[Tutor] Python 3.7 Grids
Hi Looking for a way to use the determine the position of a card in a grid using the mouse click event in Python. Code is attached. There are no viruses. Unfortunately using Tinkter grids / frames can't determine between the two demo cards. Any suggestions are welcome -- Dave Merrick TutorInvercargill http://tutorinvercargill.co.nz Daves Web Designs Website http://www.daveswebdesigns.co.nz Email merrick...@gmail.com Ph 03 216 2053 Cell 027 3089 169 ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
[Tutor] path
A user has to type a path in the commandline on Win 10, so just a
string. This has to become a path / directory in the file system. Later
in the process subdirectories and files are 'appended' by the script. In
these files there are also paths, derived from the input path and they
have to use forward slashes. The tool that uses these files requires that.
# create structure:
# /---fullpath <-- input() cmd
# |
# /--- data
# /--- db
# |+--- basename.db3<-- pathlib.Path(...).touch()
# |+--- basename.read <-- forward slashes inside
# /--- ddl
# /--- doc
# /--- sql
# +--- basename.sublime-project <-- forward slashes inside (json)
# +--- _FOSSIL_
And here the misery begins...
A short excerpt:
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64
bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> inp = "c:\test\drive\this"
>>> import pathlib
>>> p=pathlib.PurePath(inp)
>>> p
PureWindowsPath('c:\test/drive\this')
>>> print(pathlib.PurePosixPath(p))
c:/ est/drive his
>>> inp
'c:\test\\drive\this'
>>> import os
>>> print(os.path.normpath(inp))
c: est\drive his
>>> print(pathlib.Path(inp))
c: est\drive his
>>>
how to go from a string to a path, how to append to a path (os.path.join
or / with Path), how to turn it into 'posix'
TIA,
Ingo

Most people don't use pathlib, and that's kind of sad, since it tries to
mitigate the kinds of questions you just asked. Kudos for trying.
For your example, when you define inp as a string, it needs to be a raw
string because otherwise Python will interpret the backslash sequences.
\t means tab, which is why the the results look mangled.
inp = "c:\test\drive\this"
If you're going to use pathlib, then may as well use the / operator for
joining,

Sigh... something dropped my raw string, so that was a really bad sample :( inp = r"c:\test\drive\this" On Sat, Jun 29, 2019, at 07:44, Mats Wichmann wrote: > > For your example, when you define inp as a string, it needs to be a raw > string because otherwise Python will interpret the backslash sequences. > \t means tab, which is why the the results look mangled. > > inp = "c:\test\drive\this" > > ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

As Bob Gailer mentioned this is a text only list which does not allow attachments, so I cannot see what you are actually attempting with your code. But with what you said, two thoughts come to my mind: 1) You can embed each card image on a button widget and if such a button is clicked have the button's callback function respond accordingly. 2) tkinter allows you to know the size of your window and can report back what the cursor's current position is. If you ensure that your cards take up a known coordinate space in the window, when a mouse click event happens you can write code to determine if the cursor fell within either card's known coordinate space. Hope this gives you some idea of how to tackle your problem. -- boB ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
