python - 如何解析复杂的字符串

转载作者：行者123 更新时间：2023-11-30 23:38:00

我正在尝试解析以下字符串(实际上这是一个列表，无论如何......)。

我想在这里使用 re 但也许有一个简单的解决方案？我的大脑今天看到了太多代码。

最好将所有信息存储在一个 dict() 中

{'title1': 
    {'duration': '02:06:44', 
     'audio_tracks': 
         [{'1': 'English (AC3) (5.1 ch) (iso639-2: eng), 48000Hz, 384000bps' },
         {'2': 'English (AC3) (Dolby Surround) (iso639-2: eng), 48000Hz, 192000bps' },
         ...]},
     'subtitle_tracks':
         [{'1': 'English (iso639-2: eng) (Bitmap)(VOBSUB)' },
         {'2': 'Deutsch (iso639-2: deu) (Bitmap)(VOBSUB)' },
         ...]},
     }
}

类似这样的事情。也许有人有一些如何解析的提示:

+ something:
    + some: info,
    + something:,
        + 1: indented information

东西？

最佳答案

我有一个小的缩进文本解析器，我将其用于各种目的。这里我将其适配为ffmpeg格式:

import sys
import re

root = ['root', []]
path = [root]
last_indent = -1
for line in sys.stdin:
    line = line.rstrip()
    if not line:
        break

    # calculate indent
    iline = line
    line = line.lstrip(' ')
    indent = (len(iline) - len(line))/2

    line = line.lstrip('+ ')
    bits = re.split('[:,]', line, 1)
    key = bits[0]
    try:
        content = bits[1].strip()
    except IndexError:
        content = None

    if not content:
        # root node
        content = []

    if indent <= last_indent:
        del path[indent - last_indent - 1:]
    cur = [key, content]
    path[-1][-1].append(cur)
    path.append(cur)
    last_indent = indent

pprint(root)

输出:
