1. Python obyekti "switches" YAML formatida yozing 2. "switches" ni o'zgartiring, shunda faqat "cisco" switchlar qoladi 3. standardise_macaddr buyrug'ida, "172.16.0.0/28" tarmog'ida oxirgi host manzilini oling 4. "dhcp_snooping_table" ni quyidagi formatdagi lug'atlar ro'yxatiga tahlil qiling: ```python dhcp_snooping_table_parsed = [ { "mac": "00:E9:BC:3F:A6:50", "ip": "100.1.1.6", "interface": "FastEthernet0/20", }, { "mac": "00:E9:22:11:A6:50", "ip": "100.1.1.7", "interface": "FastEthernet0/21", } ] ``` 5. "NetworkSubnet" nomli sinf yozing, uning 2 metodi bo'lsin: - get_subnet - belgilangan uzunlikdagi birinchi mavjud subnetni IPv4Network sinfi obyekti sifatida qaytaradi - show_network_pool - mavjud subnetlar ro'yxatini qaytaradi

172.16.0.0/28 tarmog'ida oxirgi host manzilini olish

import ipaddress

dhcp_snooping_table jadvalini lug'atlar ro'yxatiga tahlil qilish

dhcp_snooping_table = '''

qatorlar = dhcp_snooping_table.strip().split('\n')
dhcp_snooping_table_parsed = []
har qator uchun:
