需安装python_nmap包，支持2.x以及3.x
python_nmap包提供了python调用nmap的一系列接口 （一）重要类及方法：
1.创建nmap扫描器
class PortScanner()
__init__(self, nmap_search_path=('nmap', '/usr/bin/nmap', '/usr/local/bin/nmap', '/sw/bin/nmap', '/opt/local/bin/nmap'))
Initialize PortScanner module * detects nmap on the system and nmap version
* may raise PortScannerError exception if nmap is not found in the path :param nmap_search_path: tupple of string where to search for nmap executable. Change this if you want to use a specific version of nmap.
:returns: nothing
2.扫描器方法
scan(self, hosts='127.0.0.1', ports=None, arguments='-sV', sudo=False)
Scan given hosts May raise PortScannerError exception if nmap output was not xml Test existance of the following key to know if something went wrong : ['nmap']['scaninfo']['error']
If not present, everything was ok. :param hosts: string for hosts as nmap use it 'scanme.nmap.org' or '198.116.0-255.1-127' or '216.163.128.20/20'
:param ports: string for ports as nmap use it '22,53,110,143-4564'
:param arguments: string of arguments for nmap '-sU -sX -sC'
:param sudo: launch nmap with sudo if True :returns: scan_result as dictionnary （二）例子
import nmap
scanner = nmap.PortScanner() #nmap_search_path已包含了nmap所在路径，若默认路径中没有nmap,则需指出
results = scanner.scan(hosts='192.168.2.1',ports='80')
pprint.pprint(results)

运行后的结果为：

扫描语句是： nmap -oX - -p 80 -T4 -A -v -Pn 192.168.1.1
