python - 值错误 : No closing quotation

Question

我有以下返回公共(public) IP 的代码

def gather_public_ip():
    ACCESS_KEY = config.get('aws','access_key')
    SECRET_KEY = config.get('aws','secret_key')
    regions = regions = ['us-west-2','eu-central-1','ap-southeast-1']
#    regions = config.get('aws','region').split(',')
    all_EIP = []
    for region in regions:
       client = boto3.client('ec2',aws_access_key_id=ACCESS_KEY,aws_secret_access_key=SECRET_KEY,region_name=region,)
       addresses_dict = client.describe_addresses()
       for eip_dict in addresses_dict['Addresses']:
         if 'PrivateIpAddress' in eip_dict:
            print eip_dict['PublicIp']
#       return str(eip_dict['PublicIp'])
            all_EIP.append(eip_dict['PublicIp'])
       print all_EIP
#           print str(all_EIP)
       return str(all_EIP)

这被调用并返回为:

   net_range = gather_public_ip()
   for ip in net_range:
          r = s.run(ip)

运行看起来像:

def run(self, targets="" ,options="-Pn"):
    #start a new nmap scan on localhost with some specific options

    syslog.syslog("Scan started")
    parsed = None
    nmproc = NmapProcess(targets,options)
    rc = nmproc.run()

    if rc != 0:
        syslog.syslog("nmap scan failed: {0}".format(nmproc.stderr))
    try:
        parsed = NmapParser.parse(nmproc.stdout)
        self.report = parsed
    except NmapParserException as e:
        syslog.syslog("Exception raised while parsing scan: {0}".format(e.msg))

    syslog.syslog("Scan complete")
    syslog.syslog("Scan duration: "+ str(parsed.elapsed))
    self.report = parsed
    return parsed

打印列表后，这让我:

Traceback (most recent call last):

    raw = self.read_token()

    raise ValueError, "No closing quotation"
ValueError: No closing quotation

Answer 1

确保您的 ip 不是 "" 否则 shlex 将失败，cf Which exception to raise if a given string does not match some format?
