一、map将传入的函数依次作用到序列的每个元素，并把结果作为新的Iterator返回，范例：

[code language=”python”]

list_a=[1,3,5,1,2,3]
map(str, [1, 2, 3, 4, 5, 6, 7, 8, 9])
map(str, [item for item in list_a])   #循环将每个元素转换为字符串
[str(item) for item in list_a]             # 也可以简化成左边格式

[/code]

1.  安装
   1.  yum install python3
   2. yum install chromedriver
   3. yum install chromium

2. 测试程序

理论上嵌入式版本不能单独作为运行环境，但是本人一向不喜欢安装.exe，怕环境被污染，参考网上一些文章之后，初步能运行起来，还未详细调试

1. install dependencies
   1. yum install nginx
   2. yum install wget
2. open firewall
   1. firewall-cmd –permanent –zone=public –add-port=http/tcp
   2. firewall-cmd –permanent –zone=public –add-port=https/tcp
   3. firewall-cmd –reload
