Currently I am doing some debugging on a script but when I run it the second time I get a false outcome. Now I want to restart the IPython console everytime when I run my script e.i. I want to include it in my script and do it automatically. I already tried to clear and restart my console but that doesn’t work. Has somebody an idea how I can solve this problem?
Thank you for your help!
Do you want to clear out all variables from previous run when you re-run the script? If yes, you can change the preference settings in Spyder.
Go to Tools > Preferences > Run > Check the box that says "Clear all variables before execution."

This appears every time I run a code from VS using zsh
The same happens even when I run it through the integrated terminal. This does not happen when I run the code in pycharm. How to fix this, please help.
Looks like you are debugging your code. The outputs maybe have related to the launch.json file. Could you create a new configuration and selected it to have a test again?
Or could you just right-click and select Run Python File in Terminal.
I tried to run a python program in VS Code. But my program didn't run. The terminal opened and a weird arrow was there in the terminal. This is the screenshot of that.
This is the weird arrow and the program is not running. Any ideas why this is happening and how to fix it?
Thanks in advance.
Firstly, the arrows are included in the default python IDE means that VScode ran the command to execute your code. Give your pc a restart. Now, let us check if python is working or not or VS code is having some trouble. Type the following command in cmd to execute the code-
python "$PATH"
Rember to replace $PATH to the path of the file i.e where your file is stored. For eg. I've my python files stored in D drive in a python folder, so I'll use-
python "D:\Python\Hello.py"
If this works, python is working fine and if not, try reinstalling python and check the box which says Add python to Path or Environment variables. Then open VS code try to run the program again. But click the button only once and be patient because clicking it multiple times causes execute the same command again and cause a problem. It's my personal experience. Wait 5 minutes. Not works. Don't worry, there's a problem with the run extension you are using. I'll recommend the Code runner by Jun han. I personally use it. Type this in the extension search box-
formulahendry.code-runner
Install it and then try again.
Kill the terminal, and retry. If not work, restart the VSCode.
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 just made the transition from Spyder to VScode for my python endeavours. Is there a way to run individual lines of code? That's how I used to do my on-the-spot debugging, but I can't find an option for it in VScode and really don't want to keep setting and removing breakpoints.
Thanks.
If you highlight some code, you can right-click or run the command, Run Selection/Line in Python Terminal.
We are also planning on implementing Ctrl-Enter to do the same thing and looking at Ctr-Enter executing the current line.
You can:
open a terminal at Terminal>New Terminal
Highlight the code you want to run
Hit Terminal>Run Selected Text
As for R you can hit CTRL Enter to execute the highlighted code. For python there's apparently no default shortcut (see below), but I am quite sure you can add yours.
In my ver of VSCode (1.25), shift+enter will run selection. Note that you will want to have your integrated terminal running python.
One way you can do it is through the Integrated Terminal. Here is the guide to open/use it: https://code.visualstudio.com/docs/editor/integrated-terminal
After that, type python3 or python since it is depending on what version you are using. Then, copy and paste the fraction of code you want to run into the terminal. It now has the same functionality as the console in Spyder. Hope this helps.
I'm still trying to figure out how to make vscode do what I need (interactive python plots), but I can offer a more complete answer to the question at hand than what has been given so far:
1- Evaluate current selection in debug terminal is an option that is not enabled by default, so you may want to bind the 'editor.debug.action.selectionToRepl' action to whatever keyboard shortcut you choose (I'm using F9). As of today, there still appears to be no option to evaluate current line while debugging, only current selection.
2- Evaluate current line or selection in python terminal is enabled by default, but I'm on Windows where this isn't doing what I would expect - it evaluates in a new runtime, which does no good if you're trying to debug an existing runtime. So I can't say much about how useful this option is, or even if it is necessary since anytime you'd want to evaluate line-by-line, you'll be in debug mode anyway and sending to debug console as in 1 above. The Windows issue might have something to do with the settings.json entry
"terminal.integrated.inheritEnv": true,
not having an affect in Windows as of yet, per vscode documentation.
I can run my script once with each Python console ("Python 1, Python 2, etc"), but after running, the console is unusable - I can't run or type anything into the console and get a return. When I try run the script again I get a message -
"No Python console is currently selected to run GameLoop.py. Please select or open a new Python console and try again."
If I open a new console, I can run the script again. But the new console has no memory of the variables created in the script.
I don't think this problem occured the first 2 times using Spyder. My version is Spyder 2.3.8 and I am running Python 2.7.
My console settings are set to "Execute in current IPython or Python console", but changing this setting to "dedicated" doesn't help.
How can I a console to continue being usable after running a script?
I'm running a different version of Spyder & Python but was able to repro your issue. Make sure you always have an iPython console running, this will make sure you don't get this error. This will help even on re-opening spyder.
Go to uninstall programmes>click on pythonxx(xx is version)>repair>yes
after repair procedure completed,Idle works fine.
