Learn what IAM policies are necessary to retrieve objects from S3 buckets. You can do more than list, too. Here’s the complete code sample, which uses Boto3: @ contextmanager def S3Client (): S3_ACCESS_KEY = os. import boto3 s3 = boto3. s3 = boto3.client ('s3') Notice, that in many cases and in many examples you can see the boto3.resource instead of boto3.client. For example: import boto3 some_binary_data = b'Here we have some data' more_binary_data = b'Here we have some more data' # Method 1: Object.put() s3 = boto3.resource('s3') object = s3.Object('my_bucket_name', 'my/key/including/filename.txt') object.put(Body=some_binary_data) # Method 2: Client.put_object() client = boto3.client('s3') … These examples are extracted from open source projects.
