python3读取yaml文件

将通用内容存放在yaml中，替换时只需要yaml文件即可。

host.yaml

host: 10.96.82.148

readYaml.py

# -*- coding:utf8 -*-

import os
import yaml

current_path = os.path.abspath(os.path.dirname(__file__)) //获取当前地址
print(current_path + "/host.yaml") //拼接yaml文件位置

hostPath = current_path + "/host.yaml"

def returnHost():
    with open(hostPath, 'r') as f:
        temp = yaml.safe_load(f.read())
        print(temp)
        print(temp['host'])
    return temp['host']

if __name__ == '__main__':
    returnHost()
