Question

当我在Python命令提示符下运行命令时，我尝试运行时遇到无效语法错误：-t localhost -p 9999，我的Python IDE版本为2.7.12。

这是我的代码：

upload_destination = ""
port               = 0

def usage():
    print ("BHP Net Tool")
    print
    print ("USAGE: bhpnet.py -t target_host -p port")
    print ("-l --listen              - listen on [host]:[port] for incoming connections")

print ("bhpnet.py -t 192.168.0.1 -p 5555 -1 -c")
print ("bhpnet.py -t 192.168.0.1 -p 5555 -1 -u=c:\\target.exe")
print ("bhpnet.py -t 192.168.0.1 -p 5555 -1 -e=\"cat /etc/passwd\"")
print ("echo 'ABCDEFGHI' | ./bhpnet.py -t 192.168.11.12 -p 135")

尝试删除print语句之间的空格，如果您使用的是python 2.7旧版本，则不需要在print语句周围使用括号。也打印（“ BHP Net Tool”）打印在第二个语句中，为什么它为空，必须在下一行之间插入“ \ n”之类的内容。

 try:
    opts, args = getopt.getopt(sys.argv[1:],"hle:t:p:cu",      ["help","listen","execute","target","port","command","upload"])
except getopt.GetoptError as err:
    print str(err)
    usage()

在此代码段中，对于Python 2.6和更高版本以及Python 3.x：

except Exception as e: print(e)

对于Python 2.5及更早版本，请使用：

except Exception,e: print str(e)

所以您应该更改它。
