Re: python scripts with IIS

[Rolf van de Krol]

Adding the following lines before your print statement should do the 
trick. IIS complains about the headers, so adding headers should help.

print "Content-Type: text/html" # HTML is following
print   # blank line, end of headers

Re: stdin, stdout, redmon

[Rolf van de Krol]

According to various tutorials this should work.


|import sys
data = sys.stdin.readlines()
print "Counted", len(data), "lines."|


Please use google before asking such questions. This was found with only 
one search for the terms 'python read stdin'

Re: stdin, stdout, redmon

[Rolf van de Krol]

I don't know what you did with your Python installation, but for me this 
works perfectly.

test3.py contains:

import sys

print sys.stdin.readlines()


test.txt contains:

Testline1
Testline2


Output of 'python test3.py < test.txt' is:

['Testline1\n', 'Testline2']


Just plain simple and just works.

Re: stdin, stdout, redmon

[Rolf van de Krol]

Well, that's at least weird. I did test my code with Python 2.5 on Win 
XP, using the command prompt. But testing it with IDLE gives exactly the 
same error Bernard has. So apparently STDIN can't be accessed with IDLE.

Re: Executing other python code

[Rolf van de Krol]

AFAIK this can't be done with just python. You can use the C API of 
Python to achieve this. I don't know the details of that, but I guess 
you will need this (http://docs.python.org/api/api.html).

Re: [2.4.2/Linux] Getting Python to fork?

[Rolf van de Krol]

To create a deamon, you indeed need to fork two times. For more 
information and a working example see: 
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/278731 . I'm 
quite sure this works, because I used it several times to create a deamon.

Google is your friend. For example this:

It seems like that guy found the way to go for your problem.

You are right. You can't read STDIN from IDLE. There has been a topic 
about that before:

Hmm, 'of course' is not the correct word for it. Although the Stef 
Mientki would probably be able to find it in the documentation it is not 
as simple as you might think.
Most languages interpret a == b == 2 as (a == b) == 2, or throw an error 
because this syntax is not valid. The fact that python understand the 
obvious meaning of this code, is quite unique to Python, as far as I know.
