1、将上述prt_cmd_color.py文件放在与待执行脚本ping_ip.py同一目录下。或者通过sys.path.append()将prt_cmd_color.py文件所在的目录添加到搜索路径下。 2、ping_ip.py脚本中import prt_cmd_color导入模块或者执行from prt_cmd_color import printGreen, printRed导入指定函数。 3、ping_ip.py代码内容如下: i...

三个参数的意义分别起始位置,终止位置和步长，同时要注意，切片操作并不涉及最后的终止位置所在的那个元素。因此1:4:2表示从1开始取到3(4-1),步长为2，因此对应的下标为1和3。所以color[1:4:2]也就是取color中下标为1和3对应元素的值(注意Python中下标从0开始,也就是说对应取第2和第4个元素)...
