How to pull deeply nested data from a dictionary in ansible - ansible

Question

I am trying to print nested data from an ansible dictionary. However, I cannot figure out how to pull the nested values. Specifically, in the data below, I am trying to print the two values returned under "ipv4". Currently, the output of item.value.ipv4 is the portion in brackets below:
"msg": "GigabitEthernet0/0/0,[{'address': '192.168.3.1', 'subnet': '28'}]"
I would like to just use the value like so:
"msg": "GigabitEthernet0/0/0, 192.168.3.1, 28"
I cannot figure out how to pull this nested data out of to do this. To put it simply, it would be nice if something like this worked: item.value.ipv4['address']. How is this done?
tasks:
- name: get config for Cisco IOS
ios_facts:
gather_subset: all
gather_network_resources: interfaces
- name: create dictionary with ansible_net_interfaces
set_fact:
foo_value: "{{ query('dict', ansible_net_interfaces) }}"
- name: display the results of foo_value
debug:
msg: "{{ foo_value }}"
- name: display certain detalys values from foo_value
debug:
msg: "{{ item.key }},{{ item.value.ipv4 }}"
with_items: "{{ foo_value }}"
These tasks produce the following:
TASK [display the results of foo] **********************************************************************************************************************
ok: [192.168.3.1] => {
"msg": [

"key": "GigabitEthernet0/0/0",

"description": "This is an interface description",
"duplex": "Full",

{
"address": "192.168.3.1",
"subnet": "28"
}

},

ipv4 is a list of dictionaries. Assuming you need only the first dictionary,
- name: display certain detalys values from foo_value
debug:
msg: "{{ item.key }},{{ item.value.ipv4[0].address }},{{ item.value.ipv4[0].subnet }}"
when: item.value.ipv4 is defined and item.value.ipv4[0].subnet is defined and item.value.ipv4[0].address is defined
with_items: "{{ foo_value }}"
