I think so, but only because readlines is a builtin function.
If it wasn't, there would be a stack frame for readlines, which
would have "self" as a local variable.

Yes. The file object only lives on the evaluation stack,

In CPython, fp gets closed when it leaves scope. In other
implementations you may need try
def uselessHash(filename):
fp= open(filename)
hash= 0
for line in fp:
hash ^= hash(line.strip())
fp.close() # do I need this or is fp closed by ref count?
return hash
Consider the function above. Do I need the fp.close(), or will the
file be closed automatically when fp goes out
