How to add boto library to an python-based AWS lambda function?

Question

I want to create a lambda function in python3.7 that it will use boto to perform some AWS query.

The function is very simple. I added import boto to the simple vanilla template to try out how to enable boto.

import json

import boto

def lambda_handler(event, context):
    # TODO implement
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }

Needless to say, it fails:

Response:
{
  "errorMessage": "Unable to import module 'lambda_function': No module named 'boto'",
  "errorType": "Runtime.ImportModuleError"
}

So how can I add boto to my code?

I have checked out Layers and it is empty.

I think I can create on by uploading a zip file. But what should I put inside the zip file? What sort of directory structure is Lambda expecting?

boto has been deprecated. You should be using boto3.

Import boto3

This is like adding additional dependencies to aws lambda.

Please follow document to add boto package.
