I’m not looking through all the packages you have installed

What version of python is installed on your system?

why reply to me instead of to the list?
It's generally considered bad form to do so.


Do you have any python 3 installed on your system?
Or python 2.7?
If not, can you install such via system package?

That should work on any system, with any system installl python.
It's not trying to modify the system installed python in anyway...

It has to go somewhere your shell can find it.  Mine is a shell

pyenv is not a 'global' package

there is a mountain of /root/.pyenv  files though
there is also quite a number of /root/.pyenv/plugins/pyenv-virtualenv/
files

when looking in the /root/.pyenv files I can find options for all the older
version of python
but none for anything newer than what is on my system

is there something else to install to achieve this 'version freedom' that
pyenv promises?

What? Yes, the *system* pip should have some restrictions, if it's a
system mainly managed by a package manager.

Setting up a venv is the *expected* approach to such situations, and
creating one doesn't cause any problems. You end up with a pip in the
activated venv that's going to install to a different path (the one in
the venv), and will not be marked as externally managed, as the package
manager has no control over that path.

That's the whole point.  What error are you getting?  The venv
module is
not the pip module so restrictions on the system pip have nothing to do
with it.

set up pyenv
activated a venv
trying to install python3.12 into it

1. download of python3.12 (blahblahblahetc).deb will not install
2. download of python3.12.tar.xz similarly will not install

(venv2) memyself@devuanbigbox:~$ pip install 
/home/memyself/Downloads/Python-3.12.4.tar.xz

Processing ./Downloads/Python-3.12.4.tar.xz
ERROR: file:///home/memyself/Downloads/Python-3.12.4.tar.xz does not 
appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' 
found.


seems that I need a different version (installable as it were) of 
python3.12

or my approach is all wrong!



you can't install Python "into" a venv.

you use a version of Python as the base when *creating* a venv, the venv 
will use the same binary as the base python (symlinks if possible, as in 
the Linux case), but with different paths.


Since you've already got pyenv, use it to build the version you want to 
use - I think you said there wasn't a deb for 3.12 in your distro? 
That's something like


pyenv install 3.12.4

that will use the build recipe it has... and hopefully work.  Distro 
Pythons sometimes have some strange setups that are hard to reproduce. 
Pyenv knows how to build micropython, too, should it ever come to that.


If you indeed found a deb for the right Python, use apt to install it, 
and then use *that* Python to create your venv.


If you have the pyenv-virtualenv plugin, you can ask it to make the 
virtualenv for you, if pyenv built the Python

Your approach is wrong.
You don't build python from source using pip.

You don't install new versions of python into a venv either.

Have you read the following?
https://docs.micropython.org/en/latest/esp8266/tutorial/intro.html

That seems to have instructions for what you want to do..

seems that I need a different version (installable as it were) of

To get a different Python "in" the venv, you use the version you want in

Python 3.13.0b4

What? Yes, the *system* pip should have some restrictions, if it's a 
system mainly managed by a package manager.


Setting up a venv is the *expected* approach to such situations, and 
creating one doesn't cause any problems. You end up with a pip in the 
activated venv that's going to install to a different path (the one in 
the venv), and will not be marked as externally managed, as the package 
manager has no control over that path.


That's the whole point.  What error are you getting?  The venv module is 
not the pip module so restrictions on the system pip have nothing to do 
with it.

I like uptime and not measured in hours either so I'm presently not running
Devuan 5
or testing - - - although I used to. Just found that I didn't need the most
recent versions
of most of the tools I was using so find the stability (except for the

Well - - - pstool was available in a version that worked in Devuan 3,
psytool is available in a version that works in Devuan 4 - - - beyond my
pay

First question answered earlier.
If I installed python 3.12 from source I would create a hung system for
myself.

Couldn't you just upgrade to Devuan 5, then?

It seems weird that something would work with the (presumably) older
version of Python in Devuan 3 and the (presumably) newer version of
Python in Devuan 5, but not with the version in Devuan 4.

You need to install Python first to create a venv. AFAIK there is no way
to set up a venv first and then install Python into it.

