How to create a new python dictionary from loop results without overwrite

I get stuck when I try to create a new dictionary with the result from each file.
Basically I have a bunch of files which I’m reading it using glob and json, so I managed to get the value from each file and it’s working fine, it’s displaying all files content with the different informations which is the expected and it’s good.

But now I’m looking about how to create a new dictionary new_dictonary = {} #in my code using the variable I’ve got get_hostname, get_fs_type, get_uptime without overwrite the new dictionary, below is my code.

import json
import glob
    
test_inventory = glob.glob('inventory/facts_am4/*')
new_dictonary = {}
for files in test_inventory:
    with open(files, 'r') as jsonfile:
        myfile = json.load(jsonfile)
        get_hostname = myfile['ansible_facts']['facter_networking']['fqdn']
        get_fs_type = myfile['ansible_facts']['facter_filesystems']
        get_uptime = myfile['ansible_facts']['facter_system_uptime']['uptime']
        print('Hostname: ' + get_hostname)
        print('FS Type:' + get_fs_type)
        print('Uptime:' + get_uptime)
        #Here I need something which you grab the variables and create a new dictionary.
        #Without overwrite.

I really tried a lot of stuffs, I’m learning Python and I came here to kindly request you help.
