At first, I'm not good at English but I'm doing my best, thank you.
I connected Amazon Lightsail and installed python36.
It is the list I installed.
python36.x86_64
python36-devel.x86_64
python36-libs.x86_64
python36-pip.noarch
Then I entered shell as shown in picture below after typing 'python3'.
At https://realpython.com/python-idle/#what-is-python-idle, How to Use the Python IDLE Shell's first image, it looks very similar to the image I uploaded.
So I think it is Python IDLE but I'm not sure yet.
Because at https://www.centos.org/forums/viewtopic.php?t=53908, 'python34-tools' contains idle3.
What? I'm not installed 'python36-tools'!
I installed 'python36-tools' and typed 'idle3' but there's an error, 'command not found'.
Even according to https://centos.pkgs.org/7/puias-unsupported-x86_64/python36-idle-3.6.6-1.sdl7.x86_64.rpm.html, it is definitely Python IDLE!
What's the right thing? I'm so confused.
I wanted to know more, so visit https://docs.python.org/ko/3.6/whatsnew/3.6.html and find this, 'The IDLE features formerly implemented as extensions have been reimplemented as normal features.'
It can be translated like this?
'Starting with version 3.6.3, you don't have to install idle3 separately. Just type python3 for use Python IDLE.'
I searched the information related to the above and couldn't find anything.
Please help me!
IDLE is a GUI application, with menus and windows. So you need to use a Linux/macos/windows desktop environment, it does not run in a terminal window.
It actually looks like this: https://www.youtube.com/watch?v=bOvqYw1SZJg
It starts in a standard python interactive shell, such as your screen shot.
But being a desktop app, it allows you to have multiple editor windows open with source files, and it has GUI debugging tools. IDLE is rudimentary, but also very simple (which can be a good thing).
I think there is a lot to be said for learning python in a real desktop environment, with multiple windows and friendly, easy to use debuggers.
There are cloud IDEs for python, but I don't think they are a good step for newcomers. The debugging is not very good, for instance.
However, jupyter is a good option for learning python, I think.
E.g.: https://realpython.com/jupyter-notebook-introduction/
Jupyter runs a webserver and you edit python in interactive workbooks which you open in a browser. I suppose it is a cloud IDE.
This is a short video of running it on Windows ... https://www.youtube.com/watch?v=jZ952vChhuI
jump to about the 2m mark to see it running.
To be honest, it is arguably a better place to start than IDLE.You could run the server part of this from lightsail, but you will probably need to configure your lightsail instance to open the ports needed to server jupyter's web pages.
But if you want to start with IDLE, you need python running on a desktop. A linux desktop is a very good choice. You can set up a desktop linux, such as ubuntu, in virtualbox if all you have is Windows.
However, if after all of that, you are going to do python from the command line, you should learn about
* virtual environments
* once you set one up, do pip install ipythonto get a better version of the python shell.
As others said, python3 on a non-Windows command line starts python in interactive mode. To start IDLE on a command line, use python3 -m idlelib.

So I've written a program in Electron that will download the latest version of our image and then write it to the selected device.
I've got this working fine for Linux and OSX as I'm able to call a sub process and just run the dd command directly.
My issues come when trying to make this work on Windows, I've not been able to find a node package that does dd or something similar, and natively writing it for Windows doesn't want to work due to the chaining of commands etc.
Does anyone have any suggestions? My next idea would be to write a .bat script that is called by the sub process and try to do it that way. However if there is a platform universal approach with node that would be ideal! Thanks.
I wouldn't start rolling my own approach for this using Node.
Rufus is the current go-to app on Windows for burning images to various media. It has limited command line support – the author says you should try rufus -h to see what's possible.
There's also Etcher CLI, which is "experimental, proceed with caution and report issues". (Also, the Etcher GUI is actually an Electron app, so you might want to peek into what it's doing. https://github.com/resin-io/etcher)
Hope these help.
again a beginners question...I got a Python 3.5 script i want to run on a windows server. I found that thread and some links like this one but stil are not clear.
I got my sript on my laptop and I am importing some packages like boto3 from AWS. Now I want to execute on a windows server and also have an option to stop it.
My script has a thread that is running in an infinity loop until some break conditions occur.
How to package my "program" so I can run it on the server right away without using pip to install all the packages I imported?
Should I turn my thread into a deamon?
How to add a start/stop automatic? I think once Python is added to the path a doubleclick can start it or u are using a bat file to call it...but how to stop it?
Can someone outline the steps I need to perform?
