Problem solved. So i made few mistakes, and the correct code is:


#!C:\Users\HP\AppData\Local\Programs\Python\Python310-32\python.exe

import os
import urllib.parse
import nltk

query_dict = urllib.parse.parse_qs(os.environ[‘QUERY_STRING’])
input_something = str(query_dict[‘someamountoftext’])[2: -2]
def tknz_wrd(someamountoftext):
return(nltk.word_tokenize(someamountoftext))

print(“Content-Type: text/html\n”)

print (tknz_wrd(input_something))

It processes data, recieved from browser line, like: http://localhost/speciallocation/local/tokenize/morgot.py?someamountoftext=Enter%20your%20text%20here

morgot.py - name of CGI file.

'?someamountoftext=' This is how you enter data into variable

%20 - spacebar in browser line.

Hi! I use python NLTK library in CGI script to tokenize some text in XAMPP web server. If i simply use:
someamountoftext = "someamountoftext someamountoftext someamountoftext" and then nltk.word_tokenize(someamountoftext) or nltk.sent_tokenize(someamountoftext) It will work.
BUT! If I use this:
import os
import urllib.parse
import nltk
query_dict = urllib.parse.parse_qs(os.environ['QUERY_STRING'])

def tknz_wrd(someamountoftext):
return(nltk.word_tokenize(someamountoftext))


print("Content-Type: text/html\n")
print (tknz_wrd)

It does not print anything on screen. No erros, just white browser screen.
I know it's not releted directly to apache, but maybe anyone encountered such problems before? Or I simply made some shamefully silly mistake......

I use: Apache/2.4.53 (Win64) OpenSSL/1.1.1n PHP/7.4.28
python 3.10.4

Thank you, very much, gsmith! It helped! Problem solved!

PassEnv APPDATA

Put it in httpd.conf if you want it available in all virtualhosts or inside any virtualhost you want APPDATA available for

Hi guys! I need to use python library named "NLTK" on XAMPP. But as i found, NLTK "has platform-specific path handling"(https://stackoverflow.com/questions/16609242/import-nltk-not-working-on-xampp) and Apache does not provide the proper environment(https://stackoverflow.com/questions/11219319/appdata-is-not-returned-in-python-executed-via-cgi).
I hardly looked at the documentation and links above:
1) https://httpd.apache.org/docs/current/env.html
2) https://httpd.apache.org/docs/current/mod/mod_env.html#setenv
3) https://httpd.apache.org/docs/current/howto/cgi.html
"If your CGI program depends on non-standard environment variables, you will need to assure that those variables are passed by Apache." Thanks, very 'helpful'. I cant understand HOW and WHERE exactly I need to do env. fixes.
My configuration: Apache/2.4.53 (Win64) OpenSSL/1.1.1n PHP/7.4.28 Server at localhost Port 80
I would be very grateful, if you give step-by-step instruction.

P.S. Sorry for bad english.

Davon konnte ich leider nicht viel verstehen. Welche Möglichkeit gibt es das Problem zu lösen?

Mit dem Ort des Scripts hat das weniger zu tun.
Es gibt Benutzerbezogene Variablen und Systembezogene Variablen. Die Benutzerbezogenen Variablen beziehen sich auf den Benutzer, mit dem der Prozess läuft, also zum Beispiel der Apache httpd Daemon. Wird dieser als Windows Dienst gestartet läuft dieser Standardmäßig mit einem SYSTEM Rechten, nicht in einem Benutzerkontext.

Hallo alle zusammen,

ich versuche Pythonscripte durch PHP Scripte zu verwenden. Das klappt auch alles ganz gut. Ich nutze XAMPP dazu. Jetzt habe ich aber folgenden Fehler:
Ich möchte gerne gmaps importieren. Er spuckt mir den Fehler aus: Exception: RuntimeError('Could not determine home directory.')