Does Devuan have a testing or unstable suite? You might be able to
install a newer Python version from that. If not your best bet is to
install Python from source.

Not really - - - it takes a computer with psytool and about 5 or 6 other
python3.12
programs to load the microcontroller.
It is in writing the program for the microcontroller that micropython is
used not at
all in the loading.

My question was, is and will be (and the doc absolutely doesn't cover it)
how do I install a different version in the venv so that python 3.11.x on
the
system is not discombobulated by the python 3.12.x in the venv.
That python 3.12 would let me run the tools needed.
(Its the how to install the next version of python that I just haven't been
able to find information on - - - and I would be looking for information
on how to install on a *nix.)

Will give python-poetry a look.

Have been looking at pyenv but that seems to be a whole rat's nest of other
stuff to install and its using a bunch of different tools to get there - -
- is it
necessary - - - yes or no (in the running of multiple python versions on
the
same machine).

Not really.

A computer that has psytool + about 5 or 6 other python 3.12 tools is
needed to load
the microcontroller so I don't see how having venv in the microcontroller
would help the
loading of software onto the microcontroller.

Have just come from a discussion about 'how to start a project'. Amongst
the questions to ask are: "what resources do we have (or can add) to
achieve?".



Fair question details interleaved - - -



In this case, if Python-skill is a "personnel-resource" (and C++ a

Well - - - RPi world technical specs is usable from -20 to 60 C (iirc on

range.


Interesting, but creates a mis-match of tools - battles for you to fight...



Why talking of Python 3.12 when the solution involves MicroPython?



Because one uses psytool on one computer to transfer a program to the
MicroPython system.  In fact there are a set of tools that need Python3.12
to be able to do this and therefore the question.




Perhaps need to take a step back and look at 'options' - relate needs to
resources, and evaluate the impact of each decision on later ones - as
well as against your personal skills (modify objectives to limits, or
accept that some learning/training will be necessary as pre-requisite to
(being able to) attack the project).

I have been investigating using a venv but am not finding clear directions

so
that I could set up Python3.12 inside (along with the other needed tools).
The
more I'm looking the less useful most of the information I'm finding is
becoming.
Therefore I thought I would go to the python gurus for information - - -
which I
have.

So please - - - how do I set up a venv so that I can install and run python
3.12
(and other needed programs related to 3.12) inside?


If you mean venv itself, which "directions" have you reviewed?
This one (https://python.land/virtual-environments/virtualenv) seems 
very straight-forward and shows "What's inside a venv?" to include 
python.exe. Given that venv is more-or-less the official/traditional 
solution, what are you doing differently - perhaps the question is 
lacking detail.

(see also @Cameron's take)

Personally, I'm using Poetry (https://python-poetry.org) which seemed 
just as easy to pick-up; plus pyenv to maintain multiple versions of 
Python on one machine.

Sorry if this offends, but this is a list of short-cuts and reasons why 
they don't work (immediately).



Have just come from a discussion about 'how to start a project'. Amongst 
the questions to ask are: "what resources do we have (or can add) to 
achieve?".


In this case, if Python-skill is a "personnel-resource" (and C++ a 
"constraint"), will question the ESP over Raspberry Pi (say)?


Why talking of Python 3.12 when the solution involves MicroPython?


Perhaps need to take a step back and look at 'options' - relate needs to 
resources, and evaluate the impact of each decision on later ones - as 
well as against your personal skills (modify objectives to limits, or 
accept that some learning/training will be necessary as pre-requisite to 
(being able to) attack the project).

That's too bad. Normally a Python install on Windows is trouble free.
Perhaps we can help.


I have installed, and un-installed several versions of Python


Please give more information.  What versions of Python, where did you
get it, how did you install it, what options if any did you choose
during the installation?


and was able to complete the first two lessons in the attached book,
but could not complete lesson 3 (Turtledemo)...Some of the error

"Unable to initialize device PRN"; “Python is not recognized as an
internal or external command”: "Python was not found: run without
arguments to install from Microsoft Store, or disable this shortcut
from settings mange, app execution aliases:"


You need to tell us just what you have done.  What was this "lesson" 
supposed to do?  Did you try to run it while you were working in 
PyCharm?  Just how did you try to run the lesson?



