Stack.account returns <property object at 0x0...> instead of a string. Python

I am using a construct in my stack to create an EC2 instance. Inside the construct, I want to verify that the account number is valid before continuing. However, I am struggling to get the account number to test against. Any time I reference Stack.account whether printing it or setting it to a variable I get <property object at 0x0...> instead of an account number as a string. I am using CDK V2 and according to the CDK API Stack.account should return a string of the account the stack will be deployed to, but it is not. Is there a way I can get the account value returned as a string? Thanks.

Each section of code below comes from different files within my project.

Code that calls Stack Creation:

from temp_stack import TempStack

app = App()

windows_stack = TempStack(app,
    "temp_stack",
    stack_params = parameters,
    env = {
        'account': parameters['account'],
        'region': 'us-east-1'
    }
)

Stack Creation:

from constructs import Construct
from construct_library import Instance

class TempStack(Stack):

    def __init__(self, scope: Construct, construct_id: str, stack_params: dict, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        hosts = stack_params['hosts']

                        #Instance is the construct creating the EC2
        test_instance = Instance(self, host['hostname'], host, instance_sg=sec_group).instance

Within the Instance Construct:

from constructs import Construct
from aws_cdk import Stack

class Instance(Construct) :

print(Stack.account)
#Output is: <property object at 0x0...>

test = Stack.account
print(test) 
#Output: <property object at 0x0...>