Wenn ich mit "print(os.environ)" mir die Umgebungsvariablen mit einer for-Schleife anzeigen lasse sehe ich folgende Umgebungsvariablen:

Code: Select all

Der Fehler kommt zustande, da in diesen Umgebungsvariablen kein "HOME" bzw in WIndows kein "USERPROFILE" enthalten ist. Ich glaube, dass der Grund ist, dass ich vom htdocs aus den Code starte. Dadurch zeigt der mir andere Umgebungsvariablen an als wenn ich den gleichen Code als normales Pycharm Projekt ausführe. Dann habe ich folgende Umgebungsvariablen:

Code: Select all

Hier ist Userprofile wieder enthalten.

Ich weiß nicht, was ich genau tun kann. Ich muss das Modul gmaps ungebingt importieren. Das will er aber nicht, weil er die Umgebungsvariable nicht findet. Gibt es eine Möglichkeit diese irgendwie hinzuzufügen?

Hallo und guten Tag, liebe Community,


ich bin auf der Suche nach einem geeigneten Ansatz - bzw. einem Sensor für PH-Messung (Wasser, Kaffee, u.s.w): DFRobot pH vs. EZO TM class embedded pH circuit

Das Ziel: ich will zu Demonstrationszwecken den pH Wert bestimmen in den Getränken - Wasser, Kaffee, Mineralwasser, Tee.
Am liebten wäre mir, wenn ich das nicht kalibrieren muss - vor jeder Messung. M.a.W. ich suche ein einfaches u. robustes Verfahren - in Verbindung mit dem Einsatz von Raspi, Arduino oder ESP32

Vorweg: In der Chemie ist der pH-Wert eine Skala, die verwendet wird, um anzugeben, wie sauer oder basisch eine Lösung auf Wasserbasis ist. gut: Saure Lösungen haben einen niedrigeren pH-Wert, während basische Lösungen einen höheren pH-Wert haben.
Somit hat der pH-Sensor die Fähigkeit, den pH-Wert jeder Lösung zu bestimmen, d.h. er sagt, ob die Substanz sauer, basisch oder neutral ist.

Der Ph-Sensor hat ein breites Anwendungsspektrum wie Abwasserbehandlung, Pharmazeutika, Chemikalien und so weiter - oder schlicht nur die Messung von Werten im Aquarium.
Mein Ziel: Ich möchte einen pH-Sensor entwickeln, der hilft, den pH-Wert in Flüssigkeiten wie Kaffee, Wasser, Cola, Bier und dergleichen zu messen.
Ich möchte eine kostengünstige Lösung haben, eine, die - wenn möglich - auch ohne Kalibirierung auskommt. Ich dachte hier an mehrere Optionen:

DFRobot Gravity Analog pH vs. EZO TM class embedded pH circuit


Frage: Kann ich den Gravity Ph Sensor mit Arduino verbinden?

Ich möchte ein einfaches Ph-Messgerät erstellen und den Ph-Wert auf einem OLED / LCD-Display anzeigen. Ich denke, dass ich mit diesem Projekt viel lernen kann; Etwas über den Aufbau und die Funktionsweise des Ph-Sensors.
Last but not least - wenn das System kalibriert werden muss (was ich nicht unbedingt haben "muss" - dann würde ich das halt auch noch "mitnehmen".
M.a. W. Dann lerne ich die Kalibrierungsmethode, die die Richtigkeit und Genauigkeit des Sensors bestimmt.
Aber - wie gesagt: eigentlich will ich gerne um das Kalibrieren herumkommen.
Wenn es denn geht.





Freue mich von Euch kurz zu hoeren.

PS. - update:

Habe noch was zum Dfrobot gefunden. Der würde mir wohl auch ausreichen was die Genauigkeit anbelangt:

Release of IPython 8.0 :: many new Features


https://blog.jupyter.org/release-of-ipy ... 034ff122ef

the authors on Jupyter.org just mentioned:

IPython is a powerful Python REPL that gives you tab completion, better tracebacks, multiline editing, and several useful features on top of pure Python Scripts. It is also the library that powers the Jupyter Kernel via the IPykernel.
Today I am pleased to announce the release of IPython 8.0, which has been long in the making and arrived a bit over three years after the 7.0 release. I also suggest to read the companion blog post on Quansight-Labs site that goes into some technical details on how we removed some old code. EDIT: You can also ask questions/comments on the jupyter discourse, or read the discussion on HN
Many new features
This major release comes with many improvements to the existing codebase and several new features. These new features are code reformatting with Black in the CLI, ghost suggestions, and better tracebacks which highlight the error node, thus making complex expressions easier to debug (see below).

head over to the page for more infos:

Hi!
I am on Windows 11 with XAMPP 3.3.0, and I use Debian on Windows Subsystem for Linux. I would like to use MySQL in XAMPP from WSL: is it possible?

