从包含特殊字符(星号、与符号、*、&)的python dict中写入YAML文件

import yaml
import re

data = {
    'key1': 'value1',
    'key2': '*&somevalue',
    'key3': 'anothervalue*',
    'key4': '&specialvalue&'
}

def escape_special_characters(value):
    value = re.sub(r"([*])", r"\\*", value)
    value = re.sub(r"([&])", r"\\&", value)
    return value

escaped_data = {}
for key, value in data.items():
    escaped_data[key] = escape_special_characters(value)

with open('output.yaml', 'w') as file:
    yaml.dump(escaped_data, file)
