你的问题很简单，我在不到五分钟的时间里就为它写了工作代码，一气呵成。
您有一些表示Map的行，这些行可以包含冒号，包含冒号的行表示新键值对的开始。
键位于冒号的左侧，值可以跨多行。
我们可以分配一个名为key的变量，将其初始化为None。然后，我们循环遍历这些行，对于每一行，如果我们找到一个冒号并且第一个字符不是空格，那么我们就找到了一个新的键值对。
如果key不是None，我们将之前的键值对添加到字典中。然后，我们设置要记住的当前键值对，并在以后的迭代中使用它们。
然后，如果该行不是空的，也不是一个新对的开始，它是前一个值的延续，我们把它加到前一个值上。
这样我们就可以正确地处理所有项目，但我们会错过最后一个项目。
我们可以稍后添加它。

你可以使用re（text包含你的问题中的字符串）（regex101）：

import re

out = dict(re.findall(r"^(\S+):\s*(.*?)(?=^\S*:|\Z)", text, flags=re.M | re.S))
print(out)

你的档案是yaml
要使用yaml文件，您需要库ruamel.yaml

安装

pip install ruamel.yaml

字符串

加载文件并转换为json编写json

from ruamel.yaml import YAML
import json
yaml=YAML(typ='safe')   # default, if not specfied, is 'rt' (round-trip)
filename = 'thunar-volman/debian/control'
dict1 = {}
with open(filename) as fh:
    dict1 = yaml.load(filename)
with open("test.json", "w") as out_file:
    json.dump(dict1, out_file, indent=4, sort_keys = False)

使用maxsplit或Python String split() Method。

from pathlib import Path
import json

with Path('control').open() as file:   # be sure to adjust your path
    commands, description = {}, ''
    for line in file:
        if not line.strip(): continue  # if line is blank continue loop
        if ':' in line:
            # use 'maxsplit=1' to split only the first occurance of ':'
            command, description = list(map(str.strip, line.split(':', maxsplit=1)))
        else:
            # if not ':' in line append line to description
            description += ' %s' % line.strip()
        commands[command] = description

你可以这样做：

import json
filename = 'thunar-volman/debian/control'
dict1 = {}
command = ""
description = ""
with open(filename) as fh:
    for line in fh:
        print(line)
        if line[0] == " ":
            description = line.strip()
            dict1[command.strip()].append(description.strip())
        else:
            command, description = line.strip().split(': ')
            dict1[command.strip()] = description.strip()

with open("test.json", "w") as out_file:
    json.dump(dict1, out_file, indent=4, sort_keys = False)

因此，基本上，如果在开始处有一个白色，那么它将在前一个命令中追加新项。

打开文件并逐行读取。忽略空行。在冒号上拆分，检查标记的数量。确保输入数据的完整性

from json import dumps

CONTROL = '/Volumes/G-Drive/control'

jdata = {}

with open(CONTROL) as control:
    previous_key = None
    for line in control:
        if len(sline := line.strip()) > 0: # make sure to skip blank lines
            if line[0].isspace():
                if previous_key is not None:
                    # you may not want the newline prefix
                    jdata[previous_key] += '\n' + sline
                else:
                    raise ValueError('Line has leading whitespace but no previous keyword')
            elif len(tokens := sline.split(':', 1)) == 2: # note second argument to split()
                # looks like a normal keyword and value
                key, value = tokens
                jdata[key] = value.lstrip()
