how to delete files from amazon s3 bucket?

Question

Using boto3 (currently version 1.4.4) use S3.Object.delete().

import boto3

s3 = boto3.resource('s3')
s3.Object('your-bucket', 'your-key').delete()

Using the Python boto3 SDK (and assuming credentials are setup for AWS), the following will delete a specified object in a bucket:

import boto3

client = boto3.client('s3')
client.delete_object(Bucket='mybucketname', Key='myfile.whatever')

found one more way to do it using the boto:

from boto.s3.connection import S3Connection, Bucket, Key

conn = S3Connection(AWS_ACCESS_KEY, AWS_SECERET_KEY)

b = Bucket(conn, S3_BUCKET_NAME)

k = Key(b)

k.key = 'images/my-images/'+filename

b.delete_key(k)

Welcome to 2020 here is the answer in Python/Django:

from django.conf import settings 
import boto3   
s3 = boto3.client('s3')
s3.delete_object(Bucket=settings.AWS_STORAGE_BUCKET_NAME, Key=f"media/{item.file.name}")

Took me far too long to find the answer and it was as simple as this.

please try this code

import boto3   
s3 = boto3.client('s3')
s3.delete_object(Bucket="s3bucketname", Key="s3filepath")

Try to look for an updated method, since Boto3 might change from time to time. I used my_bucket.delete_objects():

import boto3
from boto3.session import Session

session = Session(aws_access_key_id='your_key_id',
                  aws_secret_access_key='your_secret_key')

# s3_client = session.client('s3')
s3_resource = session.resource('s3')
my_bucket = s3_resource.Bucket("your_bucket_name")

response = my_bucket.delete_objects(
    Delete={
        'Objects': [
            {
                'Key': "your_file_name_key"   # the_name of_your_file
            }
        ]
    }
)
