How can I use versioning in S3 with boto3?

Question

I am using a versioned S3 bucket, with boto3. How can I retrieve all versions for a given key (or even all versions for all keys) ? I can do this:

for os in b.objects.filter(Prefix=pref):
    print("os.key")
     

but that gives me only the most recent version for each key.

Answer 1

import boto3

bucket = 'bucket name'
key = 'key'
s3 = boto3.resource('s3')
versions = s3.Bucket(bucket).object_versions.filter(Prefix=key)

for version in versions:
    obj = version.get()
    print(obj.get('VersionId'), obj.get('ContentLength'), obj.get('LastModified'))

I can't take credit as I had the same question but I found this here
