This should print every line in the file, adding .com at the end:

wordList = "/tmp/Wordlist"
with open(wordList, 'r') as wl:
   for line in wl:
     print line.rstrip() + '.com '

Note that:
- I iterate over the file self; files are their own line-iterators.
- I've used the 'r' mode instead (I assume it's a text file because you  
read it line by line, and as you don't update it, the '+' isn't required)
- the line read includes the end-of-line '\n' at the end; rstrip() removes  
it and any trailing whitespace. If you don't want this, use rstrip('\n')
- I've used the with statement to ensure the file is closed at the end
