I'm guessing but how do you start Python? Could it be that you
are
sometimes starting it from the folder that the filesw are stored
in
and sometimres from some place else? Python will look in
"the current directory" for the files if you don't provide the
full path.

Note you used the full path first time but a relatoive path
second time.
Suggests you were not in

D:/Program Files/Python/Lib/idlelib/Saves

mouse_buttons()

How do I use that function? It's from Livewires . It returns three values, the middle , right, and left
button. Depending on whether it is clicked, it will return a 0 or 1. But how do I get it so that when I click on
the screen, it will stop? I've triedthis:

while 1:
  mouse_buttons()
  if mouse_buttons() == 1
    break

but... it doens't work

Hi Leung,

What does mouse_buttons() give back to us?  Is it a number, or a list,
or...?

I see that you're trying to guess this by seeing if it's an integer.  And
this is something that, with enough flailing, can be guessed with time.
But we can accelerate the process.  *grin*


Take a closer look at:

Hi Udz,

Just checking up on this: what happens if you add the line:

###
raw_input("Program finished: press Enter to continue...")
###

at the very end of your program?  I suspect that Windows is closing your
program down automatically.  t's a common issue for console-based programs
on Windows, that your program may actually be running fine, but may simply
be finishing too quickly for you to see it.

Many programs try to work around this window-closing feature by forcing a
prompt so that the user can see things.

Good luck to you!

Accessing the mailing list archive

Hi Tadey,

By the way, there's also an archive of the whole mailing list:

    http://mail.python.org/pipermail/tutor/

so if you ever want to browse some old threads, you can always turn to
that link.  Everything is saved to the archive, which is pretty useful.

There's also a rudimentary list searcher here:

    http://aspn.activestate.com/ASPN/Mail/Browse/Threaded/python-Tutor

and sooner or later, someone is bound to write a nicer search interface to
the archive.

Hello!

It sounds like you're trying to use ISO-8859-1 encoding to display
accented characters on your system.

If your terminal supports it, then you can use:

    ftp://unicode.org/Public/MAPPINGS/ISO8859/8859-1.TXT

to find out the right hexadecimal constants.  For example, the tilde 'n'
maps to the entry:

"""

class method: dynamic overload

Hi All:
    Is it possible in python to replace (overload)
an existing class method with a new one of the same
name but with different functionality?

I would welcome pointers to docs and keywords.
- this is just R & D, not mission critical.

TIA
tim

Hi Leung,

Livewires has a good explanation of dictionaries:

    http://www.livewires.org.uk/python/pdf/D-dicts.pdf

By the way, when you get the chance, take a quick glance through the other
reference sheets:
