Not able to create boto ses client on AWS Lambda for sending mail

Question

my python code is not working on Lambda which actully works well when I run it from my local python environment. Whenever I try to create SES object on Lambda function, I get this error:

Response:
{
  "errorMessage": "Unable to import module 'lambda_function'"
}

Here's my code:

def lambda_handler(event, context):

    connection = boto.ses.connect_to_region('us-east-1')


    return connection.send_email(
            from_addr,
            subject,
            None,
            to,
            format= format,
            text_body=text,
            html_body=html
        )   

Is it something related to boto.ses not being supported over lambda and I have to use boto3 instead??

This lambda function contains multiple part and at the end I have to create SES object to send mail to my client, but when I try to do that I'm getting this error

These days, it is highly recommended to use boto3.

The syntax is:

import boto3

connection = boto3.client('ses', region_name='us-east-1')

response = client.send_email(
    Source='string',
    Destination={
        'ToAddresses': [
            'string',
        ],
        'CcAddresses': [
            'string',
        ],
        'BccAddresses': [
            'string',
        ]
    },
    Message={
        'Subject': {
            'Data': 'string',
            'Charset': 'string'
        },
        'Body': {
            'Text': {
                'Data': 'string',
                'Charset': 'string'
            },
            'Html': {
                'Data': 'string',
                'Charset': 'string'
            }
        }
    },
    ReplyToAddresses=[
        'string',
    ],
    ReturnPath='string',
    SourceArn='string',
    ReturnPathArn='string',
    Tags=[
        {
            'Name': 'string',
            'Value': 'string'
        },
    ],
    ConfigurationSetName='string'
)
