Python implements basic information for Linux operating systems

Get the following information:

Host Name

System version

System Kernel Version

Total Memory

CPU Manufacturers

CPU Total Core Number

Server Manufacturers

Server serial Number

Each NIC Ip,mac and Nic name information

The implementation code is as follows:

The output results are as follows:

These results are not problematic with CentOS 7 and CentOS 6 testing, and some IO errors may occur with other systems
