Yes. `.read()` [with no argument] on a file-like object reads until
EOF. See http://docs.python.org/library/stdtypes.html#file.read

Is this the expected behaviour?
When I run this script, it reads only once, but I expected once per line with
bufsize=1.
What I am trying to do is display the output of a slow process in a tkinter
window as it runs. Right now, the process runs to completion, then display the
result.

Use another language.
By design, Python does not provide pointers. This is a good thing,

The problem with that sort of idea is that it mucks up garbage
collection. CPython, for example

Not possible.
Hi people!
I have asked myself the following thing.
How do I access the address of an object and later get the object from
that address ?!
I am heavily interisted.
thank you

I just installed 2.7... should have done this a while ago. pip finally works!
Thanks!

No (with the exception of `True` and `False` being rebinable in Python
2). The idiomatic `while 1` no

Probably because of the fact it is possible to set True equal to False and
consequently then invalidate loop logic as presented below:
True = False
while True:
...
On the other hand `1' will always be evaluated as a constant.
Don't know, just guessing.

I want to run a server side python script when a button on a web page
is clicked. This is on a LAMP server - apache2 on xubuntu 11.10.
I know I *could* run it as a CGI script but I don't want to change the
web page at all when the button is clicked (I'll see the effect
elsewhere on the screen any

Actually there was the same question here (sorry should have looked before)
http://stackoverflow.com/questions/3815359/while-1-vs-for-whiletrue-why-is-there-a-difference
And I think the main reason is that 1 is a constant while True is not
such and can be reassigned.
