Delete kubernetes namespaces which are not deleting due to finalizers

run.py

import requests
import json

namespaces_response = requests.get('http://127.0.0.1:8001/api/v1/namespaces').json()

for namespace_item in namespaces_response['items']:
    if namespace_item['status']['phase'] == 'Terminating':

        url = 'http://127.0.0.1:8001/api/v1/namespaces/%s' % namespace_item['metadata']['name']
        namespace_get_data = requests.get(url).json()

        updated_body = namespace_get_data
        updated_body['spec'] = {}
        updated_body['metadata']['finalizers'] = []

        print(updated_body)

        requests.put(url + '/finalize', json=updated_body)

        requests.delete(url)

        response = requests.get(url)
        print (response)

You need requests:
pip install requests

You also need to connect to your kubernetes cluster with:
kubectl proxy

Run this script to remove all finalizers on hung namespaces
