Well,  yeah, but it won't go into the if statement if there isn't a 
match so what does that matter?

Did you try my example yet?
It should work just fine.
just iterate over both of the lists...
for item1 in List1:
    for item2 in List2:
       if item1 == item2: #this is equivalent to 'if item1 in List2' 
except will match ALL occurrences of item1 in List2.  if you want to 
only match the first, add a break.
          print item1+ ' ' + item2
