How to upload a file to S3 and make it public using boto3? : <p>I am able to upload an image file using:</p>

<pre><code>s3 = session.resource('s3')
bucket = s3.Bucket(S3_BUCKET)
bucket.upload_file(file, key)
</code></pre>

<p>However, I want to make the file public too. I tried looking up for some functions to set ACL for the file but seems like boto3 have changes their API and removed some functions. Is there a way to do it in the latest release of boto3?</p>