...I have been at this
for 4 days now at least three hours each day...Any information or
help you can provide would be greatly appreciated.  Additionally, I
do have PyCharm installed (As you can tell, I am a beginner), is
PyCharm the same thing as Python?  Thank you in advance!


No, PyCharm is an editor and Python IDE; it is not the same as Python.
Python is a programming language.  The problems you have been having 
could be caused by PyCharm not being set up to work with your 
installation of Python.


To see if Python has been installed correctly, open a Windows console. 
If you don't know how, one way is to hit the Windows key and type "cmd". 
 Windows will offer "Command Prompt".  Hit the ENTER key to accept it, 
and a console window will open. (There are more convenient ways, but we 
don't need to get into them right now).


In the console window, type (without the quotes) "py -V".  You should 
see something like this (The first line is what I typed, the second line 
is the response):


C:\Users\tom>py -V
Python 3.10.9

If this works, Python has been installed and apparently working.

If it is working, save the Python program from your lesson as a file 
with a name such as such as "lesson1.py". In an open console window. try 
to run it by typing


py lesson1.py

Instead of just "lesson1.py", you will either need to change directory 
(using the cd command) to the directory that contains that file, or you 
will need to use the full path to the file.  For example, if the file is


c:\temp\python\lesson1.py

then run it by typing

py c:\temp\python\lesson1.py

Let us know how it goes.

This list strips attachments such as images, so I don't know which book

I'd go for Python 3.11 and the installer "Windows installer (64-bit)" at 
https://www.python.org/downloads/release/python-3112/, i.e. 
"https://www.python.org/ftp/python/3.11.2/python-3.11.2-amd64.exe"; 
(assuming that it's a 64-bit PC).
To run Python, the recommended way is to use the Python Launcher, py.exe 
(so type "py my_program.py" in a Command window), or just double-click 
on it if it's a GUI program.


As for PRN, that's the printer. Does anyone use PRN these days?

And, no, PyCharm is not the same thing as Python. PyCharm is an IDE 
(integrated development environment) for Python, but Python is its own

If you installed the conventional way, use the command name "py" instead 
of "python" to run things from a command shell.  Alternatively, you 
could try an installation of Python from the Microsoft Store (as the 
little stub program named python, which Microsoft preinstalls for the 
express purpose of giving you this hint).  There are times when getting 
Python working without hassle is easier when going that route.


You *can* add python to the search PATH, there's an option in the 
installer (you can rerun this from the Apps & features Settings 
applet)... in the screen for advanced options there's something that 
says "Add python to environment variables" or similar wording.

No. It's an "integrated development environment" - editor, debugger, 
source control wrangler and many other things.  It still needs to have a 
working Python installed. It will probably find the installed Python 
more easily than you will.  The concept of an IDE is you can do all your 
programming work without leaving it - you don't have to hop between 
editor, command line, and invoke other tools.  PyCharm is only one of 
many entrants in this space for Python programmers.  It's excellent, but 
I find it rather, ummm, "bulky", for beginners - there are a ton of 
features you'll not use early on in your journey, and thus I find it 
makes it much harder to find the things you do need in menus, help, etc. 
Up to you whether you push ahead with using it now, or leave it for a 
bit later when you're doing more complex things.


We have no idea what book you're using, by the way, as the list strips 
images and other attachments.  In any case, there are hundreds of Python 
books out now, most of us don't know about a particular one (unless we 
wrote it :) )

I doubt that will work; "django-admin" is not a valid module name.


Joey, there should be a folders called "bin" and "scripts" (or something
like that) in your Python installation. One of them, I expect, will
contain a django-admin.exe. (Or .bat? Or .cmd? Whatever.)
Adding these folders to your PATH environment variable (don't ask me
how) will solve these problems. IIRC you can do this for PowerShell
specifically or for Windows in general, whichever you think is best.

Which IDE (aka: fancy text editor) are you using to write this
code?

About what?

(!) Do you want to change the colors of the syntax
hilighting?

