[FIXED] Get only file names from s3 bucket folder

Issue

I have a s3 bucket named 'Sample_Bucket' in which there is a folder called 'Sample_Folder'. I need to get only the names of all the files in the folder 'Sample_Folder'.

I am using the following code to do so -

import boto3
s3 = boto3.resource('s3', region_name='us-east-1', verify=False)
    bucket = s3.Bucket('Sample_Bucket')
    for files in bucket.objects.filter(Prefix='Sample_Folder):
        print(files)

The variable files contain object variables which has the filename as key.

s3.ObjectSummary(bucket_name='Sample-Bucket', key='Sample_Folder/Sample_File.txt')

But I need only the filename. How do I extract that? Or is there any other way to do it?

Solution

You should use list_object_v2 which gives you the list from the defined prefix used.

... snippet ...

filenames = []

get_filenames(s3):
    result = s3.list_objects_v2(Bucket=bucket, Prefix=prefix)
    for item in result['Contents']:
        files = item['Key']
        print(files)
        filenames.append(files)   #optional if you have more filefolders to got through.
    return filenames

get_filenames(my_bucketfolder)
