在运行时使用文件中的数据在python中创建字典的字典

Question

我们如何在运行时使用python创建字典的下方字典。

当将数据手动存储在字典中时，具有所需输出的附加代码段。

何时从InputFile中获取输入？？？

输入文件

00

称为999000

VLR 365444564544

致电2756565

16

原因码12

4级

严重程度轻微

剧本：

Operation = {'00': {'Called': '999000', 'calling': '2756565', 'vlr': '365444564544'},
                    '16': {'reason_code': '12'}
                   }

for op_id, op_info in Operation.items():
    print("\n Operation ID:", op_id)

    for key in op_info:
        print(key + ':', op_info[key])

OUTPUT

Operation ID: 00

        Called: 999000

        vlr: 365444564544

        calling: 2756565

 Operation ID: 16

             reason_code: 12 

             level :4

             severity :minor

当从InputFile提取Input时，如何在python中创建上述字典的字典？

看起来只有键的行可以通过对其中的单词进行计数来检测，然后可以使用该键直到有新的键为止。 这是一个示例实现：

def file2dict(file_name):
  with open(file_name) as f:
    res = dict()                 # result
    key = ""                     # we keep the key until there is a new one
    for line in f.readlines():
      words = line.split()       # get words in lines
      if (words):                # check if the line was not empty
        if (len(words) == 1):    # if the length is one, we know this is a new key 
          key = words[0]         # and we change the key in use
          res[key] = dict()      # and create a dict element 
        else:
          res[key][words[0]] = words[1]  # and add key-value pairs in each line
return res

测试一下：

print(file2dict("in.txt")) # your example file

输出：

{'00': {'Called': '999000', 'VLR': '365444564544', 'Calling': '2756565'}, '16': {'reason_code': '12', 'level': '4', 'severity': 'minor'}}
