urlopen.read()

[ken]

Hi,

When I call urlopen.read() like this:

data = urlopen("http://localhost").read().

Does that mean I will read the whole document to data, regardless how
many data being sent back?

Thank you.

Yes. However you can read (and presumably process)one line at a time
with readline() or by iterating over the object returned by urlopen().

I'd recommend trying something like:

u = urlopen("http://localghost/")
for line in u:
print line # or process it some other way

or

line = u.readline()
while line:
# process the line
line = u.readline()

There is no need to buffer the whole content before you process it
unless you choose to do so.
