Update the new release of pip is available: 25.0.1 -> 25.1.1 , run this command:
python.exe -m pip install --upgrade pip
The documentation can be found on the official website.
pip install manim

Let's see how can be used to see the help area:
python.exe -m manim render --help
Manim Community v0.19.0

Usage: python -m manim render ...
Let's use this source code:
from manim import *

class AdvancedAnimation(Scene):
    def construct(self):
        # Scene 1: Introduction
        title = Text("Advanced Animation with Manim").scale(0.76)
        self.play(FadeIn(title))
        self.wait(2)

        # Scene 2: Custom Animation
        circle = Circle().set_fill(color=BLUE, opacity=0.5)
        square = Square().set_fill(color=RED, opacity=0.5)
        self.add(circle, square)
        self.play(
            Rotate(circle, angle=TAU),
            Rotate(square, angle=-TAU),
            run_time=2,
            rate_func=linear
        )
        self.wait()

        # Scene 3: Text Animation
        text = Text("This is a custom text animation", font_size=40).to_edge(UP)
        self.play(Write(text), run_time=2)
        self.wait()

        # Scene 4: Shapes Manipulation
        triangle = Triangle().shift(RIGHT * 2)
        self.play(GrowFromCenter(triangle), run_time=1.5)
        self.wait()

        # Scene 5: Transition to next scene
        self.play(Uncreate(triangle), FadeOut(text))

        # Scene 6: Final Animation
        final_text = Text("This is the end of our animation", font_size=50).to_edge(DOWN)
        self.play(FadeIn(final_text), run_time=1.5)
        self.wait(2)

# Run the animation
AdvancedAnimation()
Use this command to render:
python.exe -m manim render manim_test_001.py AdvancedAnimation -p
AdvancedAnimation -p

Python 3.13.5 : Get bookmarks from Edge browser with python.

Today I tested with these python modules json and pathlib.
This python script will get all bookmarks from Edge browser:
import json
from pathlib import Path

bookmark_path = Path.home() / "AppData/Local/Microsoft/Edge/User Data/Default/Bookmarks"

with open(bookmark_path, "r", encoding="utf-8") as f:
    data = json.load(f)

# Exemplu: listăm toate titlurile bookmark-urilor
def extract_bookmarks(bookmark_node):
    bookmarks = []
    if "children" in bookmark_node:
        for child in bookmark_node["children"]:
            bookmarks.extend(extract_bookmarks(child))
    elif bookmark_node.get("type") == "url":
        bookmarks.append((bookmark_node["name"], bookmark_node["url"]))
    return bookmarks

all_bookmarks = extract_bookmarks(data["roots"]["bookmark_bar"])
for name, url in all_bookmarks:
    print(f"{name}: {url}")

Python 3.13.0rc1 : Testing python with Ollama local install.

I was very busy with development and testing for about two weeks and my laptop was stuck and I was working hard... Today I managed to test local background clipping on my laptop with a local Ollama installation separated by a Python module but with processing from the Python script. I also used Microsoft's Copilot artificial intelligence for python and it works well even though it is not theoretically specialized in development. The source code is quite large but the result is very good and fast:
import subprocess
import os
import json
from PIL import Image, ImageOps

class OllamaProcessor:
    def __init__(self, config_file):
        self.config_file = config_file
        self.model_methods = self.load_config()

    def load_config(self):
        try:
            with open(self.config_file, 'r') as file:
                config = json.load(file)
            print("Configuration loaded successfully.")
            return config
        except FileNotFoundError:
            print(f"Configuration file {self.config_file} not found.")
            raise
        except json.JSONDecodeError:
            print(f"Error decoding JSON from the configuration file {self.config_file}.")
            raise

    def check_ollama(self):
        try:
            result = subprocess.run(["ollama", "--version"], capture_output=True, text=True, check=True)
            print("Ollama is installed. Version:", result.stdout)
        except subprocess.CalledProcessError as e:
            print("Ollama is not installed or not found in PATH. Ensure it's installed and accessible.")
            raise
... 
Here is the result obtained after finishing running in the command line:
python ollama_test_001.py
Configuration file ollama_config.json created successfully.
Configuration loaded successfully.
Ollama is installed. Version: ollama version is 0.5.7

Python 3.7.3 : Get location of International Space Station.

Today I tested the urllib python module with python 3.7.3 and json python module.
The issue was to get the location of International Space Station - Open Notify.
The International Space Station is moving at close to 28,000 km/h so its location changes really fast! Where is it right now?
This is an open source project to provide a simple programming interface for some of NASA’s awesome data.
I do some of the work to take raw data and turn them into APIs related to space and spacecraft.
C:\Python373>python.exe
Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64 bit (AMD6
4)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib.request
>>> with urllib.request.urlopen('http://api.open-notify.org/iss-now.json') as f:
        print(f.read(300))
...
b'{"iss_position": {"longitude": "-86.9247", "latitude": "-38.3744"}, "message":
 "success", "timestamp": 1556575039}'
>>> with urllib.request.urlopen('http://api.open-notify.org/iss-now.json') as f:
...     source = f.read()
...     data = json.loads(source)
...
>>> print(data)
{'iss_position': {'longitude': '151.1941', 'latitude': '49.4702'}, 'message': 's
uccess', 'timestamp': 1556578621}
>>> print(data['iss_position']['longitude'])
151.1941
>>> print(data['iss_position']['latitude'])
49.4702
>>> print(data['message'])
success

Python 2.7 : Python geocoding without key.

Today I will come with a simple example about geocoding.
I used JSON and requests python modules and python version 2.7.
About geocoding I use this service provide by datasciencetoolkit.
You can use this service free and you don't need to register to get a key.
Let's see the python script:
import requests
import json

url = u'http://www.datasciencetoolkit.org/maps/api/geocode/json'
par = {
    u'sensor': False,
    u'address': u'London'
}

my = requests.get(
    url,
    par
)
json_out = json.loads(my.text)

if json_out['status'] == 'OK':
    print([r['geometry']['location'] for r in json_out['results']])
I run this script and I test with google map to see if this works well.
This is output and working well with the geocoding service:
