我已经编写了一个代码来使用对流层创建 CloudFormation 模板，我在其中创建 EC2 实例并分配 SG 和 EIP，但在运行 python 代码时出错。代码如下：

from troposphere import Ref, Template, join, GetAtt, Parameter
import troposphere.ec2 as ec2

template = Template()

#Creating Security Group

SSHSecurityGroup = ec2.SecurityGroup('SSHSecurityGroup')
SSHSecurityGroup.GroupDescription = "Enable SSH access bia port 22"
SSHSecurityGroup.SecurityGroupIngress = [
    ec2.SecurityGroupRule(
        CidrIP="0.0.0.0/0",
        FromPort="22",
        IpProtocol="tcp",
        ToPort="22",
        )]

ServerSecurityGroup = ec2.SecurityGroup('ServerSecurityGroup')
ServerSecurityGroup.GroupDescription("Allow access from specified CIDR range")
ServerSecurityGroup.SecurityGroupIngress = [
    ec2.SecurityGroupRule(
        IpProtocol="tcp",
        FromPort="80",
        ToPort="80",
        CidrIp="0.0.0.0/0",
        IpProtocol="tcp",
        FromPort="22",
        ToPort="22",
        CidrIP="192.168.1.1/32",
    )]
template.add_resource(SSHSecurityGroup)
template.add_resource(ServerSecurityGroup)
#Creating EC2 Instance
ec2_instance = template.add_resource(ec2.Instance("MyEC2Intsance",
    ImageId="ami-i23df45832",
    AvailabilityZone="us-east-2",
    InstanceType="t2.micro",
    EIP=Ref(MyEIP),
    SecurityGroups=[Ref(SSHSecurityGroup),Ref(ServerSecurityGroup)],
    ))

#Creating EIP
MyEIP = ec2.EIP("MyEIP", InstanceId=Ref(MyEC2Intsance)
#template.add_resource(MyEIP)
print(template.to_yaml())```

此行需要一个尾随（关闭）括号：更改此：

MyEIP = ec2.EIP("MyEIP", InstanceId=Ref(MyEC2Intsance)

对此：

MyEIP = ec2.EIP("MyEIP", InstanceId=Ref(MyEC2Intsance))

SecurityGroupIngress/SecurityGroupRules 还有其他问题，但不知道如何指导，因为不确定您在尝试什么。
