Cloudflare API - add origin to load balancer pool -- 2

I'd like to supply you with a list of IPs. As per the API doc [login to view URL] I'd like you to create/update an existing load balancer pool. The IPs will be the complete set of IPs for the pool (i.e. any prior IPs in the pool can be deleted). Note you will need to test with your own Cloudflare account before we accept any delivery. Please provide us a screencast. Please provide a BASh or Python script.
