Python常用配置文件ini、json、yaml读写总结

import configparser

#使用前，需要创建一个实例
config = configparser.ConfigParser()
#读取并打开文件
config.read('test.ini',encoding='utf-8')
#获取sections,返回列表
print(config.sections())
#[db,data]
#获取sections下的所有options
print(config.options('db'))
#['user', 'pwd', 'host', 'database', 'port']
#获取指定section下指定的options
print(config.get('db','user'))
# root
#获取section中所有键值对
print(config.items('data'))
#[('admin_user', 'tong'), ('admin_pwd', '123456')]
#删除整个section
config.remove_section('data')
#删除某个section下的key
config.remove_option('db','host')
print(config.items('db'))

import configparser

config=configparser.ConfigParser()
config['url']={'url':'www.baidu.com'} #类似于字典操作

with open('example.ini','w') as configfile:
    config.write(configfile)

{
  "name":"smith",
  "age":30,
  "sex":"男"
}

# 读取json
import json
with open('test1.json') as f:
    a = json.load(f)
print(a)

# 写入json
import json
dic ={
    "name" : "xiaoming",
    "age" : 20,
    "phonenumber" : "15555555555"
}

with open("test2.json", "w") as outfile:
    json.dump(dic, outfile)

case1:
 info:
  title: "正常登陆"
  url: Http://192.168.1.1/user/login
  method: "POST"
 json:
  username: "admin"
  passWord: "123456"
 expected:
  status_code: 
  - 200
  - 300
  content: "user_id"

pip install pyyaml

import yaml
with open("testyaml.yaml", encoding='utf-8') as file:
    data = yaml.safe_load(file)
    print(data)
    print(data['case1']['json'])
    print(data['case1']['json']['username'])

import yaml
#定义一个字典

content = {
    'id': 1,
    'text': 'programming languages',
    'members': ['java', 'python', 'python', 'c', 'Go', 'shell'],
    'next': {'a':1,'b':2}
}

with open('test3.yaml', 'w', encoding='utf-8') as file:
    yaml.dump(content, file, default_flow_style=False, encoding='utf-8', allow_unicode=True)
