python3 yaml

安装 yaml

pip3 install PyYaml

yaml文件示例

data.yaml

user_name: 'aa'
pwd: '123456'
header: {'X-Requested-With': 'XMLHttpRequest'}
di: 4
stock: 1
buy_type: 'goods'
address_id: 2
payment_id: 1
spec: ''
user_note: ''

yaml 存储结构如上，name +:+空格，后面可以是对象、字符串、bool值、整数、浮点数、时间、日期、null等

将数据写入 yaml 文件中

import yaml

data = {'name': 'Lex',
            'department': 'SQA',
            'salary': 8000,
            'annual leave entitlement': [5, 10]}

with open('write_yaml.yaml','w',encoding='utf-8') as f:
    yaml.dump(data,f)

读取 yaml 文件数据

f = open('data.yaml', 'r', encoding='utf-8')
data = yaml.safe_load(f)
#获取 user_name
user_name=data['user_name']
print(user_name)

打印结果
