1.前提是:windows已经配置好Python的环境变量;
2.进入cmd命令行模式:
**输入python命令,检测是否环境配置好:显示这样说明配置环境变量没问题
**用cd命令进入Python脚本所在的目录:
**Python脚本所在目录下输入命令:python "这里直接把python脚本拖拽过来" 后边加参数:
**脚本的代码问题可能导致,cmd命令行下运行脚本后没有任何反应,所以务必检查脚本正确:
**这里要说明的是可以使用print()函数逐行检测代码,输出对应的参数;
**Python3下的:
if (): //if后边必须跟else才能执行
else:
下面是一个Python脚本写的端口扫描器:

from socket import * def connScan(tgtHost,tgtPort):
try:
connSkt=socket(AF_INET,SOCK_STREAM)
connSkt.connect((tgtHost,tgtPort))
connSkt.send('ViolentPython\r\n')
results=connSkt.recv(100)
print('[+] %d/tcp open'% tgtPort)
print('[+]'+str(results))
connSkt.close()

exit(0)
else:
portScan(tgtHost,tgtPorts)
if __name__=='__main__':
main() 运行结果如下:
