如何用Python解析文本文件的特定块并导出json格式

import json

def parse_text_file(file_path):
    data = []
    with open(file_path, 'r') as file:
        block = {}
        for line in file:
            if line.strip() == "START":
                block = {}
            elif line.strip() == "END":
                data.append(block)
            else:
                key, value = line.strip().split(":")
                block[key] = value
    return data

def export_to_json(data, json_file_path):
    with open(json_file_path, 'w') as json_file:
        json.dump(data, json_file)

# 调用示例
text_file_path = "path/to/text_file.txt"
json_file_path = "path/to/output.json"

parsed_data = parse_text_file(text_file_path)
export_to_json(parsed_data, json_file_path)
