I'm always disappointed when I find something that Python doesn't
handle in a platform independent way. It seems to me that file
locking is in that boat.
1. I don't see a way to atomically open a file for writing if and only
if it doesn't exist without resorting to os.open and specialized
platfor
What's more amazing is that anyone would click on the link at all given
the increasing number of website that provide hidden content that tries
to deliver spyware or viruses just by getting visitors.

Technically, I would call it a manfesto. The manifesto module is
probably the most facinating module in Python since it's the only one
whose functions consist entirely of doc strings followed by a pass and
do no useful work.

Of course it should thrown an exception because it was unable to do

I'm trying to build Python 2.4.1 on HP-UX 11.00 with full tcl/tk IDLE
support. So far, I haven't had any luck. I always wind up getting
errors of the form:

Currently I'm writing chucnks like:

Well, I finally managed to solve it myself by looking at some code.
The solution in Python is a little non-intuitive but this is how to get
it:
while 1:
line = stdout.readline()
if not line:
break
print 'LINE:', line,
If anyone can do it the more Pythonic way with some sort of
So here it is: handle unbuffered output from a child process.
Here is the child process script (bufcallee.py):
import time
print 'START'
time.sleep(10)
print 'STOP'
In Perl, I do:
open(FILE, "python bufcallee.py |");
while ($line = )
{
Unfortunatley that doesn't help. Even when callee is started using the
-u, I get the same behavior.

I am using the subprocess module in 2.4. Here's the fragment:
bufcaller.py:
import sys, subprocess
proc = subprocess.Popen('python bufcallee.py', bufsize=0, shell=True,
stdout=subprocess.PIPE)
for line in proc.stdout:
sys.stdout.write(line)
bufcallee.py:
12 matches
