[Tutor] Search text file, perform action if a given item found in file

[Eric]

I'm still new to this so please bare with me. I have spent a few hours 
searching google, and trying different combinations
and can't seem to figure out how to use endswith() to search a list, and 
to then take a action. In my case I would want to search through 
"l.split()[1:2]" for
the port number, and from there depending on if it finds a match it 
would go through a if-else statement, and then loop back
to he start to continue monitoring. I think I can handle the second 
part, but searching a list, and taking a action based on that search is 
somehting
that I am having a hard time grasping. Any help would be greatly greatly 
appreciated.



This is the output of print l.split()[1:2]

[]
['Connections']

['Local']
['0.0.0.0:135']
['0.0.0.0:445']
