Hi tutors,
I've got an external program that I'm calling from python with
os.popen. The problem is that I need to pass this program an arbitrary
body of text. I've tried escaping characters before passing it as
input but the shell still expands out certain characters. I noticed
with python2.4. How
Say I have a directory tree like this:
foo
- bar
-- quux.py
- baz
-- glonk.py
>From within glonk.py, how do I import quux.py? I've tried going to
foo, running baz/glonk.py, and using "from bar import quux", but this
doesn't seem to work.
Thanks in advance!

The first thing I'd do is create the command string before passing
it to popen - that way we can debug easier by seeing exactly what

As a newbie developer, the easiest way for me to connect to MySQL is to

This a very simple connection using mysql.
1. connect to mysql:
db = mySQLdb.connect(user='root',passwd='something')
2. To execute and get the result:
c = db.cursor()
c.execute(sql comment)
result = c.fetchall()
you can wrap it in a class object.

Sorry for the elementary question: I was wondering if someone could
explain the difference to me between class and static methods. Coming
from other languages, I'm used to static methods, but not "class
methods". Thanks.

I'm having trouble loading an image into a Postgre database. The code is below
as well as the traceback in the apache log. Is something up with my
sqlStatement? Do I need to use something other than %s? How can I avoid that
type error?
Thanks,

Hello Chinook,
So is the main motivation for class methods so that you can have the
class object available? It seems you can have that anyway in a static
method by just asking. I'm sure there's a good reason for this, but I
haven't yet gotten to the point of mastery where I can see a need for

Its a standard string formatting operation in Python.
The % operator basically says substitute the values
in the folowing tuple for the marked fields in the
foregoing string.

You are correct.
What I will do is an instance method that calls the class method with
an optional parameter.
I don't know what I was thinking, I was just messing around with
nested classes for the first time and kind of forgot how to program.

I think you'll need to override the __getattr__ method.
It will pick up the call and you can test whether its a
class mrethod being called. I think...

No, a classmethod is passed the class that it is called on. If you have an

Hi I have a list of regular expression patterns like such:

Hi Wang,
You need to do what the shell does, all up the program directly, like this:
fork parent,
in the parent, reap the child
in the child, call exec() with the subprogram as the argument
Here's an example:
import os
program_executable = "/bin/ls"
parameters = ["/home/me/file1.txt", "/home/m
32 matches
