python script to get wildcard mask output in the following format

[techrichit]

I am trying to convert wildcard mask to subnet mask. my input text file will be like this 192.168.0.1 0.0.0.255 My expected output : 192.168.0.1 0.255.255.255

I wrote code to convert wildnet mask to netmask. ex: my input file will have

Output:
0.0.0.15 
0.0.15.0
0.0.0.3

my outut will be :

Output:
255.255.255.240 
255.255.240.255 
255.255.255.252

The difficult part for me is to integrate the first half (i.e) 192.168.0.1 255.255.255.240

Can someone help me with the coding stuff to acheive this one.

Thanks in advance.

My code for second half:

import sys
f = open('test.txt','r')
for mask in f.readlines():
def wildcard_conversion(mask):
wildcard = []
for x in mask.split('.'):
component = 255 - int(x)
wildcard.append(str(component))
wildcard = '.'.join(wildcard)
return wildcard
wildcard = wildcard_conversion(mask)

ospf = (wildcard)
print(ospf)
f.close()

#end of program
