> No it is not the proper way of a school test to copy what others provided. You're right but I need just to understand what tools I should use, it could be nice if the teacher says something like "use just these three tools to solve this problem" or "you don't need to use these other tools to do it!" I hope you understood what I mean... ^Bart

I thought to use (text) - (space), space is " " but I should replace in text what I said in the variable is space. I know there are a lot o solutions but this afternoon I'll ask to the teacher what we should do to do it! Thank you very much for your reply! :) ^Bart

EPS: Announcing the Guido van Rossum Core Developer Grant
by M.-A. Lemburg Jan. 31, 2019

Jan. 31, 2019

At the last General Assembly of the EuroPython Society (EPS) at EuroPython 2018 in Edinburgh, we voted on a new grant program we want to put in place for future EuroPython conferences. We all love Python and this is one of the main reasons we are putting on EuroPython year after year, serving the "cast of thousands" which support Python. But we also believe it is important to give something back to the main team of developers who have contributed lots of their time and energy to make Python happen: the Python Core Developers. This group is small, works countless hours, often in their free time and often close to burnout due to not enough new core developers joining the team. Free Tickets for Python Core Developers --------------------------------------- To help with growing the team, putting it more into the spotlight and give them a place to meet, demonstrate their work and a stage to invite new developers, we decided to give Python Core Developers free entry to future EuroPython conferences, starting with EuroPython 2019 in Basel, Switzerland In recognition of Guido’s almost 20 years of leading this team, and with his permission, we have named the grant “Guido van Rossum Core Developer Grant”. Details of the grant program are available on our core grant page: https://www.europython-society.org/core-grant PS: If you are a core developer and want to organize a workshop, language summit or similar event at EuroPython 2019, please get in touch with our program workgroup (program(a)europython.eu) soon, so that we can arrange rooms, slots, etc. PPS: If you want to become a core developer, please have a look at the Python Dev Guide: https://devguide.python.org/coredev/ Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you ! Link to the blog post: https://www.europython-society.org/post/182445627020/announcing-the-guido-v… Tweet: https://twitter.com/europythons/status/1090901995635073024 Enjoy, -- EuroPython Society https://ep2019.europython.eu/ https://www.europython-society.org/

I am by any means not Python expert but I do have a basic Python knowledge and I do occasionally use Pyhon to perform some tasks. I am not a professional programmer but rather an electrical engineer and I am using various programming languages since 1982. I started with Z80 and 6502 assembler, Fortran, Pascal, ... and since I am often using microcontrollers my main programming languages are C and assembler. However, sometimes when I have to process some data, parse some file, generate some data, extract of filter some results acquired by sampling or measuring analog values, ... I do use Python - although I never learnt it from the book. I am using Python as a tool to accomplish the tasks as they 'arrive' and although my code is for sure not written in Pythonic way - it works. Since arrival of various SoCs (e.g. Rasbperry Pi) I used Python not only for pre/post processing the data but for building applications as well and some of the Python programs I wrote are: - Driver for *very* fast 3D printer which is unique in its construction - Filtering the data acquired from multiple AD converters sampling movements of human body using Savitzky-Golay filter - Program for sending large amount of data in real time via I2C BUS towards multiple microcontrollers every 10 ms (I used threading and Queue from multiprocessing and I am, upon sending the data over I2C BUS, scheduling a new thread in a way timing disturbances caused by background tasks and interrupts don't accumulate over time) - Programs used as 'a glue' between node.js code and microcontrollers - Interpolating the data used for sinhronizing lip movements of humanoid robot with spoken words between the keyframes - 3D animation of humaniod robot arms based on the data acquired by motion capture and by recording movements using rotary encoders And yes, I did use OOP. For example, I can use my driver for 3D printer to print one layer as follows: from Printer3D import Head import numpy as np import cv2 import glob import time np.set_printoptions(threshold=np.nan) layer = cv2.imread("./png_input/layer.png") visina, sirina = layer.shape[:2] print visina, sirina layer = cv2.cvtColor(layer, cv2.COLOR_BGR2GRAY) #layer = cv2.resize(layer, None, fx=0.5, fy=0.5, interpolation = cv2.INTER_AREA) hd = Head(layer) hd.setSteps_x(44, 44, 382) hd.setDistance(21) hd.setHead_GPIO([0, 4, 17, 27, 22, 10, 9, 11, 5, 6]) hd.setMotor_GPIO([13, 19, 26, 21, 20, 16]) hd.move(Head.ROW_UP, 10) hd.printLayer() hd.move(Head.UP, 10) So, the truth is - I am indeed (obviously) not familiar with everything you mentioned but you can decide for yourself if everything I already did using Python could be classified as 'not much'. -- Let There Be Light Custom LED driveri prema specifikacijama http://tinyurl.com/customleddriver Chupo

what considerations for changing height of replacement radiator?
by jkn Jan. 31, 2019

Jan. 31, 2019

Hi all I'm looking at changing a radiator in a bedroom shortly and wondering about my options re. sizing. The current radiator is 900mm W x 600mm H, and is single panel, no convector. So looking at some representative specs, let's say 550W output. I would be replacing this with a single panel, single convector radiator. From looking at the spec again, the same sized radiator gives around 50% greater output - 900W. I am wondering about fitting a 900mm W x 450mm H single panel, single convector, which would then reduce the output again to 700W or so, similar to the original. My reason for doing this would simply be 'neater appearance' of the smaller radiator, but it wouldn't be a problem if the replacement was the same size as the original. I am wondering if there is anything else (apart from power output) that I should be considering here? The radiator will be under a window and the CH is an olde school 'plan C', I think. I would probably fit a TRV in any case. There is no need to heat the room any better than currently... Thanks for any advice. Cheers Jon N