More in detail, I develop a Python app in Flask (https://flask.palletsprojects.com/en/2.0.x/) which uses MySQL for database. I can launch the app from windows and it works fine, but when I launch it from Debian, it cannot connect to the database. The strange thing is that a few months ago it worked effortlessly, and now it does not work anymore. I have no idea what changed.
I could install mysql in Debian, but I liked that fact that I could use the same database from Windows and Debian for testing!

Thanks in advance!

pip and conda - where to use each of these options?

ever wondered how where to use pip and where to use conda:

- pip is a package-manager for python packages.
- Conda on the other handside - it is a packaging tool and installer that aims to do more than what pip does; Yes - conda can do lots of other nice things too.

for example:
- it can also handle library dependencies outside of the Python packages as well as the Python packages themselves.
- it can create a virtual environment, like virtualenv does.

to sume up: Conda handles both Python and non-Python installation tasks. We also can have Conda packages for C libraries, or R packages, and many many more things - or simply: really anything.
long speech short sense: Conda is the package manager of Anaconda, but it can do lot more: it can be used outside of Anaconda too.

but the usage of Conda is interesting - but some developers use other tools: here some thoughts regarding the various tools:
well there are existing lots of tools that help us to manage virtual Python environments: Venv, pyenv, pipenv, poetry, and we have to mention here also Docker, and of course also virtualenv - and last but not least conda.

in the following we start with explanations on the different things: pip, PyPI, venv, pyenv, virtualenv, or any other....

let us start with pip:
pip: so what is pip. pip is just the Python Package Manager.
well, we might think of pip as the general python equivalent of the ruby gem command - it is pretty similar

- but wait: pip is not included with python by default.
we may install Python while using homebrew, which will install pip automatically: brew install python
besides this we can find and publish python packages using PyPI: The Python Package Index ( https://pypi.python.org/pypi )

pip: Python packages only: it compiles everything from source

from the docs:
Python Packaging User Guide ....[...]...the Python Packaging User Guide, a collection of tutorials and references to help you distribute and install Python packages with modern tools. This guide is maintained on GitHub by the Python Packaging Authority. We happily accept any contributions and feedback. ??
Get started
- Essential tools and concepts for working within the Python development ecosystem are covered in our Tutorials section:
- to learn how to install packages, see the tutorial on installing packages.
- to learn how to manage dependencies in a version controlled project, see the tutorial on managing application dependencies.
- to learn how to package and distribute our projects, see the tutorial on packaging and distributing
- to get an overview of packaging options for Python libraries and applications, see the Overview of Python Packaging.

The requirements.txt file is comparable to the ruby gemfile: To create a requirements text file, pip freeze > requirements.txt Note, at this point, we have python installed on our system, and we have created a requirements.txt file that outlines all of the python packages that have been installed on your system.

PyPI this packages is not in the standard library: virtualenv (see https://pypi.org/project/virtualenv/ ) is a very popular tool that creates isolated Python environments for Python libraries. It works by installing a bunch of files in a directory (eg: env/), and then modifying the PATH environment variable to prefix it with a custom bin directory (eg: env/bin/). see for more infos here: https://pypi.org/project/virtualenv/ and besides this cf: the documentation: https://virtualenv.pypa.io/en/latest/

cf: the documentation: https://virtualenv.pypa.io/en/latest/


here we want to shed a light on some of the most interesting Conda commands:

Well - if you ever installed Anaconda-distribution - you have some options:

