But you do create that extra TextIOWrapper, so there should
be no crying about its existence.  If you rely on the data structure
of another object, it is a good idea to hold onto that object, rather
than simply hold onto a field or two of its class.

So, at the least, you need these changes:

But, I'd say the right was to write this last is:

    with file(open('p.py', 'rb')) as src:
        print(src.read())
