Because by using boto3 resource to get objects from S3, you can get satisfied result by using the returned file extension to filter what you want. Like this:

import boto3
s3 = boto3.resource('s3')
my_bucket = s3.Bucket('my_bucket')
files = my_bucket.objects.all()
file_list = []
for file in files:
    if file.key.endswith('.docx'):
         file_list.append(file.key)

You can change the endswith string with what you want.
