Not many people have contributed to this discussion although argubly I think this is just as, if not more important than the editor discussion. Working on my own projects is fairly straight forward as I usually develop on Linux (which is much easier platform for Python development than say Windows), my computer is not restricted in anyway and I always have an internet connection (at least during the development and setup). However when I have worked with schools then it's not been possible to install additional packages as the machines are locked down, or because they are not allowed to connect to the network. So I think this is an important step forward in making it easier to learn programming in Python. I have found on some of my own projects I have had to list a large number of steps required in installing the pre-requisites that an educational bundle will help with. I think it's good to start with the requirements rather than solutions. From the "must have" list, and my understanding, I was expecting just a list of modules that could be pre-built and easy installed, but the highly desired list goes beyond that. I think there could be a real benefit with those addditional features, although I'm not sure how easily they can be implemented on computers that are "locked down". One thing I do think we need to consider is how updates to the education bundle can be managed as no doubt there will be additional modules that need to be added in future such as when the next super-dooper Raspberry Pi hat comes out :-) I think it's worth highlighting some of the issues / difficulties on the different platforms, I've listed some of my experiences below. **Windows** It is harder to install python moduels (and software in general) on Windows as it may be neccessary to install using different sources (eg. binary install files as well as PIP). I think the biggest problem with Windows is likely to be that they are locked down to prevent software from being installed (including locking out the teachers in some cases). I think that having a single installable package which includes the most popular modules that are used in education would make it easier to give that as a single install step that can be applied to existing Windows systems. It could then be presented to the adminstrator as a single install client that can be pushed out on the system. **Linux (excluding Raspberry Pi)** Although (excluding the Raspberry Pi) Linux is used less in schools than the other platforms I think it's still useful to at least look at how the education bundle can be implemented on Linux. I think this could be useful for colleges and schools looking to re-use some older machines. I think we are likely to see this considered more in future as teachers become more adept with Linux based on experience with the Raspberry Pi. The current PIP system is designed to make it easier to install software, but it's not quite as straight forward as it should be. It can be an issue where a computer is locked down to prevent additional software being installed and support for all packages isn't as easy as it could be. For example to install pygame for Python 3 on Ubuntu requires compiling the package and if using PyUSB (to control a USB device) then that includes dependencies upon Libusb and the package needs to be manually downloaded and installed using setup.py. **Raspbian on Raspberry Pi** Raspbian is already further ahead than some other Linux distributions with inclusion of pygame for Python 3, although it still has difficulty with some other packages (such as PyUSB). In some schools the Raspberry Pis are all being used off-network (due to school policy), so I think it would be good to get additional packages installed in the NOOBS image so they are available by default. **Mac OSX** Unfortunately I don't have any experience with Mac to be able to comment on the particular issues, although I expect it will not be too different from the other platforms in terms of issues. -- Stewart Watkiss @stewartwatkiss @penguintutor http://www.penguintutor.com

Lots of great discussion but I'm losing track of our list, so I've moved it to a google doc. Please suggest amendments so that we can get a final list together to vote on before we turn to finding volunteers to help build it. Then we will take it to a testing phase to get feedback from real learners! https://docs.google.com/document/d/1rXM2-Up59PbOEXqZHbo_jj-zPFkhc---kVVMinP… Thanks, Carrie Anne.

Common feedback from people trying to use Python in education is that it can be difficult and confusing to get a system that includes all the dependencies they require. Although the Python standard library is ‘batteries included’, we commonly want to use libraries like the Python Imaging Library, PyGame(Zero), NumPy and more. These are often non-trivial to install, particularly on Windows. The aim is to produce an easy to install Python ‘education’ bundle that includes many of these dependencies. A non-goal is replacing the existing Python installer package. As a number of people have pointed out, Conda (http://conda.pydata.org/docs/) might be a sensible starting point for this. I think it would be most sensible to start by more clearly working out our requirements before we get in to a detailed discussion of existing technical solutions though. To kick things off, here’s a list of possible requirements brainstormed by Alex Bradbury and I. Please do suggest things we may have missed. *Absolutely must have*: - Package available for Windows, Mac, and (ideally) Linux - Includes common libraries like PyGame and NumPy - Users still have the ability to install simple new libraries via pip install or similar - Include a graphical editor, ideally the new editor this working group is pursuing *Highly desired*: - Ability to select pre-built versions of libraries that weren’t picked for inclusion in the standard package after installation - Ability to easily Python and package versions after installation - Some way of helping the user make sure they’re running the ‘correct’ python/pip - Thought given to common Windows network management solutions used by schools To keep track of this list I've created another google doc that we can work on here <https://docs.google.com/document/d/1XZS-piBFsoKbZwnoZZZbmypxMXhz4U0pa0NCZFp…> .

