How to sort a json Dict by the value of a key

For example a list of domains:

domains = [
    {'mkey': 'apple.co.za', 'is_association': True},
    {'mkey': 'banana.org', 'is_association': True},
    {'mkey': 'beans.com', 'is_association': True},
    {'mkey': 'zulu.co.za', 'is_association': True},
    {'mkey': 'maakebos.com', 'is_association': True},
    {'mkey': 'thule.co.za', 'is_association': True},
    {'mkey': 'pollock.com', 'is_association': True},
    {'mkey': 'queen.co.za', 'is_association': True},
    {'mkey': 'zebra.co.uk', 'is_association': True},
]

To sort the items by the mkey:

sorted_domains_atoz = sorted( 
    domains, 
    key = lambda i: i['mkey'] 
)

[{'mkey': 'apple.co.za', 'is_association': True},
{'mkey': 'banana.org', 'is_association': True},
{'mkey': 'beans.com', 'is_association': True},
{'mkey': 'maakebos.com', 'is_association': True},
{'mkey': 'pollock.com', 'is_association': True},
{'mkey': 'queen.co.za', 'is_association': True},
{'mkey': 'thule.co.za', 'is_association': True},
{'mkey': 'zebra.co.uk', 'is_association': True},
{'mkey': 'zulu.co.za', 'is_association': True}]

To sort the reverse order, use the reverse=True keyword argument

sorted_domains_ztoa = sorted( 
    domains, 
    key = lambda i: i['mkey'], 
    reverse=True 
)

[{'mkey': 'zulu.co.za', 'is_association': True},
{'mkey': 'zebra.co.uk', 'is_association': True},
{'mkey': 'thule.co.za', 'is_association': True},
{'mkey': 'queen.co.za', 'is_association': True},
{'mkey': 'pollock.com', 'is_association': True},
{'mkey': 'maakebos.com', 'is_association': True},
{'mkey': 'beans.com', 'is_association': True},
{'mkey': 'banana.org', 'is_association': True},
{'mkey': 'apple.co.za', 'is_association': True}]
