problem with read() write()

[Zeynel]

Hello,

I've been studying the official tutorial, so far it's been fun, but
today I ran into a problem with the write(). So, I open the file pw
and write "hello" and read:

f = open("pw", "r+")
f.write("hello")
f.read()

But read() returns a bunch of what looks like meta code:

"ont': 1, 'center_insert_even\xc4\x00K\x02\xe8\xe1[\x02z\x8e
\xa5\x02\x0b
\x00\x00\x00\x00\x00\x00\x00\x08\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'QUEUE'\np1\n
(S'exec' ....

What am I doing wrong? Thank you.
