I'm aware that with Boto 2 it's possible to open an S3 object as a string with: get_contents_as_string()
Is there an equivalent function in boto3 ?
read
will return bytes. At least for Python 3, if you want to return a string, you have to decode using the right encoding:
import boto3
s3 = boto3.resource('s3')
obj = s3.Object(bucket, key)
obj.get()['Body'].read().decode('utf-8')
