I am trying to choose an IDE for Python. I like IronPython and want to inquire if the code written in IronPython can run in a normal Python shell like IDLE
Most Python code should work cross-platform, cross-IDE as at heart they all use the same interpreter (although versions may differ). Your IDE should only edit and run programs and will not affect the code you write.

I am looking for some pieces of advices in order to accomplish a tiny task regarding Python. If someone would ask to provide a pic of a 'started interactive session of Python with your favorite editor with a Python script', what would you show to this person? Should it be a void script? How do you interpreter 'started interactive session'? How about your own favorite editor (I mean that you would suggest for Windows 10)?
Sorry for the triviality of my question,but I have just started with beginners' Python course
Just to make sure I am on the right way, if I have to submit to someone else a started interactive session and your favourite editor with a Python script, will be it sufficient to show the following windows as in the picture?
If you want to do interactive things, you probably just want to use jupyter notebook: https://jupyter.org/install#jupyter-notebook
You can always just type python at your terminal prompt if you have python installed, this will start an interactive session in your terminal, but jupyter is definitely easier to use once you get it set up.
Edit: regarding favourite editor, this is very much opinionated but I love sublime text. https://www.sublimetext.com/
Note that you probably would use one or the other: you would use a text editor to write scripts that could be run in a terminal, for example
# hello_world.py
print("Hello, world!")
then in your terminal
python hello_world.py
whilst you would use a jupyter notebook for example for quick experimentation or for demonstrating usage of your software to others.
In terms of interactivity, you should really check out Jupyter Notebooks. It's industry standard for a lot of tasks, widely used and with great performance and support. Also, Jupyter has an in-built code editor than can be run via localhost in your browser.
However, for a code editor, I will never stop recommending VSCode. Huge game changer, light-weighted and with support for pretty much any language. Jupyter notebooks can be run directly from VSCode, and the latest features that Microsoft introduced in this regard make using Jupyter inside VSCode really easy and intuitive. Also, extensions are a positive point as well.
If you're only planning on programming with Python, maybe checking out PyCharm is also a good idea, but I have working mainly in Python for the past 3 years and I have never missed anything on VSCode, even though I've tried PyCharm several times.
The simplest answer: go with the IDLE IDE, it comes bundled with Python by default. It starts with an interactive session, so you just type at the prompt (>>>):
print ("Hello, world!")
and your task is done, if it prints out your "Hello, world!" line.
In general, you start your python interactive session (python REPL, python terminal, python console, there are several terms for the same thing) and, since it's an interpreted language, everything you type in, Python will interpret and execute, if valid. Nevertheless, except for atomic examples, you'll want to use a code editor or IDE.
As a beginner, I'd avoid jupyter for the time being, it could get cumbersome. Stick with the default IDLE editor (you open a new file and type away) until you feel confident, then make the switch toward some editor or IDE that you fancy - Visual Studio Code is popular and has python debugger, vim is old as Bible, can run on a calculator, but it's a modal editor, best used with touch typing, Notepad++ is also good for coding...
I'd like to iteratively write and test my python code in the Python console. I can't find a way to easily load what i've got written in the editor (somefile.py) into the Python console in Pycharm. Is there a trick to doing so?
Pycharm will let me run the entire script but that's not useful because i want to build up my state in the shell by experimenting with the functions and data i've got in the environment (kind of like how a lisp programmer would use a REPL).
Pycharm have this alt-shift-E option.
This way you can write in the editor, select the lines you want to run and run them by alt-shift-E.
I use it all the time, although I find a lot of people not fameliar with this option.
I'm a very unexperienced programmer who has just began studying Python. I managed to do some basic stuff and now I tried packing my .py files to .exe files that can be shared with friends who don't have Python installed. I'm using python 3.4 so I was forced to use cx_Freeze which is pretty easy to understand, but I have a question: is there a way to "embed" a different console than cmd.exe in those .exe's?
I wrote some scripts that work only with command line, but window's console is pretty ugly and frustrating. I want my packed .exe to be opened with a more friendly console (even something like IDLE), is that possible? (everything must be packed in the final .exe, because this have to work even on an external pc that doesn't have python installed or a specific console installed).
Sorry for my bad english!
May be you should look to "py2exe" which is only build for windows.
I'm not sure at all you can embed "idle" in you "compiled" python project. If you need a more windows friendly presentation, I suggest you use wx python library which can be easily embed in your py2exe project.
see http://sourceforge.net/projects/py2exe/ and http://wiki.wxpython.org/py2exe
in Sublime console one can execute arbitrary python code. But how can I select the current file buffer to execute commands on it? Like in a "on the fly" plugin.
EDIT
I wasn't clear in my question. I don't want to execute the Python code I'm programming, and I'm aware of SublimeREPL. I want to manipulate the text I'm writing (being it code or not) with Python, perhaps using Sublime API, to search, replace, manipulate text and so on just like you would do in a Sublime plugin, but one-off, just like you'd do with Elisp in Emacs.
Your best bet is to use SublimeREPL, also available through Package Control. The ST2 console just runs the internal Python version 2.6, and you can't use any third-party modules. SublimeREPL runs any Python interpreter you have installed on your machine, and basically acts just like the command-line version. It utilizes the full syntax highlighting and completion capabilities of ST2, and allows you to transfer bits or whole files of code to the REPL.
I've been trying to find this information online but I'm not getting the answer.
I've used RStudio and Geany for editing files before. Now I'm trying to use ViM to edit python and R files (I know there's RPy, but nothing to do with my problem).
I would like to know how can I have 3 terminals (could also be vim buffers, or screen windows) with one running ViM and the others running R and Python. When I execute a Python script, the terminal (window or buffer) with python shows the output. The same when I run R scripts.
I would appreciate insight on this as this is something that's keeping me from using ViM regularly. I would also consider a solution with terminator terminal multiplexer or guake terminal. Any information about sending code for scripting from one instance to another is welcome.
Are you looking for a way to have a REPL inside Vim? If so, Vim wasn't really designed with that in mind, though there are some plugins that try. Conque is an example.
Some things I use to have a quicker code/run/test iteration with Python:
IPython's %edit feature, which starts editing a script with $EDITOR and will run the script after you exit.
vim-ipython which can send/execute/recieve code via an IPython interpreter.
tmux which allows you to have multiple shells side by side, but with little interaction between them.
Vim-slime is a general-purpose solution to this I'm pretty happy about, it will send blocks of code to any tmux pane, meaning it works for any language.

Your requirements for online information may not have been spelled out in enough detail, since I seem to find a wealth of information on using ViM as an IDE for both R and Python:

Have a look at vim-ipython, a plug-in for Vim.
You need to download the source (linked above), and run the Vim command :source path/to/file/ipy.vim.
Start by running a new IPython session (e.g. using IPython qtconsole or IPython notebook) and then type :IPython into Vim. Your Vim is now connected to the IPython instance you just opened.
You can press F5 to run the whole python script in your Vim, or Ctrl+s to run the current line. Ctrl+s will also run whatever is selected if you're in visual (i.e. 'select') mode.