A new, kid-friendly Python editor

Hi, I would like to initiate work on building an education friendly python editor to potentially replace IDLE and be part of an education bundle available across multiple platforms (including relatively low-specced systems such as the Raspberry Pi) through this work group. To kick off, here’s a list of possible requirements. Please feel free to comment and add to them: *Absolutely must have*: - Both windows open within one application (the shell window and text editor window). - Simple buttons to run code - A way to change font sizes easily - Syntax highlighting *Highly desired*: - Error reporting that highlights lines and gives a good level of feedback to the user. - REPL - Projects Since my talk around the development of a new text editor at Euro Python <https://youtu.be/_gU7sfTrz4c> in July and Pycon Australia in August, community members Ntoll (Nicholas Tollervey), Lord Mauve (Daniel Pope), and others have begun work on an open source project called Puppy <https://github.com/lordmauve/puppy>. Here is a video <https://www.youtube.com/watch?v=PXfzfZzq1dc> of Puppy but I believe that more has been added and/or removed since it was filmed. I think this project could be what we are looking for and we would welcome the thoughts of the wg. Thanks, Carrie Anne

HI! Great discussion. The already tab-enabled IDE I'd suggest is Geany ( http://www.geany.org/Main/HomePage), which is free and lightweight enough to work fine on the Pi. In fact I was introduced to it by the folks working on Pi3D, a package that lets you do 3D graphics on the Pi in Python.

This would be particularly useful when running on the Raspberry Pi as when I've seen Raspberry Pis used in schools they have often been off the school network. I like the 3 pane view used in Sonic Pi, although for Python I think the command line should be more prominent and use the width of the editor. So I think it should be Top Left (most of screen) editor, bottom left (width of editor) command line / messages, right hand side help. Context sensative help (hover / tooltips) would be good too, but I think that would be a nice to have rather than essential. -- Stewart Watkiss @stewartwatkiss @penguintutor http://www.penguintutor.com

Re: [Pythonedu-wg] A new, kid-friendly Python editor - big buttons / other features
by stewart＠penguintutor.com 22 Sep '15

