[SOLVED] Access keys and values from nested dictionary?

[Winfried]

Hello,

I'm not used to what appears to be a nested dictionary in a list, and can't find how to get the keys and values:

for x in ifaddr.get_adapters():
	print(x)
	"""
	Adapter(name='{FC153F79-475E-430D-B95A-06E966794B49}', nice_name='Realtek PCIe GbE Family Controller', ips=[IP(ip=('2a01:e0a:590:fd80:1a08:50b2:881d:2947', 0, 0), network_prefix=64, nice_name='Ethernet'), IP(ip=('fe80::6b43:963:5027:aacd', 0, 20), network_prefix=64, nice_name='Ethernet'), IP(ip='192.168.0.16', network_prefix=24, nice_name='Ethernet')], index=20)
	"""
	
	#AttributeError: 'Adapter' object has no attribute 'items'
	for key, value in x.items() :
		print(key)

	#TypeError: 'Adapter' object is not iterable
	#for y in x:
	#AttributeError: 'Adapter' object has no attribute 'items'
	"""
	for y in x.items():
		print(y + ':', x[y])
	"""

	#TypeError: 'Adapter' object is not subscriptable
	#print(x[0])

I need to grab each adapter's nice_name. Does someone know?

Thank you.

Hi,

what type of object is "Adapter". Based on the error message, it is obviously not a dictionary. You can check the type of an object by type(objectname). If I have to take a guess, it is an instance of a class.

And which name_name are you looking for? It appear twice, once top level and once inside the ips list. The one or the other way: there are no nested dictionaries in the output you show...

As mention over you not dealing with dictionary
ifaddr.get_adapters() returns a list of Adapter objects,and each Adapter has attributes like .nice_name .ip.

for adapter in get_adapters():
    print(f"Adapter nice_name: {adapter.nice_name}")
    for ip in adapter.ips:
        # In real ifaddr, IPv6 is a tuple, IPv4 is a string, like in your example
        addr = ip.ip[0] if isinstance(ip.ip, tuple) else ip.ip
        print(f"  IP:{addr} / {ip.network_prefix}")

Output:
Adapter nice_name: Realtek PCIe GbE Family Controller
  IP:2a01:e0a:590:fd80:1a08:50b2:881d:2947 / 64
  IP:fe80::6b43:963:5027:aacd / 64
  IP:192.168.0.16 / 24
Adapter nice_name: Wi-Fi
  IP:10.0.0.5 / 24

All these are properties of object of class ifaddr.Adapter
You can access any of them using standard dot notation e.g. x.nice_name
Check the docs:
