How to list Cisco device interface status using Python, TEXTFSM, NETMIKO and list comprehension logic

from netmiko import ConnectHandler
from operator import itemgetter

RTR_10 = {
'ip': '10.10.10.10',
'username': 'admin',
'password': 'admin',
'device_type': 'cisco_ios',
}
print ('Checking interface status..')
net_connect = ConnectHandler(**RTR_10)

output = net_connect.send_command('show ip int brie', use_textfsm=True)
devlist = []
for i in output:
if i['status'] == 'up':
devlist.append(i['intf'])
print(devlist)

print([i for i in output if i['status'] == 'up'])
print ([i['intf'] for i in output if i['status'] == 'up'])

print('\n \n')

print ('\nList of interfaces which are UP \n')
statusup =[i['intf'] for i in output if i['status'] == 'up']

for ifaceup in statusup:
print (ifaceup)

print ('\nList of interfaces which are DOWN \n')
statusother =[i for i in output if i['status'] != 'up']
for ifaceother in statusother:
print (ifaceother['intf'] + ' ' + ifacesother['status'] )