22 Sep '15

Here are my thoughts – I’ve trimmed some of the quotes to reduce the size of the email (although it’s still very long). >> “I am afraid that I am not convinced that Puppy is heading in the >> right direction though. Has anyone asked kids what they want - perhaps >> at the recent UK Pycon? It might be that I am simply out of synch with >> the group (if so I will just back out politely and wish you all good >> luck) but I do not see there being a very large group of students >> around the world that want a really paired down editor with big icons: >> I don’t think there are many 8 year olds that actually could or should >> be learning Python. 10 and 11 year olds are already used to more >> sophisticated interfaces than Puppy” I think it’s difficult to ask someone that is just starting in programming what they need and they honestly don’t know. They wouldn’t be able to tell you what features they would like as they don’t know enough about what they will do. It is however possible to see when children are getting confused around the current interface and that provides a basis that can reduce the barriers to entering programming. The current interface of IDLE is confusing and does get in the way of them learning programming. It’s not just the children that struggle with this either, the parents do too. I spent a few minutes explaining the different windows to one parent at Pycon UK on Saturday who was unable to help their child as they were confused. Regarding the size of the buttons, I don’t think the buttons need to be particularly big, but what is needed is to limit the number of buttons and make it easy for them to know which button does what. For example there should be just one button for RUN and not have to know it’s Run Module rather than Run Shell. >> “Thinking student first though, we would realise that font size >> buttons are for the teacher not the students, therefore this facility >> should be included and made easy for teachers to implement but >> probably in a View menu and with sensible shortcut keys.” Font size is useful for several people. Clearly it makes it easier for the teacher when projecting on a screen, but it’s also useful for children with a visual impairment, or just to make it easier when pair programming. Being able to shrink the size is good when you start writing longer programs as it allows one to easily see the rest of the code to remember the variable name etc. >> “My students would want help with the indent problem, therefore I >> would add easily accessed indent, dedent and reformat (for pasted >> code) buttons and insist that there are only 4 spaces allowed, no >> choice. Personally I would prefer a simplified frame system which also >> gets rid of the long line of code problem; getting rid of this problem >> means that students can be encouraged to use meaningful variable names >> with out worrying about code clutter. They would also like help with >> avoiding syntax errors in the first place rather than having them >> pointed out at run time.” Indent is certainly one of the things that trips young (and old) programmers up, so a good consistent indent system is needed. I personally think spaces is better and would agree with that. Being able to select a chunk of code and move it to the next indent is very useful especially when copying and pasting sample code. >> “There are many other things I know my students would like to see (and >> that I would like to see for them) but, just out of interest, their >> number one priority would be a deploy/share menu so that they can >> share applications they make with their friends and relatives on any >> platform without having to ask them to install Python first. Probably >> the hardest thing to implement!” A good point, but potentially a conflict with Python itself. One of the benefits of an interpreted language is that the code is portable and compiling to a binary would go against that. It may make it easier to run on Windows, but then stops it working on other systems. Or you end up bundling the Python interpreter with the code which turns into a huge wasteful package. Perhaps if there was a python-lite that was just a python installer that installs Python from the web that would be a compromise, but personally I’d prefer a README file with a link to https://www.python.org/downloads/ I do think that compiling to micro:bit /codebug is a little different as that is coding for a very specific platform which has to be compiled and obviously that fits in with the educational aim. >> “I would like to see a more ambitious IDE developed.” I would also like to see a more ambitious IDE for Python, but I don’t think that would meet the aims of this list which is focussed on making it easier for those new to programming. Something that goes beyond what IDLE does but not as complex as Eclipse would be great for those looking to progress upwards from the kids editor, and useful for professional programmers, but beyond the scope of this group. >> “Really sorry if I have offended anyone. (I know some people have >> already put in a lot of work.)” I’ve not been involved in the development work, but I don’t think your email should have offended anyone. I do think you raise some good points, I think there are many that would prefer a more advanced editor. Personally I think that the current suggestions are good and have a realistic chance of being implemented within a reasonable time. >> “I think my problem comes down to this: Is this group going to be >> focussed on producing only what can be done by a group of enthusiastic >> but time-limited enthusiasts or is it able to, within a year say, >> create something that is as professionally produced for students as >> the many commercial tools available to developers?” I don’t think it’s about commercial funding vs volunteer effort. There are a huge number of open source projects that have never had any commercial funding, but are every bit as professional as commercial software. Many of the tools I use for development are based upon open source non-commercial software. -- Stewart Watkiss @stewartwatkiss @penguintutor http://www.penguintutor.com

Welcome to the PSF Education Working Group
by Carrie Anne Philbin 21 Sep '15

21 Sep '15

Hello, Thank you for joining the mailing list for the PSF Education Working Group <https://wiki.python.org/psf/PythonEduWG>. Python in education is a topic close to many of our hearts and this working group has been formed to make things happen in a number of ways: - We're a meeting point for people who want to make practical contributions to Python in education. - We identify and coordinate projects that deliver specific and measurable results that support our aims. - We support and facilitate such projects so they have the best chance of meeting their goals. In particular we will be focusing on: - Education friendly editor (IDLE) - An educational Python bundle available across platforms - Lessons and resources - A way to communicate, coordinate, and facilitate the educational events that are happening around the world. I’ll be sending out emails to start discussion on the first two topics shortly. Please do ensure that you take a look at the working group charter here <https://wiki.python.org/psf/PythonEduWGCharter>so that in the not too distant future, we can start a discussion around governance. We need to elect a chair and co-chair to provide reports to the PSF board. I’m happy to fill this role in the interim period. Finally a polite reminder that this is a group for making things happen. Long off-topic discussions will be bumped, in some cases to the education sig where they can continue. Many thanks, Carrie Anne Philbin
