如何从输出中去掉unicode'u'？Python

Question

下面的代码在sec组中查找0.0.0.0/0，并在slack时打印。在

def getTag(connection, instanceId):
    reservations=connection.get_all_instances(filters={'instance_id':instanceId})
    for res in reservations:
      for instance in res.instances:
        if instance.state == "running":
           return instance.tags['Name'],instance.private_ip_address,instance.region
        else:
           return None

#regions = ['us-east-1','us-west-1','us-west-2','eu-west-1','sa-east-1','ap-southeast-1','ap-southeast-2','ap-northeast-1']
#regions = ['us-west-2','eu-central-1','ap-southeast-1']  ##Prod VPC
regions = ['us-west-2']
data = []
header = ["Port","Open For","Security group","Instance Details"]

for region in regions:
    connection=ec2.connect_to_region(region)
    sg = connection.get_all_security_groups()
    try:
        for securityGroup in sg:
           for rule in securityGroup.rules:
               if '0.0.0.0/0' in str(rule.grants):
                  for instanceid in securityGroup.instances():
                      instanceId=str(instanceid)
                     # print instanceId
                      tag = getTag(connection, instanceId.split(':')[1])
                      if tag is not None:
                        # print tab              
                         tab =[str(rule.to_port),"0.0.0.0/0",str(securityGroup.name),str(getTag(connection, instanceId.split(':')[1]))]
                         data.append(tab)
    except Exception,e:
        pass

print tabulate(data, headers=header, tablefmt='simple')
cool_stuff = tabulate(data, headers=header, tablefmt='simple')
slack.chat.post_message('#scanbot','```'+cool_stuff+'```',username='AWS_security_group_scanner')

问题是，这会打印：

^{pr2}$

我想除掉“u”，因为他们在捣乱那些松懈的东西。有人能帮我吗？在

希望这个有用

import unicodedata
for region in regions:
    connection=ec2.connect_to_region(region)
    sg = connection.get_all_security_groups()
    try:
        for securityGroup in sg:
           for rule in securityGroup.rules:
               if '0.0.0.0/0' in str(rule.grants):
                  for instanceid in securityGroup.instances():
                      instanceId=str(instanceid)
                     # print instanceId
                      tag = getTag(connection, instanceId.split(':')[1])
                      if tag is not None:

                         data.append(tab)
