在yaml中查找嵌套的键值对

import yaml

def find_key_value_pairs(data, target_key):
    result = []
    if isinstance(data, dict):
        for key, value in data.items():
            if key == target_key:
                result.append((key, value))
            elif isinstance(value, dict):
                result.extend(find_key_value_pairs(value, target_key))
    elif isinstance(data, list):
        for item in data:
            result.extend(find_key_value_pairs(item, target_key))
    return result

# 加载yaml文件
with open('example.yaml', 'r') as file:
    yaml_data = yaml.safe_load(file)

# 查找键值对
target_key = 'key2'
key_value_pairs = find_key_value_pairs(yaml_data, target_key)

# 打印结果
for key, value in key_value_pairs:
    print(f"Key: {key}, Value: {value}")