(2) Do you want to know how to prevent or fix syntax errors?

(3) Something else entirely?

Unfortunately last weekend i had to pawn my crystal ball to
payoff the vig, (it seems my financier is not the type to
just "fuggetaboutit") so i'm afraid you'll have to be a
_little_ more specific when asking questions. But seriously.
:-) Syntax hilighting is used by some editors to help a
programmer differentiate between certain elements of code.
And this hilighting can be very helpful to the beginner.

> How do I know the error and effect it?

Oh, you'll know when you make a mistake, because Python will
throw an error message. For instance, if you type "aaa"
(without the quotes) at the Python command prompt, you'll
receive a message that looks similar to this:

Traceback (most recent call last):
  File "", line 1, in 
aaa
NameError: name 'aaa' is not defined

This one is easy to diagnose. But in order to understand
Python exception messages you need to read some tutorials.
If you think you can start writing code (even Python code)
without some sort of "guide", then you're going to have a
real difficult time. Even folks with prior programming
experience need a guide. I imagine it would be like a
delivery driver moving from Paris to London and trying to
navigate around the streets of Merry ol' London using a map
of Paris. It's just not practical.

By utilizing Python, or any other programming language that
is available (and boy, there are quite a few of them!), you
can program your computer to do just about anything you
want. Maybe you could even write a real life HAL5000! But if
you're expecting that your experience with Micrcosoft Excel
formulas will translate over into Python, well, then, you're
in a tough time. Excel is a "single purpose software"
whereas Python is a "general purpose programming language".
Using Python, you could write a spreadsheet program like
Excel. Although I wouldn't suggest it, as there are already
tons of them freely available, and Python is not the best
language for something like that, and Microsoft would not be
too happy about it. But you could do it if you were so
inclined. My advice is that you visit the Python.org website
and look through the list of tutorials for absolute
beginners. After completing a few of these tutorials, you
should be off and running in no time. Here is link:

https://wiki.python.org/moin/BeginnersGuide/NonProgrammers

After clicking the link, skip down to the section titled
"Tutorials and Websites", and start with "One Day of IDLE
Toying". IDLE is a "fancy text editor" that ships with
Python, and this tutorial is very gentle on beginners. After
you have finished "One Day of IDLE Toying", my next
suggestion would be "A Byte of Python", which will introduce
you to some basics. From there, you can go through all the
other tutorials. When you have finished all the beginner
tutorials, then take a stab at the advanced section. Here is
a link

And don't forget, Google is a programmers best friend.

Who surprisingly, hardly ever complains.

Which unfortunately, is something i cannot say for the women
i have known. But i digress! O;-)

You'll have to learn the language if you want to do anything meaningful with it.
Python isn't anything like excel formula's, it is a full general multipurpose
programming language.  If you make a mistake, it usually is almost impossible 
to deduce
what you meant to write instead. (because otherwise we wouldn't have to program 
our
computers anymore and instead let them figure out automatically what we wanted 
to do,
right? Just joking)

Because you are comparing it to excel formulas: are you sure you've chosen the 
right
tool for whatever the task is that you wanted to solve?
If so: may I suggest first working through the Python tutorial.

If there's a syntax error, it'll tell you what the error is.

If it's merely showing parts of a line in different colours, that's 
"syntax colouring". In IDLE, for example, comments are shown in red and 
string literals are shown in green.

I'm not familiar with the book, but by "start menu" might it mean the
*Windows* start menu?

I am using the Python Programming third edition for absolute beginners. 

I was able to create my Game over program, but I do not have the start menu 
with the icons and cannot seem to find it. I have the Shell and the script mode 
but I am not able to find the start menu with the icons the book speaks of. 
When I try to edit the Idle/Shell screen I cannot. 


I am un installing and going to re-install, but wanted you to be aware.

class starts a class definition. def starts a function (or method) 
definition. The parser expects these definitions to be followed by one or 
more indented lines being the code of the class or function (method).

