如何通过使用python从嵌套的yaml中搜索来打印第一个键

import yaml

with open('file.yaml', 'r') as f:
    data = yaml.safe_load(f)

def search_key(data):
    if isinstance(data, dict):
        for key, value in data.items():
            print(key)
            search_key(value)

search_key(data)

import yaml

def search_key(data):
    if isinstance(data, dict):
        for key, value in data.items():
            print(key)
            search_key(value)

with open('file.yaml', 'r') as f:
    data = yaml.safe_load(f)

search_key(data)

pip install pyyaml
