Before you run this script:

1. Install Boto3 using pip if you haven't already: pip install boto3.

2. Configure your AWS credentials properly. You can either set them up using the AWS CLI (aws configure) or set environment variables (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY).

3. Ensure that the IAM user associated with your credentials has the necessary permissions to delete S3 buckets and objects. Be cautious about granting such permissions.

Make sure check your I AM console does user contains privileges to delete the Resources. In My case I have provide Admin Privileges to my user.

Also, I have added this code in case you are unable to delete a bucket due to certain reasons.

Code Reference:

import boto3
import botocore

def empty_bucket(s3_client, bucket_name):
    # List all objects including versions
    response = s3_client.list_object_versions(Bucket=bucket_name)

    # Delete all objects including versions
    if 'Versions' in response:
        for obj in response['Versions']:
            s3_client.delete_object(Bucket=bucket_name, Key=obj['Key'], VersionId=obj['VersionId'])
            print(f"Deleted versioned object: {obj['Key']}")

    # Delete all delete markers
    if 'DeleteMarkers' in response:
        for marker in response['DeleteMarkers']:
            s3_client.delete_object(Bucket=bucket_name, Key=marker['Key'], VersionId=marker['VersionId'])
            print(f"Deleted delete marker: {marker['Key']}")

    # Empty the bucket
    response = s3_client.list_objects_v2(Bucket=bucket_name)
    if 'Contents' in response:
        for obj in response['Contents']:
            s3_client.delete_object(Bucket=bucket_name, Key=obj['Key'])
            print(f"Deleted object: {obj['Key']}")

def delete_all_buckets():
    # Create an S3 client
    s3 = boto3.client('s3')

    # List all buckets
    response = s3.list_buckets()

    # Iterate over each bucket, empty it, then delete it
    for bucket in response['Buckets']:
        bucket_name = bucket['Name']
        print(f"Emptying bucket {bucket_name}...")

        # Empty the bucket
        try:
            empty_bucket(s3, bucket_name)
        except botocore.exceptions.ClientError as e:
            if e.response['Error']['Code'] == 'AccessDenied':
                print(f"Access denied. Skipping bucket deletion: {bucket_name}")
                continue
            else:
                raise

        print(f"Deleting bucket {bucket_name}...")
        # Delete the bucket
        try:
            s3.delete_bucket(Bucket=bucket_name)
            print(f"Deleted bucket: {bucket_name}")
        except botocore.exceptions.ClientError as e:
            if e.response['Error']['Code'] == 'AccessDenied':
                print(f"Access denied. Skipping bucket deletion: {bucket_name}")
            else:
                raise

if __name__ == "__main__":
    delete_all_buckets()
