Quick way to list all files in Amazon S3 bucket?

Question

I have an amazon s3 bucket that has tens of thousands of filenames in it. What\'s the easiest way to get a text file that lists all the filenames in the bucket?

I know its old topic, but I'd like to contribute too.

With the newer version of boto3 and python, you can get the files as follow:

import os
import boto3
from botocore.exceptions import ClientError    

client = boto3.client('s3')

bucket = client.list_objects(Bucket=BUCKET_NAME)
for content in bucket["Contents"]:
    key = content["key"]

Keep in mind that this solution not comprehends pagination.
