替换yaml文件python中的标记

import yaml

def replace_yaml_tag(file_path, old_tag, new_value):
    with open(file_path, 'r') as file:
        data = yaml.safe_load(file)

    updated_data = replace_tag_recursively(data, old_tag, new_value)

    with open(file_path, 'w') as file:
        yaml.safe_dump(updated_data, file)

def replace_tag_recursively(data, old_tag, new_value):
    if isinstance(data, dict):
        for key, value in data.items():
            if key == old_tag:
                data[key] = new_value
            else:
                data[key] = replace_tag_recursively(value, old_tag, new_value)
    elif isinstance(data, list):
        for index, item in enumerate(data):
            data[index] = replace_tag_recursively(item, old_tag, new_value)
    
    return data

# 使用示例
replace_yaml_tag('config.yaml', 'version', '1.2.3')
