cdk.json - contains context variables which are required for our stack to run

"app": "python app.py", - runtime (python) and main application file

context variables used in all stacks

    "context":{
        "project_name": "serverless",
        "env": "dev"
    }

requirements.txt - contains all CDK modules that need to be installed using python pip

cdk ls
