Python 3.12.1 : Check proxies on network.

Simple example about how to check proxies in network ...

import socket

# Get IP 
hostname = socket.gethostname()
workstation_ip = socket.gethostbyname(hostname)
#print("workstation_ip : ", workstation_ip )

# Put your IP's proxies from network
proxy_ips = ["192.168.1.1", "192.168.1.2", "192.168.1.3"]

# check IP proxy
if workstation_ip in proxy_ips:
    print("Is a proxy on network")
else:
    print("Not network proxy")

Example with sockschain python module:

import socket
import sockschain as socks

# Enable debugging
def DEBUG(msg):
  print (msg)

socks.DEBUG = DEBUG
# This would have set proxies using the standard environment variables:
socks.usesystemdefaults()

# Configure a default chain
chain = [
  'tor://localhost:9050/', # First hop is Tor,
  'tor://localhost:8080/', # 8080 port,
  'ssl://proxy.example.com:8443/', # SSL to proxy.example.com
  'http://user:pass@proxy.example.com/' # ... try auth to an HTTP proxy
]
socks.setdefaultproxy() # Clear the default chain
for hop in chain:
   socks.adddefaultproxy(*socks.parseproxy(hop))

# Configure alternate routes (no proxy for localhost)
socks.setproxy('localhost', socks.PROXY_TYPE_NONE)
socks.setproxy('127.0.0.1', socks.PROXY_TYPE_NONE)

... the result is:

Python 3.10.7 : Krita and python - part 001.

Here is a Python script for Krita that will help you read the Python functions of a document.

Open a new document, create a python script, and add the source code. Use the main menu Tools - Scripts - Ten Scripts to choose the place where the script exists and the combination of keys for execution.

This is the source code:

from PyQt5.QtWidgets import QWidget, QVBoxLayout, QTreeWidget, QTreeWidgetItem, QTextEdit
from krita import *

class LayerContentDialog(QWidget):
    def __init__(self, content):
        super().__init__()
        self.setWindowTitle("Conținutul preluat cu dir():")
        self.setGeometry(100, 100, 800, 600)

        main_layout = QVBoxLayout()

        tree_widget = QTreeWidget()
        tree_widget.setHeaderLabels(["Nume", "Tip"])
        self.add_items_recursive(tree_widget, content)
        main_layout.addWidget(tree_widget)

        close_button = QPushButton("Închide")
        close_button.clicked.connect(self.close)
        main_layout.addWidget(close_button)

        self.setLayout(main_layout)

    def add_items_recursive(self, tree_widget, items, parent_item=None):
        for item in items:
            if isinstance(item, str):
                if parent_item:
                    item_widget = QTreeWidgetItem(parent_item, [item, type(getattr(doc, item)).__name__])
                    help_text = "\n".join(dir(getattr(doc, item)))
                    item_widget.addChild(QTreeWidgetItem([help_text]))

doc = Krita.instance().activeDocument()
layerContents = dir(doc)

dialog = LayerContentDialog(layerContents)

The result for this script is this:

You can use the main menu Tools - Scripts - Scripter to write, test, save, and run the source code.

Django builder is free to use, and a personal project worked on in my spare time.

Any donations are very much appreciated.

If you want to, feel free to donate using the BitCoin address or PayPal link below.

Here is a new online tool that allows you to create projects with the Django framework and manage them more easily. It comes with different versions of Django, you can include channels and HTMX.

I don't see a command line to manage the project...

Python 3.12.1 : Using the subprocess python module - part 001.

The subprocess module allows you to spawn new processes, connect to their input/output/error pipes, and obtain their return codes. This module intends to replace several older modules and functions:

See the official webpage for Python verison 3.12.3 same like version 3.12.1 I used.

Let's see two examples with this python module:

First script will get output of net users command and will parse all into a list:

import subprocess

def find_users():
    try:
        result = subprocess.run(["net", "users"], capture_output=True, text=True)
        users = result.stdout.splitlines()      
        # define list content         
        user_list = []
        for line in users[4:-2]:  # inser only some rows 
            #print(line) #only users        
            user = line.split()
            user_list += user
        # print the right result
        print(user_list)
    except Exception as e:
        print(f"Error : {str(e)}")

# run find_users
find_users()

The result is this:

python test_001.py
['Administrator', 'catafest', 'DefaultAccount', 'Guest', 'WDAGUtilityAccount']

This source code will show data from tasklist and will print result of this ... :

import subprocess

def find_processes():
    try:
        result = subprocess.run(['tasklist', '/v'], capture_output=True, text=True)
        output_lines = result.stdout.splitlines()

        for line in output_lines[3:]:
            columns = line.split()
            #print(columns)
            #if len(columns) >= 8 and columns[9] == 'N/A':
            if len(columns) >= 8 and columns[0] == 'tasklist.exe':
                print(line)
    except Exception as e:
        print(f"A apărut o eroare la găsirea proceselor suspendate: {str(e)}")

find_processes()

The result will be like this:

I used the IBM Quantum Platform and it provides an A.P.I symbol so that it can be used with the source code.

You can find this notebook at this catafest_061.ipynb repo file.

Python 3.12.3 : python and Federated Message Bus in Fedora Linux Distro.

A few days ago I tested this functionality named Federated Message Bus of the Linux distribution called Fedora.

Federated Message Bus is a library built on ZeroMQ using the PyZMQ Python bindings. fedmsg aims to make it easy to connect services together using ZeroMQ publishers and subscribers.

You can use this python package named fedmsg to use this functionality ...

