How to do an iteration?

Question

Python

Another question:
How can I iterate here?

def group_members():
    group = vk.groups.getMembers(group_id=164445012, fields=['first_name, last_name, online'])
    name = group['items'][0]['first_name']
    lname = group['items'][0]['last_name']
    online = group['items'][0]['online']
    iduser = group['items'][0]['id']
    if online == 0:
        online = 'Не в сети'
    else:
        online = 'В сети'
    print('|', name, lname, '|', 'id' + str(iduser), '|',  '==>', online)

I tried to do something with the increase, but I only got 2 users and that's it.
VC response:
{'count': 18, 'items': [{'id': xxxxx, 'first_name': lol', 'last_name': 'loles', 'online': 0}, {'id': xxxxx , 'first_name': 'loles, 'last_name': 'lol', 'online': 0}...
