How to upload a file to S3 without creating a temporary local file

Question

Is there any feasible way to upload a file which is generated dynamically to amazon s3 directly without first create a local file and then upload to the s3 server? I use python.

Answer 1

Update for boto3:

aws_session = boto3.Session('my_access_key_id', 'my_secret_access_key')
s3 = aws_session.resource('s3')
s3.Bucket('my_bucket').put_object(Key='file_name.txt', Body=my_file)
