Lambda function to delete an S3 bucket using Boto

I am working on a Boto script to delete the resource when invoked by a lambda function, I am not sure how to invoke the delete function using Lambda, "path" has the resource to be deleted and below is the lambda function being used to delete the resource . Thanks in advance.

print(path)
def delete_bucket(path):  
    while True:
        objects = s3.list_objects(Bucket=path)
        content = objects.get('Contents', [])
        if len(content) == 0:
            break
        for obj in content:
            s3.delete_object(Bucket=path, Key=obj['Key'])
    s3.delete_bucket(Bucket=path)
    
def lambda_handler(event, context):

    delete_bucket(path)

Following code is verified on Python 3.8;

import boto3


def get_s3_client():
    return boto3.client('s3', region_name='eu-west-1') #change region_name as per your setup

def delete_bucket(bucket_name): #here bucket_name can be path as per logic in your code 
    s3_client = get_s3_client()
    while True:
        objects = s3_client.list_objects(Bucket=bucket_name)
        content = objects.get('Contents', [])
        if len(content) == 0:
            break
        for obj in content:
            s3_client.delete_object(Bucket=bucket_name, Key=obj['Key'])
    s3_client.delete_bucket(Bucket=bucket_name)
    
def lambda_handler(event, context):
    # put your existing logic here
    delete_bucket(path)

Note: If you have versioning enabled for the bucket, then you will need extra logic to list objects using list_object_versions and then iterate over such a version object to delete them using delete_object
