import sys
    import load_rule.yaml

    yaml_str = """\
    Get_Request:
      alias : 'amway1'
      session_url : 'url2'

    Post_Request:
      alias : 'amway2'
      session_url : 'url2'

    yaml = load_rule.yaml.YAML()
    try:
        data = yaml.load(yaml_str)
    except Exception as e:
        print(e)

另一种方式

import yaml

file_name = 'load_rule.yml'

with open(file_name) as infile:
    data = yaml.load(infile)

person = data['Person']
person['name'] = input('What is your name? ')
person['age'] = int(input('What is your age? '))
person['nationality'] = input('What is your nationality? ')
person['footed'] = input('What foot? ')
person['position'] = input('What is your position? ')

with open(file_name, 'w') as outfile:
    yaml.dump(data, stream=outfile, default_flow_style=False, indent=3)

在这里你可以根据你需要修改python代码，在python中打开yaml文件，将数据保存到数组中，进行对象查询并执行测试任务。
