使用python读取yaml文件：

yaml文件数据：data.yaml

login_data:
  url: 'http://www.baidu.com'

case1:
  user1: ''
  password1: '12345'
  errorText: '请输入用户名'

case2:
  user2: 'admin'
  password2: ''
  errorText: '请输入密码'

case3:
  user3: 'admin'
  password3: '123456'
  errorText: '登录成功'

python读取yaml文件数据：

# coding = utf-8

import yaml
#方式一：
with open('data.yaml', mode='r', encoding='utf-8') as f:
    msg = yaml.safe_load(f)
    print(msg)

#方式二：
stream = open('data.yaml', mode='r', encoding='utf-8')
msg = yaml.safe_load(stream)
print(msg)
stream.close()

读取结果：
