文件只能安装一次

def get_mac_address(): 
    mac=uuid.UUID(int = uuid.getnode()).hex[-12:] 
    return ":".join([mac[e:e+2] for e in range(0,11,2)])

获取计算机名字

import socket
socket.gethostname()

linux下获取主机外网ip

import socket
import fcntl
import struct
def get_ip_address(ifname):
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    return socket.inet_ntoa(fcntl.ioctl(
        s.fileno(),
        0x8915,  # SIOCGIFADDR
        struct.pack('256s', ifname[:15])
    )[20:24])
print get_ip_address('lo')
print get_ip_address('eth0')

win linux兼容模式

import re,urllib2
class Getmyip:
    def getip(self):
        try:
            myip = self.visit("http://www.ip138.com/ip2city.asp")
        except:
            try:
                myip = self.visit("http://www.bliao.com/ip.phtml")
            except:
                try:
                    myip = self.visit("http://www.whereismyip.com/")
                except:
                    myip = "So sorry!!!"
        return myip
    def visit(self,url):
        opener = urllib2.urlopen(url)
        if url == opener.geturl():
            str = opener.read()
        return re.search('\d+\.\d+\.\d+\.\d+',str).group(0)
getmyip = Getmyip()
localip = getmyip.getip()
print localip

获取系统信息

Python里里面有个platform模块，可以得到操作系统的相关信息
import platform
platform.machine()    # Returns the machine type, e.g. 'i386'

platform.node()    # Returns the computer's network name

platform.platform(aliased=0, terse=0)    # Returns a single string identifying the underlying platform

platform.processor()    # Returns the (true) processor name

platform.python_branch()    # Returns a string identifying the Python implementation branch.

platform.python_build()    # Returns a tuple (buildno, builddate) stating the Python build number and date as strings.
    
platform.python_compiler()    # Returns a string identifying the compiler used for compiling Python.

platform.python_version()    # Returns the Python version as string 'major.minor.patchlevel'

platform.release()    # Returns the system's release, e.g. '2.2.0' or 'NT'

platform.system()    # Returns the system/OS name, e.g. 'Linux', 'Windows' or 'Java'.

platform.uname()    # Fairly portable uname interface. Returns a tuple of strings (system,node,release,version,machine,processor) identifying the underlying platform.
        
platform.win32_ver(release='', version='', csd='', ptype='')    # Get additional version information from the Windows Registry and return a tuple (version,csd,ptype) referring to version number, CSD level and OS type (multi/single processor).
