# create a test folder as below, or name it whatever you want.
$ mkdir cdk-test
$ cd cdk-test
# create the aws cdk project by init sub-command and sample application, specify the language as python
$ cdk init sample-app --language=python

Activate the python environment, and install all of the required libs by pip.

$ python3 -m venv .env
$ source .env/bin/activate
