No, it doesn't. "a.read()" *returns* the contents, but you don't assign 
it, so it is discarded.

The idiomatic way would be iterating over the file-object itself - which 
will get you the lines:

with open("foo.txt") as inf:
     for line in inf:
         print line


The advantage is that this works even for large files that otherwise 
won't fit into memory. Your approach of reading the full contents can be 
used like this:

content = a.read()
for line in content.split("\n"):
     print line
