python - Python 文本文件中的字典

Question

问题:

我有一个这种格式的 txt 文件:

Intestinal infectious diseases (001-003)  
001 Cholera  
002 Fever  
003 Salmonella   
Zoonotic bacterial diseases (020-022)  
020 Plague  
021 Tularemia  
022 Anthrax  
External Cause Status (E000)  
E000 External cause status  
Activity (E001-E002)  
E001 Activities involving x and y  
E002 Other activities

以 3 整数代码/E+3 整数代码/V+3 整数代码开头的每一行都是前一个标题的值，它们是我的字典的键。在我看到的其他问题中，可以使用列或冒号来解析每一行以生成键/值对，但我的 txt 文件的格式不允许我这样做。

有没有一种方法可以将这样的 txt 文件制作成字典，其中键是组名，值是代码+疾病名称？

我还需要将代码和疾病名称解析到第二个字典中，所以我最终得到一个字典，其中包含组名作为键，值是第二个字典，代码作为键，疾病名称作为值。

脚本:

def process_file(filename):
    myDict={}
        f = open(filename, 'r')
        for line in f:
            if line[0] is not int:
                if line.startswith("E"):
                    if line[1] is int:
                        line = dictionary1_values
                    else:
                        break
                else:
                    line = dictionary1_key
            myDict[dictionary1_key].append[line]

期望的输出格式是:
{“肠道传染病(001-003)”:{“001”:“霍乱”，“002”:“发烧”，“003”:“沙门氏菌”}，“人畜共患细菌性疾病(020-022) ": {"020": "鼠疫", "021": "Tularemia", "022": "炭疽病"}, "外因状态(E000)": {"E000": "外因状态"}, "事件(E001-E002)”:{“E001”:“涉及x和y的事件”，“E002”:“其他事件”}}

def process_file(filename):
    myDict = {}
    rootkey = None
    f = open(filename, 'r')
    for line in f:
        if line[1:3].isdigit():           # if the second and third character from the checked string (line) is the ASCII Code in range 0x30..0x39 ("0".."9"), i.e.: str.isdigit()
            subkey, data = line.rstrip().split(" ",1)     # split into two parts... the first one is the number with or without "E" at begin
            myDict[rootkey][subkey] = data
        else:
            rootkey = line.rstrip()       # str.rstrip() is used to delete newlines (or another so called "empty spaces")
            myDict[rootkey] = {}          # prepare a new empty rootkey into your myDict
    f.close()
    return myDict

在 Python 控制台中测试:

>>> d = process_file('/tmp/file.txt')
>>>
>>> d['Intestinal infectious diseases (001-003)']
{'003': 'Salmonella', '002': 'Fever', '001': 'Cholera'}
>>> d['Intestinal infectious diseases (001-003)']['002']
'Fever'
>>> d['Activity (E001-E002)']
{'E001': 'Activities involving x and y', 'E002': 'Other activities'}
>>> d['Activity (E001-E002)']['E001']
'Activities involving x and y'
>>>
>>> d
{'Activity (E001-E002)': {'E001': 'Activities involving x and y', 'E002': 'Other activities'}, 'External Cause Status (E000)': {'E000': 'External cause status'}, 'Intestinal infectious diseases (001-003)': {'003': 'Salmonella', '002': 'Fever', '001': 'Cholera'}, 'Zoonotic bacterial diseases (020-022)': {'021': 'Tularemia', '020': 'Plague', '022': 'Anthrax'}}

警告:文件中的第一行必须只是一个“rootkey”!不是“子键”或数据!否则原因可能是引发错误:-)

注意:也许您应该删除第一个“E”字符。还是做不到？您需要在某处留下这个“E”字符吗？