This is the source code :

import fedmsg
from fedmsg import *

import os
# Set the routing_nitpicky flag to True
os.environ['FEDMSG_ROUTING_NITPICKY'] = 'True'


config = fedmsg.config.load_config([],None)
config['mute'] = True
config['timeout'] = 0

for name, endpoint, topic, msg in fedmsg.tail_messages(**config):
    print ("name ", name)

This is the result :

[mythcat@fedora FedoraMessaging]$ python fedmsg_001.py
No routing policy defined for "org.fedoraproject.prod.copr.build.start" but routing_nitpicky is False so the message is being treated as authorized.

Python 3.12.1 : aiohttp python package - part 001.

This python package named aiohttp provides asynchronous HTTP client and server functionality.

You can find more about this pytho package on the GitHub repo and the official page.

The last time I wrote about this python package was on Thursday, July 9, 2020 in this source code tutorial titled Python 3.8.3 : About aiohttp python package.

A few days ago I tested two python scripts that use this python packet.

One script makes a benchmark and the other uses cookie technology as a test.

Here is the script that makes the benchmark...

import timeit
from http import cookies

from yarl import URL

from aiohttp import CookieJar

def filter_large_cookie_jar():
    """Filter out large cookies from the cookie jar."""
    jar = CookieJar()
    c = cookies.SimpleCookie()
    domain_url = URL("http://maxagetest.com/")
    other_url = URL("http://otherurl.com/")

    for i in range(5000):
        cookie_name = f"max-age-cookie{i}"
        c[cookie_name] = "any"
        c[cookie_name]["max-age"] = 60
        c[cookie_name]["domain"] = "maxagetest.com"
    jar.update_cookies(c, domain_url)
    assert len(jar) == 5000
    assert len(jar.filter_cookies(domain_url)) == 5000
    assert len(jar.filter_cookies(other_url)) == 0

    filter_domain = timeit.timeit(lambda: jar.filter_cookies(domain_url), number=1000)
    filter_other_domain = timeit.timeit(
        lambda: jar.filter_cookies(other_url), number=1000
    )
    print(f"filter_domain: {filter_domain}")
    print(f"filter_other_domain: {filter_other_domain}")

filter_large_cookie_jar()

Here is the result obtained...

python test_bench_001.py
filter_domain: 59.85247729999901
filter_other_domain: 0.042927300000883406

Is more easier to understand code on how to use a cookie with this Python package using the httpbin website.

httpbin.org is a simple HTTP request and response service. It provides an easy way to test and inspect various aspects of HTTP communication.

Let's see the source code:

import asyncio
import aiohttp

async def main():
    urls = [
        'http://httpbin.org/cookies/set?test=ok',
    ]

    async with aiohttp.ClientSession(cookie_jar=aiohttp.CookieJar()) as s:
        for url in urls:
            async with s.get(url) as r:
                print('JSON:', await r.json())

        cookies = s.cookie_jar.filter_cookies('http://httpbin.org')
        for key, cookie in cookies.items():
            print(f'Key: "{cookie.key}", Value: "{cookie.value}"')

if __name__ == '__main__':
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        pass

The result of this running is this ...

python test_cookie_001.py
JSON: {'cookies': {'test': 'ok'}}
Key: "test", Value: "ok"

Python 3.12.1 : NiceGUI - UI framework over internet.

NiceGUI is an easy-to-use, Python-based UI framework, which shows up in your web browser. You can create buttons, dialogs, Markdown, 3D scenes, plots and much more.

The project can be found on this GitHub repo.

The default demo example from the official webpage works fine.

This is the source code I used.

from nicegui import ui
from nicegui.events import ValueChangeEventArguments

def show(event: ValueChangeEventArguments):
    name = type(event.sender).__name__
    ui.notify(f'{name}: {event.value}')

ui.button('Button', on_click=lambda: ui.notify('Click'))
with ui.row():
    ui.checkbox('Checkbox', on_change=show)
    ui.switch('Switch', on_change=show)
ui.radio(['A', 'B', 'C'], value='A', on_change=show).props('inline')
with ui.row():
    ui.input('Text input', on_change=show)
    ui.select(['One', 'Two'], value='One', on_change=show)
ui.link('And many more...', '/documentation').classes('mt-8')

ui.run()

I run with the python and you can see is visible in many places:

python test_001.py
NiceGUI ready to go on http://localhost:8080, http://x.x.x.x:8080, and http://x.x.x.x:8080

I tested the interpolate.Akima1DInterpolator changes with the default python script and works well:

import numpy as np
from scipy.interpolate import Akima1DInterpolator

import matplotlib.pyplot as plt
fig, ax = plt.subplots()

x = np.linspace(1, 7, 7)
y = np.array([-1, -1, -1, 0, 1, 1, 1])
xs = np.linspace(min(x), max(x), num=100)
y_akima = Akima1DInterpolator(x, y, method="akima")(xs)
y_makima = Akima1DInterpolator(x, y, method="makima")(xs)


ax.plot(x, y, "o", label="data")
ax.plot(xs, y_akima, label="akima")
ax.plot(xs, y_makima, label="makima")

ax.set_title('Fruit supply by kind and color')
ax.legend(title='Fruit color')

plt.show()

about Akima piecewise cubic Hermite interpolation.

Akima interpolator Fit piecewise cubic polynomials, given vectors x and y. The interpolation method by Akima uses a continuously differentiable sub-spline built from piecewise cubic polynomials. The resultant curve passes through the given data points and will appear smooth and natural.