- you can take the GUI installer,
- you can use the command-line-interface

Let’s look at common conda commands to create and manage conda environments.
Everything is the same whether you installed Anaconda or Miniconda.

imagine you want to create a conda environments:

Code: Select all

conda create -n my_env pandas [jupyterlab]

Create a new conda environment named myenv with the latest version of Python available on the main conda channel. and yes: if you whish to do it on Jupyterlab then you just have to add the following snippet) [ Install pandas and jupyterlab packages to the environment - just that easy]

you can do either:

Code: Select all

-n is short for --name

what it does: well in this case conda just asks you here for a concrete confirmation - in other words it asks for the confirmation with any of the above mentioned package changes that are in question. What do you have to do here: well you just have to do one thing: just hit an press y when youre asked whether you want to proceed this process.

can create a new conda environment, with program biopython with this:

Code: Select all

conda create --name munich-townhall

lets go ahead: What if you just do not want to install any program at all? in this case you can specify one or more default packages for the installation while you are just creating the environment. This is a great option doing so: in other words this allows you to call conda create without directly and explicitly providing any package name at all:


to to a setting of the provided packages, you just need to call conda config like so:

Code: Select all

    conda config --add create_me_the_default_packages_here: PACKAGE_NAME

and besides this you also can set (and choose) a package name of just "python" to get a base, empty install.

Code: Select all

conda create --name myenv python

# or just run this if you want to use some python version especially.

Code: Select all

conda create --name myenv python=3.7

here some more conda - commands that are used quite very very often:

conda info --envs : # this lists all environments
source activate <env name>: # this command activates an environment you want to use
conda env remove -n <env name> : # with this command you can delete an environment
conda env export > environment.yml:# export conda environment requirements list to a certain file
source deactivate: # and this command just deactivates an environment - try it out!
conda list : # with this command you just are able to list all packages installed on your system.
conda create --name <env name> python=3.9 : # with this you can create new environment, and yes: you of course can specify version of python;



see some great ressources for the usage of Conda: just have a closer look at the following pages:

Create virtual environments for python with conda :: How to set up a virtual environments using conda for the Anaconda Python distribution

I'm trying to run a python script on a PHP script running on my XAMPP-VM Apache server but I am unable to access my python interpreter /usr/bin/python. My understanding is XAMPP uses its own ENV variables. How can I make my XAMPP-VM recognise my OS variables?

A PC with a network card and an online connection.

A webserver software like Apache, Nginx etc

Probably a SQL Database.
Probably a server side interpreter like PHP, Perl, Python

A registrated Domainname, plus a Domain Name Server.

Knowledge about DNS configuration, actually quite difficult for a newcomer.
Knowledge about Webserver (Apache) configuration, also quite difficult for a beginner and a huge amount of knowledge.

Eventually a FTP Server. Also with knowledge about configuration.

Manpower in order to allow 24/7 connection, especially when the server shuts down due to errors or hackers.

All this and much more you can get at webproviders (there are plenty of these in the WWW) starting as low as 2 or 3 € per month. You get preconfigured webspace, full maintenance, unlimited traffic and at least one domain name of your choice. Already the costs of energie running your home based server will exceed the costs of rented webspace. I strongly recommend to go for a webprovider of your choice.

Wenn das da steht, wird das auch so sein, warum denn auch nicht? Das sieht auch nicht nach Xampp aus.

Die SCRIPT_ALIAS Anweisung hat auch mit PHP eigentlich direkt nichts zu tun, die benötigt man, wenn man CGI Scripts egal welcher Art (das kann auch Python sein, oder Perl, oder ein .exe aus einem C-Programm usw., oder eben auch PHP Scripte, WENN man PHP als CGI Mode installiert hat) In ein eigenes Verzeichnis auslagern will. Mit ALIAS werden alle Dateien dort gesucht mit der entsprechenden URL, unabhängig davon ob es ein CGI Script oder sonst etwas ist.

BRAUCHEN tut man SCRIPT_ALIAS eigentlich gar nicht mehr, es gibt genügend Möglichkeiten, CGI Scripts auch ohne diese Anweisung auszuführen.