Referring to your first question, I would recommend you to look into Docker. Docker is a containerization technology that makes it easier to run your software on any OS. It also "orchestrates" the installation of your dependencies by building an image so that you don't have to it manually every time. See https://runnable.com/docker/python/dockerize-your-python-application
I recently opened an account with PythonAnywhere and learnt it is an online IDE and web hosting service but as a beginner in python 3.4, what exactly can i do with it?
PythonAnywhere dev here,
You can use PythonAnywhere to do most of the things you can do on your own computer with Python
start a Python interactive console (from the "Consoles" tab)
edit a python file and run it (from the "Files" tab)
The exception is that, if you want to do things with graphics, like use pygame, that won't work on PythonAnywhere. But most text-based console things will work.
You can also do some more funky things, like host a web application ("Web"), and schedule tasks to run at regular intervals ("Schedule"). If you upgrade to a premium account, you can also run "Jupyter Notebooks", which are popular in the scientific commmunity.
If you need help with anything, drop us a line to support#pythonanywhere.com
Pythonanywhere is a cloud PAAS, what that means is you can just worry about coding and leave the headache of hosting, platform, DB and PAAS considerations on pythonanywhere. Anyone who has tried to deploy a website prior to the cloud days can attest to how many more things developers had to worry about
A good example to get started

I am new to python. So please pardon my mistakes/ignorance.
I have an GUI app script that I use to copy some folders from another machine to my machine and also do some other processing with the files in the folders.
Now, I would like to place this script on my machine and let other people(with no python installed on theirs machines) to execute this script. I want it to behave as if it was running on their machine. I mean, I don't want to see any errors while this script from my machine makes any changes to their files like access denied etc. It should tread D:\ drive as theirs not mine.
Is it possible somehow in python?
Thanks in advance.
I don't know the way do such a thing. But maybe you can use tools such as py2exe to convert Python scripts into Windows .exe applications.
And as the introduction
It is an utility based in Distutils that allows you to run applications written in Python on a Windows computer without requiring the user to install Python. It is an excellent option when you need to distribute a program to the end user as a standalone application. py2exe currently only works in Python 2.x.
if you use python3.0 or 3.1, this question is helpful.
I have been using a chrome book for a few months now. I also have been designing a web page. A lot of the work can be done via word press's lame gui, but like any coder, I want to use a real text editor, specifically vi/vim.
I have done some searching around. I found one java script implementation of vi, but it's not good enough IMO to use. Conversely, I'd like to ssh into one of my *nix boxes and use vi that way, although you cannot do that from web pages it seems. HTTP vs TCP issues. Not sure if WebSockets will be able to get around this.
Lastly, I've been looking at plugins. While some decent ones seem to be available for Firefox, the Chrome division is lacking severely.
One desparate try is vnc, but this chromebook has no javascrip support, not can I get the HTML5 vnc running quite right.
Does anyone have any suggestions?
Edit/Update:
Thanks for everyone's effort in answering. I quickly abandoned coding on the netbook, but it looks like some great answers were provided.
I am on a Samsung ARM Chromebook and I do a lot of development work in Vim. Here's how I prefer to do it:
Enable Developer Mode, then download crouton.
Open a shell:
<ctrl><alt>t
...and install Ubuntu command-line environment
sudo sh -e crouton -t cli-extra
Enter the chroot using
sudo enter-chroot
From inside the chroot install vim
sudo apt-get install vim
There are lots more instructions and examples on the crouton github page.
I prefer the command line only version because I can just have Ubuntu in another tab, and all the Chromebook keyboard shortcuts Just Work.
You have few options:
Cloud9, an IDE for JavaScript, Python, PHP, and Ruby. Cloud9 uses the HTML5 FileSystem capability and AppCache to sync files, so you can even code offline. It got some really nice features that I find myself using a lot: github integration, chat, the ability to work and do reviews on your code without any pain of ‘new/other’ tools.
Kodingen is an Online Development Environment including Code Editor, Cloud Hosting etc'. I haven’t play with it (yet) – but I’ve heard some friends that like it.
Codey - Easy to use code editor for HTML, PHP, CSS, JS. They are in Chrome web store.
Akshell - Server-side JavaScript development and hosting platform. They got some git integration built in their IDE.
I hope it helps.
For more, I've posted something about this Q few months ago: http://greenido.wordpress.com/2011/07/04/web-developers-and-the-new-chromebook/
There are web shells: this is the first one that came up with a search, but there are others. Be sure to use HTTPS and place it behind a authentication gateway. I can't vouch for how well they handle vim and it's interesting screen modes, but hopefully one of them might work.
How about SourceKit? Unforunately the bindings are closer to textmate, it has great highlighting and IMHO the text will be easier on the eyes than if you were looking at tiny shell font.
