I've just started using PyCharm, and am consistently pleasantly surprised by its tools and configurability. I know that in PyCharm, you can load code from the editor into a Python console (see https://www.jetbrains.com/pycharm/webhelp/loading-code-from-editor-into-console.html). However, the remote console I'm using in PyCharm is very slow.
If I access python on the remote machine directly via ssh, it has no performance issues. As such, I'd like to just open the remote version of python via PyCharm's Terminal, and execute code in the terminal from my editor.
However, I haven't found any key bindings (or options) that let me automatically load code -- it's a manual copy and past process for now. When I try to create a keyboard shortcut to do this, the option isn't available. Is there a method to create a keyboard shortcut to load code from the editor into the terminal?
The only way to create such a shortcut by yourself is by writing a plugin to PyCharm. PyCharm plugins are written in Java, so I don't know whether this sounds like an appealing option for you. Alternatively, you can file a feature request at http://youtrack.jetbrains.com/ asking for this feature to be added.
Note that you can set up a run configuration that will run your code for you on a remote interpreter without going through a console. Have you tried this? Is it also slow?

I've scoured the interwebs and couldn't find anything with python, android, and "shortcut" or "home-screen" to appear on the same page. I have pydroid3 installed, working great. I'd like to have a shortcut (ideally on the home-screen) that I can tap once and have it run without opening the IDE for editing.
Making a shortcut to the file, or opening a source file in the file manager will at best just open it in the pydroid3 IDE, at worst state "this file type is not supported."
At the beginning of the script, I have tried putting "#!/user/data/../pydroid_dir/python", but alas the OS doesn't realize I mean to run it directly in the python interpreter. Any solutions or alternative lines of thinking are appreciated!
EDIT
I'm running an unrooted android 9 PIE. I wanted to provide some more details but not quite a solution for any readers. Check out related question: How to create a homescreen shortcut to launch a shell script?. Closest I got was trying SManager which allows you to create a homescreen shortcut to a shell script. Your shell script could be hardcoded to call python on your script:
/path/to/python /path/to/python/script
Unfortunately, if you're phone is not rooted, you may not have permission to execute whatever version of python you're calling outside of the context of the app it was installed for. Also, you have to ensure that your shell and python scripts reside in an appropriate place for execution. If your phone is rooted, SManager seems to have options to let you run the script as root.
pydroid3 allows me to run scripts residing on my internal storage as well as lets them read and write files at that location. That's why I was hoping that there was a pydroid way to create a shortcut (or an alternative python app that does this) since it has appropriate privileges.
QPython OL lets you create home screen shortcuts to python scripts on Android. First tap on the 'Q' icon at the top of the main screen (it took me a while to realise this was a button), then long-press on the script you want. This should give you a prompt to create a shortcut, as in the screenshots below.
QPython 3L also claims to have similar functionality when you long-press a script in its 'Programs' section. At time of writing (Jun 20) this seems to be broken.
I've not tried Pydroid myself, but haven't come across anything claiming it could create script shortcuts either.
You can use Termux:Widget as a command line to execute a python script. In Termux you can not create GUI with tkinter. You have to launch X-Server with VNC Mobile client. The widget is like a small shell prompt.
I initially started learning Python in Spyder, but decided to switch to PyCharm recently, hence I'm learning PyCharm with a Spyder-like mentality.
I'm interested in running a file in the Python console, but every time I rerun this file, it will run under a newly opened Python console. This can become annoying after a while, as there will be multiple Python consoles open which basically all do the same thing but with slight variations.
I would prefer to just have one single Python console and run an entire file within that single console. Would anybody know how to change this? Perhaps the mindset I'm using isn't very PyCharmic?
There is a specific option in PyCharm 2018.2+: Settings | Build, Execution, Deployment | Console | Use existing console for "Run with Python console".
Run with Python console is an option you have enabled in the Run Configuration. Disable it if you don't need a Python console after a script execution:
Hi: If you are looking for re running the code again in the same python console everytime then you have to check the respective box in the Project settings as shown in image below.
To allow only one instance to run, go to "Run" in the top bar, then "Edit Configurations...". Finally, check "Single instance only" at the right side. This will run only one instance and restart every time you run.
One console is one instance of Python being run on your system. If you want to run different variations of code within the same Python kernel, you can highlight the code you want to run and then choose the run option (Alt+Shift+F10 default).
You have an option to Rerun the program.
Simply open and navigate to currently running app with:
Alt+4 (Windows)
⌘+4 (Mac)
And then rerun it with:
Ctrl+R (Windows)
⌘+R (Mac)
Another option:
Show actions popup:
Ctrl+Shift+A (Windows)
⇧+⌘+A (Mac)
And type Rerun ..., IDE then hint you with desired action, and call it.
I think that what you are looking for is the last option in this window; check it and it should work.
Settings -> Build, Execution, Deployment -> Console
I have been writing scripts in Python console provided in Pycharm but now I need to save them on my desktop and run them at some later point. I can not happen to find any option to do so for the console scripts.
I don't think there is a way to save the contents of a console session within PyCharm (or any other editor that I know of). As #daladier pointed out in the comments, though, iPython may be what you are looking for. Using Jupyter Notebooks which are based on iPython you can create interactive cells in notebooks that behave similar to the console.
I am trying to use Curses in PyDev in Eclipse in Win7.
I have installed Python 3.2 (64bit) and curses-2.2.win-amd64-py3.2. When I input the following testing codes into PyDev:
import curses
myscreen = curses.initscr()
myscreen.border(0)
myscreen.addstr(12, 25, "Python curses in action!")
myscreen.refresh()
myscreen.getch()
curses.endwin()
It did not show any syntax error, so I think the curses was installed correctly.
However, when I ran it as Python Run, the output showed: Redirection is not supported. I do not know where this problem comes from. I googled a lot but can't find related information.
Recent PyCharm versions (I am currently running 2017.2, not sure when this option was added, or if it has been there the entire time) have the option "Emulate terminal in output console". Curses works with this option checked.
You cannot expect to use curses with a non-terminal.
Probably you get this because you are running the script from inside an IDE, like PyCharm or any other.
All IDEs do provide consoles that are not terminals, so that's where the problem comes from.
For a Pycharm user the solution given by codeape works fine :
Snapshot
You can't use any IDE to run python files with the curses package. I used to run in pycharm and naturally couldn't run.
Change to the command line to run:
for testing follow my following steps
on desktop open notepad and copy paste the code and save it as filename.py
open command line change directory to desktop use below command cd Desktop and hit enter type python example.py and hit enter, your program will definitely run
My workaround is to create a Run Configuration that calls a curses script. The little overhead is worth not having to switch to the terminal and manually run the script hundreds of times a session. I use Intellij but I imagine the process should be similar in PyCharm.
The desired result is the convenience of a button to run the script:
First create a script that calls the entry script, for instance:
ptyhon name-of-script.py
Then, to create a configuration for each script:
Go to Edit configuration.
Click the plus button and add a Shell Script.
Enter the path to a shell script.
Here is a picture of a directory with a couple of sample scripts.
I use this process to view my progress. My curses scripts are very modest so fortunately I can live without a debugger.
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.
