Use case
I am trying to write a script for doing security group based on user’s input. the IpRanges is a list of dictionary. I intend to do a method which generate multiple dictionaries with the same key but different values, and put these dictionaries into a list.
ipaddress.ip_network method can evaluate both host ip address and ip subnet, if the value is not a valid subnet or ipv4 address an exception will be thrown, the collection will be based on only valid subnet or host ip address.
from ipaddress import ip_network
results = []
process_results = []
stop = int(input("how many source ip address you want"))
print("Press enter with empty response to quit.")
for i in range(0,stop):
ip = input("Source address:")
if ip is not "":
try:
ip_network(ip)
results.append(ip)
except ValueError as e:
print(e)
else:
break
# collecting the dictionary / dictionaries in a list
for result in results:
results_dict = {'ip': result}
process_results.append(results_dict)
print(process_results)
Test case 1: mixture of ip address and subnets
Test case 2: mixture of ip address, subnet and empty input
Test case 3: mixture of ip address, invalid data and subnet
