M_quant_edgetpu.tflite ',
           'efficientnet-edgetpu-L_quant_edgetpu.tflite '],
 'Score': ['0.03125 ', '0.09375 ', '0.09766 '],
 'TPU_temp(°C)': ['57.05', '56.8'],
 'Time(ms)': ['23.1', '5.7', '29.3', '10.8', '45.6', '31.0'],
 'labels': ['imagenet_labels.txt ',
            'imagenet_labels.txt ',
            'imagenet_labels.txt ']}

但是，如果行的顺序很重要（例如，每个“标签：”开始一个新的组），那么很可能您想要类似的东西

# Initialize our list of groups; add in an empty group
# to make the future code easier.
groups = [{}]

for line in lines:
    # Split each line in 2 parts (1 split) on `: `
    key, value = line.split(": ", 1)
    if key == "labels":  # If the key is labels, it starts a new group.
        if groups[-1]:  # If there is something in the current (last) group,
            groups.append({})  # ... add a new one.
    # No matter what, add the key-value pair to the last group.
    groups[-1][key] = value

pprint(groups)

输出

[{'Image': 'insect.jpg ',
  'Inference': 'corkscrew, bottle screw',
  'Model': 'efficientnet-edgetpu-S_quant_edgetpu.tflite ',
  'Score': '0.03125 ',
  'TPU_temp(°C)': '57.05',
  'Time(ms)': '5.7',
  'labels': 'imagenet_labels.txt '},
 {'Image': 'insect.jpg ',
  'Inference': "dragonfly, darning needle, devil's darning needle, sewing "
               'needle, snake feeder, snake doctor, mosquito hawk, skeeter '
               'hawk',
  'Model': 'efficientnet-edgetpu-M_quant_edgetpu.tflite ',
  'Score': '0.09375 ',
  'TPU_temp(°C)': '56.8',
  'Time(ms)': '10.8',
  'labels': 'imagenet_labels.txt '},
 {'Image': 'insect.jpg ',
  'Inference': 'pick, plectrum, plectron',
  'Model': 'efficientnet-edgetpu-L_quant_edgetpu.tflite ',
  'Score': '0.09766 ',
  'Time(ms)': '31.0',
  'labels': 'imagenet_labels.txt '}]

这个错误不是来自你发布的代码。你是对的！下面我有一些未注释的单词。@Aizzaac

fr

是一个原始的f字符串。f字符串用于将变量替换为字符串，这里不需要。您可以使用

defaultdict（list）

和附加值，但不确定它是否是您要查找的。同一个键在字典中不能有两次。选项2似乎是正确的。我的目标是将数据发送到elasticearch。我将测试它是否有效。它似乎有效。这是我放置结果的另一个链接：

添加了注释，希望对您有所帮助。
