I don't know (now) how to solve your challenges below. But if I were
trying to figure this out, I would try to find more complex tkinter
example applications that contain some of the issues I'd be interested
in. Then I would dig into the code, find the relevant pieces, and
then start playing with
I'm looking for ideas here.
A working solution for my sudoku solver is a 9 x 9 grid of entry boxes but it
looks a bit basic. So I created a 9 x 9 grid on a canvas which looks much
better. I can display digits in the centre of the squares but entering the
digits from the keyboard seems to be bey
You most likely have no file named words.txt in the directory from
which you are running your code.

Hello,
How do I avoid this error message everytime I utilize wordlist =
open("words.text") ?
>>> wordlist = open("words.txt")
Traceback (most recent call last):
File "", line 1, in
wordlist = open("words.txt")
FileNotFoundError: [Errno 2] No such file or directory: 'words.txt'

Having read Steven's post I'll retract the bit about
it being not that hard! :-)
But I still think its a fairly rare scenario. Until
Hello,
I have recently started using python and i have come to a halt while writing a
code and i was hoping someone out there can help me.
I am attempting to store a stream of data directly from a serial port onto
multiple files in sequence after x amount of time is elapsed.
for example :

No, my simple code only "works" for read-only properties and only as long as
you don't overwrite the property by assigning to the attrib

don't expect it to be that simple. People

Pretty much everything inn SQL land uses cursor objects.
It's why best practice creates an explicit cursor for
executing statements rather than the impl8ici

Probably because it is such a rare use case and because
its not that hard to do yourself if you really need it.
But the standard library, like any open source pr
Thank you Alan, Steven and Peter,
So, this call:
connection.execute("SELECT * FROM BRIGHTEST")
returns a , not a regular python
sequence. I did not know that. And, the connection must still be alive
when you iterate it.
That is a very important tidbit of info.
