python配置文件
1、经试验以“.yml”结尾的配置文件更好用。虽然以“.yaml”也可以使用，但是坑太多，不建议使用
2、yaml配置文件规则写法如下：
yaml基本语法
1、大小写敏感
2、使用缩进表示层级关系
3、缩进时不允许使用tab，是允许使用空格
4、缩进时空格数目不重要，只要相同层级的元素左对齐即可
5、# 表示注释，从它开始到行尾被忽略
6、使用 --- 来进行每条信息的区别

# 这个例子输出一个字典，其中value包括所有基本类型
str: "Hello World!"
int: 110
float: 3.141
boolean: true # or false
None: null # 也可以用 ~ 号来表示 null
# 使用strftime()方法来格式化时间参数
time: '2016-09-22 03:43:30'

# 如果字符串没有空格或特殊字符，不需要加引号，但如果其中有空格或特殊字符，则需要加引号了
str: 灰蓝
str1: "Hello World"
str2: "Hello\nWorld"

# 这里要注意单引号和双引号的区别，单引号中的特殊字符转到Python会被转义，也就是到最后是原样输出了，双引号不会被Python转义，到最后是输出了特殊字符
str1: 'Hello\nWorld'
str2: "Hello\nWorld"

# & 和 * 用于引用
