Thank you.


Have you tried using pip via the Python Launcher?

py -m pip

That's installed by default by the installer from python.org.


To elaborate, Python might have been installed using an installer from 
python.org, from the Windows store, or in some other way.  "py" may only 
be available for a python.org installer.


In general, you would do best to always launch pip with the command

pythonx -m pip

where "pythonx" means the command that launches the version of python 
you want to work with.  This might be "py", "python3.11", "py -3.11", or 
something else, so use what you will be using on your system.

The page I was thinking of is

https://pip.pypa.io/en/stable/installation/

I found it by an internet search for "pip installer".  It covers several 
ways to install pip on Linux, MacOS, and Windows. On Linux, use it for 
Python installations that were *not* installed by the system.  Use the 
package manager if the Python installation or upgrade *was* installed by 
the system.


That Redhat link basically uses the pypa.io instructions.

Sorry, Rich, I've never dealt with this so someone else will have to 
give suggestions.


I would try to see if there are any versions available.  It could be 
that meson says it needs version x but only version y > x is available. 
Pip will quit but meson may very well work with the available version 
anyway.  So I would try to install pkg_resources on its own, and then 
see if the meson build can succeed.  No guarantees, but I've seen this 
work before.  So


python3.9 -m pip install --user pkg_resources

Or, to see what versions if any are available:

python3.9 -m pip install --user pkg_resources==
# NO spaces allowed before the "==".

There is a pip option to ignore the version specification and just leave 
the existing package installed as is, and this could help if the full 
installation wants to downgrade the pgk_resources that you just installed.


You can also use the --dry-run option to see what would happen without 
actually changing anything.

In my experience, on Windows pip is always included but on Linux hardly 
ever.  I have always needed to install the system installer pip package 
or get it from the pip site, depending, as I wrote earlier, on whether 
your version of Python was installed by the system or not.

a dozen VMs over the last few years].

Have you tried invoking pip _via_ Python? This is actually the 
recommended approach because it uses the pip for that specific Python.  
Example:


py -m pip install foo

This invokes the "pip" module for thePython invoked by "py" (which I 
believe is how Python is normally invoked from a Windows command line), 
to install some package "foo".

Thomas,

I probably last used pip with a python-3.7 version.


To check your version of Python, run
python3 -V


$ python3 -V
Python 3.9.10


Then try to run pip:
python3.9 -m pip


$ python3.9 -m pip
/usr/bin/python3.9: No module named pip

If pip has not been installed (very possible on Linux), then you will need to 
get it.  If python3.9 is not the system-upgraded version, then do an internet

If it appears that python3.9 *is* the version installed by the system, then 
use the system installer to install the right version of pip - as I said 
above, the package name can vary across distros.

What is there to clean up?  If you have Python 3.9 installed, why are 
you fooling around trying to run Python 3.7? It seems you are not 
telling us something ...


It's better to always run pip with the version of Python that you intend 
to use.  If that is launched when you type "python3", then run pip this way:


python3 -m pip

If instead you want to use, say, python3.9, then type this:

python3.9 -m pip

the csv export code runs through a different path than the ctrl_c code, 
one operating on the sheet level, one on the main table level (I didn't 
dig in to the depths but my assumptions would be that main table doesn't 
mathematically consider the headers in the same way).


def yield_sheet_rows in _tksheet.py vs def ctrl_c in _tksheet_main_table.py

Comparing how the each path functions, without a larger redesign of 
tksheet, you could create a custom button press combo binding to 
something other than ctrl-c utilizing the yield_sheet_rows (or - 
disallow all other ctrl-c functionality in favor of ONLY a csv style 
everything dump when using ctrl-c):


Import these:
import csv as csv_module
import io

This would be your custom binding functionality:
rows = self.sheet.yield_sheet_rows(get_header = True, get_index = False)

s = io.StringIO()
writer = csv_module.writer(s, dialect = csv_module.excel_tab, 
lineterminator = "\n")

for row in rows:
writer.writerow(row)
self.clipboard_clear()
self.clipboard_append(s.getvalue())

It would need something deeper if you wanted to integrate it to ctrl-c 
and keep the existing ctrl-c functionality

First thanks for drawing my attention to tksheet. I've long

it will do all I need.

