RE: [Tutor] (no subject)
by Glen Bunting April 8, 2001

April 8, 2001

Let me rephrase the question. I didn't state the question very clearly. I am trying to write a python script on Mandrake Linux that will check the amount of free memory available, similar to using the 'free' command. I already have a script written in sh which does this by calling the free command, but I am trying to re-write it completely in python.

If I had a script that I wanted to get feedback on, would it be okay to post it here? How long of one could I get away with? I just don't want to annoy anyone x days in the future... TNX

Still confused about Python references/objects
by Sheila King April 1, 2001

April 1, 2001

Even now, there is a discussion going on in comp.lang.python on this same topic. Anyhow, I've been working with Python for a couple of months now, and reading some books and online docs, and have written a few successful scripts that I use on my website or for email management. And I THOUGHT I had figured out this Python reference stuff (with respect to objects and names that refer to them). <sigh> But I managed to confuse myself again this morning. I really like how it is not necessary to write a "swap" function in Python. The whole "swap" procedure can be accomplished in Python with a single assignment statement using tuples. I saw this type of example in Wesley Chun's _Core Python Programming_ book. However, just for illustration, I was trying to write a swap function. And, I thought that all parameters were passed by reference. So, when I ran the following interpreter session, I was really surprised to find that my swap function actually swapped nothing at all: Python 2.0 (#8, Oct 16 2000, 17:27:58) [MSC 32 bit (Intel)] on win32 Type "copyright", "credits" or "license" for more information. IDLE 0.6 -- press F1 for help >>> x = 2 >>> y = 3 >>> print x, " ", y 2 3 >>> (y, x) = (x, y) >>> print x, " ", y 3 2 >>> def swap(a, b): (b, a) = (a, b) >>> swap(x, y) >>> print x, " ", y 3 2 >>> Could someone explain this to me? Why doesn't the swap function do anything? -- Sheila King http://www.thinkspot.net/sheila/ http://www.k12groups.org/

installing python 2.0 on redhat 7.0
by Steve A. April 1, 2001

April 1, 2001

Hello. Seems that to install python 2.0 on redhat 7 I'll need to reinstall glibc.. well, basically, considering all the file dependencies, it's just not worth it. I'm wondering if anyone has installed python 2.0 or 2.1 on redhat 7, and if there are any RPMS out there to make it a relatively painless process. Otherwise it looks like I'm going to have to go back to 6.2. argh! -Steve

Timer?

April 1, 2001

I was wondering how to make a timer in Python. Say every ten seconds, I want Python to print out a string of text. How might I do this? Britt -- It is pitch black.

Text Editor focus() help
by Corey Woodworth March 31, 2001

March 31, 2001

I'm trying to get my text editor to open a document in a new toplevel widget if the current widget contains text. It works fine but the focus sometimes reverts back to the previous window (and then sometimes it doesn't). How can I make sure that the new window always receives the focus? Here is my code: (its 142 lines long. I hope this doesn't offend anyone... I don't think it will after reading the posting scripts thread, but it still seems a bit edgy.
