import boto3

cloudformation = boto3.resource('cloudformation')
stack = cloudformation.Stack('StackName')
print(stack.stack_status)

Since what you get as a response is a list of dictionaries, you can access the stack status with the following line:

stack_status = stack['Stacks'][0]['StackStatus']
print(stack_status)

It should ouput:

CREATE_COMPLETE
