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?

Answer 1

For Python's boto3 after having used aws configure:

import boto3
s3 = boto3.resource('s3')

bucket = s3.Bucket('name')
for obj in bucket.objects.all():
    print(obj.key)
