Your issue related to decoding the object return from s3.You need to read the file as csv.

Take a look at the following code snippet:

    import boto3
    import csv

    s3 = boto3.client('s3')

    def lambda_handler(event, context):
        obj = s3.get_object(Bucket='Bucket_Name', Key='File_Name.csv')
        data = obj['Body'].read().decode('utf-8').splitlines()
        lines = csv.reader(data)
        headers = next(lines)
        print('headers: %s' %(headers))
        for line in lines:
            print(line)

Output :

Dummy csv.
