Last night I worked a bit with python and tested on the online tool from Copernicus.

Copernicus is the European Union's Earth observation programme, which analyzes our planet and its environment for the benefit of all European citizens.

If you want to test it with python or another A.P>I. you need to create an user and a apassword.This is the source code I used with S:

from sentinelsat import SentinelAPI, read_geojson, geojson_to_wkt
from datetime import date
# Connect to the Sentinel API
api = SentinelAPI('___', '___', 'https://scihub.copernicus.eu/dhus')
#
api.download('___from_copernicus_website___')
# Search for Sentinel-2 images covering a specific area
footprint = geojson_to_wkt(read_geojson('area_of_interest.geojson'))

products = api.query(footprint,
                     date=('20211201', '20211205'),
                     platformname='Sentinel-1')
# convert to Pandas DataFrame
products_df = api.to_dataframe(products)
print(products_df)
# sort and limit to first 5 sorted products
products_df_sorted = products_df.sort_values(['link'], ascending=[True])
products_df_sorted = products_df_sorted.head(5)

# download sorted and reduced products
api.download_all(products_df_sorted.index)

You need a JSOn file to select the area of interest:

After I run this python script, the result is this:

News : Inkscape team hiring python developer.

For the Inkscape project and its users, interoperability with other software packages, both free and commercial, is of high importance. The PLC has decided to hire a developer for the equivalent of 1.5 months (part-time schedule available) to implement importing functionality of a file format for which Inkscape yet lacks proper support. An extension of the project to up to 3 months (with additional compensation) may be granted depending on the success of the first half ...

Python 3.8.16 : My colab tutorials - part 028.

Today I added a new example to my GitHub repo on colab with a simple example of how to search for images using Google's custom search A.P.I. You can find this example on my Github webpage example.

Python 3.10.2 : MoviePy - part 001.

MoviePy is a Python module for video editing, which can be used for basic operations (like cuts, concatenations, title insertions), video compositing (a.k.a. non-linear editing), video processing, or to create advanced effects. It can read and write the most common video formats, including GIF.

You can read more about this python package on this webpage.

I install this python package with the pip3 tool:

pip3 install MoviePy --user

I have an AVI file type created with the Blender 3D software, named anime_effect_001.avi, you can find it on my youtube channel.

I used this source code to convert it into an mp4 file type:

import moviepy.editor as moviepy
clip = moviepy.VideoFileClip("anime_effect_001.avi")
clip.write_videofile("MP4_anime_effect_001.mp4")

I run with this command:

python moviepy_001.py
Moviepy - Building video MP4_anime_effect_001.mp4.
Moviepy - Writing video MP4_anime_effect_001.mp4
...
Moviepy - Done !
Moviepy - video ready MP4_anime_effect_001.mp4

I play the MP4 file with the VLC video player and works great.

Python 3.10.2 : Suite for Computer-Assisted Music in Python known as SCAMP.

SCAMP is an computer-assisted composition framework in Python designed to act as a hub, flexibly connecting the composer-programmer to a wide variety of resources for playback and notation. SCAMP allows the user to manage the flow of musical time, play notes either using FluidSynth or via MIDI or OSC messages to an external synthesizer, and ultimately quantize and export the result to music notation in the form of MusicXML or Lilypond. Overall, the framework aims to address pervasive technical challenges while imposing as little as possible on the aesthetic choices of the composer-programmer.

See the official webpage.

Let's install with pip3 python tool in Windows O.S..

pip3 install --user scamp

I created a python script named music001_test001.py with this source code:

from scamp import *
import random

s = Session()

guitar = s.new_part("Guitar")

text = "this is a test text"

for char in text:
    if char == " ":
        wait(0.2)
    elif char.isalnum():
        for x in range (0,10):
            guitar.play_note(ord(char) - random.randrange(50, 75), random.randint(0,5), random.random()/5)
    else:
        wait(0.2)
        guitar.play_note(ord(char), 0.8, 0.06)
        wait(0.2)

The source code is easy to understand. I use random to play into for loop.

I play these with preset Jazz Guitar for Guitar.

I could say that the result is quite good for the random function.

In my internet searches, I also found a rather interesting PDF file about this Python module and other enhancements. You can find it here.

OpenAI knows how to write source code for Blender 3D.

I tested the new OpenAI chat from with this question:

Please write a 3d blender script in Python that moves a camera around an object 360 degrees facing it.

import bpy

# Set the object that the camera will orbit around
target_object = bpy.data.objects["MyObject"]

# Set the starting position for the camera
camera = bpy.data.objects["Camera"]
camera.location = (0, 0, 5)

# Set the number of degrees to rotate the camera around the object
degrees = 360

# Set the distance that the camera should be from the object
distance = 5

# Set the speed at which the camera should orbit
speed = 1

# Set the direction in which the camera should orbit (1 for clockwise, -1 for counter-clockwise)
direction = 1

# Calculate the number of frames needed for the camera to orbit
# around the object by the desired number of degrees
num_frames = degrees / speed

# Set the camera to track the object
bpy.ops.object.select_all(action="DESELECT")
camera.select_set(True)
bpy.context.view_layer.objects.active = camera
bpy.ops.object.track_set(type="TRACKTO")

# Animate the camera orbiting around the object
for frame in range(0, num_frames):
    # Set the current frame
    bpy.context.scene.frame_set(frame)

    # Calculate the new position for the camera based on its distance from the object
    x = distance * math.sin(math.radians(frame*speed*direction))
    y = distance * math.cos(math.radians(frame*speed*direction))
    camera.location = (x,y,0)

I tested with the latest version of Blender 3D and it works well with some small changes it can be improved.

This error for this script:

Python: Traceback (most recent call last):
...
TypeError: 'float' object cannot be interpreted as an integer

If you ask more than once you will get different source code and I encountered a network error.

I tried several times and the network error did not let me take the more complex and complete source code.
