Retrieve AWS secrets using boto3

I want to retrieve AWS secrets using python boto3 and I came across this sample code:

• aws-doc-sdk-examples/python/example_code/secretsmanager/get_secret_value.py at main · awsdocs/aws-doc-sdk-examples · GitHub
• Secrets Manager examples using SDK for Python (Boto3) - AWS SDK Code Examples

But it is confusing. I don't see boto3 library import in the python file. Not an expert of Python, so any help in understanding this much appreciated.

I was expecting to have the AWS secrets name and boto3 library as part of the python function.

Per the documentation, each of the example folders has one or more main runner scripts.

For the Secrets Manager examples, you would run either:

1. python scenario_get_secret.py, or
2. python scenario_get_batch_secrets.py

Each of these 'runner' scripts imports the relevant Python code e.g. get_secret_value.py.

The code is structured this way so that you can easily test the code while separating the test code from the reusable utility code (that you would potentially use).
