Assuming file 'test.txt' exists, your program should work.
In your case, you can ommit the + in 'r+', or the 'r+' alltogether.
Also, choosing file as a variable is not a good idea, as it
hides the builtin function (which could have been used
as well instead of open()).

What your problem might be, is not seeing anything as
you do not fetch the result of fil.readlines().
So just do
lines = fil.readlines()
print lines
#or
for line in lines:
     print line
