Nope - no more, should I say. The file object is now an iterable. 
file.readlines() try and read all the file and returns it as a list. 
It's ok for small files, but can lead to problem with huge ones... using 
the file as an iterator, you have a lazy read - just like you would with 
the older file.readline() idiom:

line = f.readline()
while line:
   do_something_with(line)
   line = f.readline()

but with much less hassle :

for line in f:
   do_something_with(line)
