I can't figure out how to update a contact

[pdath]

I'm trying to update a phone number in a contact (actually lots and lots of contacts). I start out going:

paginated_contacts = manage_api_client.company.contacts.paginated(1,00)
for contact in paginated_contacts.all():
...
contact.default_phone_nbr="xxx"

How do I post that update?
manage_api_client.company.contacts.post(contact)
contact.post()
I can't seem to guess the syntax.

For anyone finding this in the future I finally figured it out. Basically to update a field (like phone number) you do something like:

paginated_contacts = manage_api_client.company.contacts.paginated(1,00)
for contact in paginated_contacts.all():
# Skip records with no contact info at all
if(contact.communication_items) is None:
continue;

for communication in contact.communication_items:
	# Only process contact phone numbers
	if(not(communication.type.name=="Direct" or communication.type.name=="Mobile" or communication.type.name=="Home")):
		continue;

	payload = [{"op": "replace", "path": "value", "value": "+1(813)0005555"}]
	manage_api_client.company.contacts.id(contact.id).communications.id(communication.id).patch(payload)