As to copy/paste I couldn't see any explicit mention but
it does say the underlying data is in a Tk Canvas so it may

I have not used tksheet, but in its documentation at 
https://github.com/ragardner/tksheet/wiki#14-getting-selected-cells, 
there is the method


get_currently_selected()

Returns namedtuple of (row, column, type_) e.g. (0, 0, "column")
type_ can be "row", "column" or "cell"

There are companion methods for rows, columns, etc.  That would be a 
good starting point.

[Python-announce] attrs 23.1.0

[Hynek Schlawack]

I’m happy to announce a new release of attrs!

attrs is the direct ancestor of – and the inspiration for – dataclasses in the 
standard library and remains the more powerful toolkit for creating regular 
classes without getting bogged down with writing repetitive boilerplate code: 




(alternatively, see  for a 
richer-formatted version of the following)


Backwards-incompatible Changes

-   Python 3.6 has been dropped and packaging switched to static package data 
using Hatch. #993

Deprecations

-   The support for zope-interface via the attrs.validators.provides validator 
is now deprecated and will be removed in, or after, April 2024.

The presence of a C-based package in our developement dependencies has 
caused headaches and we're not under the impression it's used a lot.

Let us know if you're using it and we might publish it as a separate 
package. #1120

Changes

-   attrs.filters.exclude() and attrs.filters.include() now support the passing 
of attribute names as strings. #1068

-   attrs.has() and attrs.fields() now handle generic classes correctly. #1079

-   Fix frozen exception classes when raised within e.g. 
contextlib.contextmanager, which mutates their __traceback__ attributes. #1081

-   @frozen now works with type checkers that implement PEP-681 (ex. pyright). 
#1084

-   Restored ability to unpickle instances pickled before 22.2.0. #1085

-   attrs.asdict()'s and attrs.astuple()'s type stubs now accept the 
attrs.AttrsInstance protocol. #1090

-   Fix slots class cellvar updating closure in CPython 3.8+ even when __code__ 
introspection is unavailable. #1092

-   attrs.resolve_types() can now pass include_extras to 
typing.get_type_hints() on Python 3.9+, and does so by default. #1099

-   Added instructions for pull request workflow to CONTRIBUTING.md. #1105

-   Added type parameter to attrs.field() function for use with 
attrs.make_class().

Please note that type checkers ignore type metadata passed into 
make_class(), but it can be useful if you're wrapping attrs. #1107

-   It is now possible for attrs.evolve() (and attr.evolve()) to change fields 
named inst if the instance is passed as a positional argument.

Passing the instance using the inst keyword argument is now deprecated and 
will be removed in, or after, April 2024. #1117

-   attrs.validators.optional() now also accepts a tuple of validators (in 
addition to lists of validators). #1122

Hello All,

I found this small group in a google search, so not sure if it is still active 
but giving it a try nonetheless.

I have recently created a tkinter app and need the ability to copy and paste 
data from tksheet table into an Excel file. I do have a button for export, but 
it will be beneficial to also allow the user to simply copy,paste.

I have enabled the appropriate bindings but cannot find a solution to also

My table is generated after a query is run. Here is a small snippet.

  df = pd.read_sql_query(query, conn)
 results_table.set_sheet_data(df.values.tolist())
 results_table.headers(df.columns.tolist())
 results_table.enable_bindings(

"right_click_popup_menu",

"paste",
"undo"

I am not sure how to solve your problem. The newsgroup may not be able 
to wait for an answer, so I suggest that you go to Stack Overflow to ask 
questions after conducting a thorough Google search. Of course, you can 
also wait for someone who knows the answer to come and answer:D
