I know you can create properties in a class that act like variables but you can do whatever you want behind the scenes, like calling the now() function on each access. A much more clear way to do this would be to create a function that calls the now function and just call your function whenever you want the value.

That's essentially Alan's suggestion, right? I've adopted it. See the
current state of the script I'm working on at
<http://tutoree7.pastebin.com/5XYaaNfp>. (I'll be posting a separate
question about it.)

Actually, at age 73 I have trouble remembering the [11:20] part.

>and in turn make your code more readable and logical? The problem with the approach you hint at is that then the function call is implicit. What if someone else wanted to use your variable in a tight loop? They don't probably expect or want your variable to automatically update itself.

Point taken, and instead I'm going with Alan's function. But also,
this script is only for my own use, and the calling of ctime()[11:20]
is just so I can see where the script is bogging down. Turns out the
problem is that the writing of the long string of digits gets close to
exhausting my laptop's memory. But that's for another thread.

I used to use it to time snippets at the command line. I've never used
it in a script. I'll check it out again. Usually if I time something
within a script I do it by using t0 = time() and t1 = time() and
printing the difference.

I don't think so.

Thanks, Luke.