The following lines down to either a return or the next function 
definition line should probably all be indented.

eg:

class EventHubClient(object):

def sendMessage(self,body,partition):
eventHubHost = "pac-ns.servicebus.windows.net"
httpclient = _HTTPClient(service_instance=self)
sasKeyName = "SendPolicy"
sasKeyValue = "erENqf/5wdWCNEbCA9NsDIRqd5MRKdkii07+wezl/NU="
.. more indented code should probably follow

Getting the indentation correct is absolutely critical in Python.

and 'def' is not indented as it must be.  This must be covered in the

Indentation is crucial information in Python code. If it is lost, don't
waste time trying to guess it; instead, get the correct code.

How did you download it? You should download the code as a “plain text”
file.

Indentation issues with python

[syed khalid]

 I downloaded this code and am attempting to run it. I keep getting
indentation error. there is a way to handle it with a editor which can
recognize the tab or space issue. I have tried different options such as 2
or 3 spaces or tab to no avail.

I have encased the error mesage with line 23 between ""

import sys
import azure
import socket

from azure.servicebus import (
_service_bus_error_handler
)

from azure.servicebus.servicebusservice import (
ServiceBusService,

from azure.http import (
HTTPRequest,
HTTPError
)

from azure.http.httpclient import _HTTPClient

class EventHubClient(object):
def sendMessage(self,body,partition):eventHubHost =

Issues with python/libtcod

[Graham Fielding]

Hey, all. I'm trying to program a roguelike, using the wonderful tutorials 
written by João F. Henriques (a.k.a. Jotaf), but I've stumbled onto a bit of a 
problem setting up the game's inventory system, and I was hoping someone could 
help me out. Here's a code snippet, including the affected line. #def 
menu(header, options, width):
#if len(options) > 26: raise ValueError('Cannot have a menu with more than 
26 options.')
 
#calculate total height for the header (after auto-wrap) and one line per 
option
#header_height = libtcod.console_height_left_rect(con, 0, 0, width, 
SCREEN_HEIGHT, header)
#height = len(options) + header_height
In a nutshell: def menu() is an all-encompassing 'menu processor' function -- 
it contains a standardized menu layout that can be called, from anywhere in the 
stack, to create a generic menu. When I launch the game to check things out, 
everything runs smoothly until I try to open the inventory window -- at which 
point, IDLE  tosses up an AttributeError:
File "C:/Python Project/Roguelike.py", line 602, in 
player_action = handle_keys()
  File "C:/Python Project/Roguelike.py", line 531, in handle_keys
chosen_item = inventory_menu('Press the key next to an item to use it, or 
any other to cancel.\n')
  File "C:/Python Project/Roguelike.py", line 487, in inventory_menu
index = menu(header, options, INVENTORY_WIDTH)
  File "C:/Python Project/Roguelike.py", line 447, in menu
header_height = libtcod.console_height_left_rect(con, 0, 0, width, 
SCREEN_HEIGHT, header)
AttributeError: 'module' object has no attribute 'console_height_left_rect' 
I've tried moving the entire def menu() function to various sections of the 
stack, I've changed its arguments manually, and I've even removed the affected 
line entirely to see if that would help; nothing seems to work, and it's only 
when def menu() is called that this happens. Anyone got any ideas what could be 
going flooey?--

Either rename the script "opengui.pyw" or start it explicitely using:  
pythonw d:\opengui.py

pythonw.exe doesn't create a console (what you call a "DOS BOX").

Issues with Python + Batch File

[tarun]

Hi All,
I've a batch file which invoks a python file. The python code in the file
brings up a GUI. The GUI is of a test tool which can execute scripts.

I tried using the following 2 sample of code for my batch file:

* (1)   (2)*
D:\opengui.py  D:\opengui.py
goto:end   goto:end
:end   :end
EXIT   TASKKILL /IM C:\WINDOWS\system32\cmd.exe

Double clicking on the batch file brings up a DOS BOX which opens up the
GUI. On Closing the GUI, the DOS BOX both get closed. But if I close the GUI
when a test is under execution, the GUI gets closed but the DOS BOX still
remains open.

I want to some how close the DOS BOX when the GUI is closed.

Thanks & Regards,
Tarun
