I had Python version 2.7.17 already installed on my machine. Recently I started coding in Python and I installed VS Code to make things easier. However once I opened VSCode and ran a simple Python Hello World program, VSCode terminal gave a warning saying that
Python 2 support has ended at January 1, 2020
which means the support has already ended and suggested to install the latest Python version. So I heeded the warning and installed Python 3.8.5 on my Windows machine. The installation was completed without any issue. Afterward, when I tried the command python --version on VSCode terminal, it correctly gave the output python 2.7.17. However, when I tried the command python3 --version to check if it was correctly installed, the terminal gave no output.
Since I am a beginner and the support for Python 2 has already ended, I would like to work with Python3 from now on. However, I don't mind Python 2 staying in the machine.
Is this something should I worry about? Or should I uninstall Python 2 completely (When I checked Control Panel both versions are list under currently installed programs)?
According to your description, you can change pythonpath in vscode and still keep python2.
I assume you are using windows system and if not, please let me know. The following is the solution:
open cmd and type: where python. There should be two path, copy it which is about python3.8.5;
press Ctrl+, to open setting.json and add an entry for python.pythonPath manually inside your User Settings:
Now you can press Ctrl+Shift+P and find the option select interpreter. Click it you'll find a interpreter list. After selecting new interpreter, it is necessary to press Ctrl+Shift+` to open a new terminal for further development.
About more detailed information about pythonpath and interpreter you can refer to using python environments in vscode.
The version of Python used depends on your environment, and PATH variable.
I think you need to select the correct Python interpreter. At the bottom of your screen, there should be something that says the Python version number. If you click it, you can get a menu to select the interpreter.
Alternatively, you can hit control-shift-p, type "python interpreter", then click "select python interpreter" option.
Finally, you can alter the default Python interpreter used by changing the User settings in VS Code. Hit control-shift-p, type "open settings", and select Open Settings (JSON). Add a key to the JSON file called "python.pythonPath", so that you have a line that looks something like this:
"python.pythonPath": "full/path/to/the/python/executable/you/want/python.exe",
You might be able to get a hint as to the path to use or available isntallations of python if you type where python or which python (depending on terminal/ OS in use).
Then you can save those settings. Restart VS Code. Hopefully now the correct interpreter is selected by default.

I have a script that I need to run using a very specific python interpreter in my hard drive.
I am using vscode as the IDE and trying to select the python interpreter using the command palette.
However, since the concerned interpreter is not present, I manually search it.
However, even after that, it doesn't work as typing python in the terminal then opens the windows store for installing a python IDE. I also tried adding the interpreter's path to the environment variables but the problem still persists.
How do I solve this issue.
Thank You for the help.
The Python version you selected on VS Code only effects the editor. Right click to any file on the sidebar and select Open in Integrated Terminal. If your selected Python version is created with virtualenv it will activated and your python command works.
If not worked and you want a global Python version, you need to add Python path to your system variables to work python command. Check this:
https://geek-university.com/python/add-python-to-the-windows-path/
Btw I don't think your python.exe in FreeCad/bin directory is proper Python version
At the bottom left you can select the Python interpreter.
Here it shows you on -how to do that: Python Interpreter
Reason:
Your system environment path contains this: %USERPROFILE%\AppData\Local\Microsoft\WindowsApps.
Solution:
Open Window Search(Win) to find Manage app execution aliases. To turn off App Installer of python3 like this:
You can refer to this answer for more information.
The Command Prompt does not do anything when I use the Python command to execute a module. It does not even do anything when I use it at all; it just pretends that I did not do anything, and goes back to the current working directory. Attached is a screen shot for clarity.
Apparently, if you call python from Windows' Command Prompt (at least with my home computer), it will look for any python version installed using Windows Store, so if you just type python, it will open the Windows Store for you to install.
If you have Python installed, try to call full path to executable or try to add the path containing your Python executable (in my case, C:\Python38) to the system environment variable PATH:
Search for "Edit the system environment variables".
Click the Environment variables... button (in the Advanced tab)
Edit PATH and append ;C:\Python27 to the end (substitute your Python version)
Click OK and reopen cmd for change to take effect.
Update.
I simply uninstalled and reinstalled Python. Once I did that, the program works as it should in CMD.
If you have python already installed, you should just be able to type 'python' alone then press enter. It should then give you a space to execute python code. It could be simple fix, but if not it's still worth a shot.
When its the first time you're going to install python on Windows it shows you the option Add to path unchecked, so you just need to check that option and install python, you can uninstall python and installet again with the check, this fix the problem.
I just use the IDLE, it is the easiest way to run python scripts. Just open up IDLE and click on File < Open.. < and select your file. Then make any last minute changes and click on File < Save. Click on Run < Run Module (or F5) to run the python script. Done.
This is great for people that want to use python 2.7 or just don't want to install the python application from the Microsoft store.
Sometimes the order in which the PATH environment variable is set also matters; if the Windows store variable is before the path where Python is installed then the windows store will open when you type python.
I have installed on my system several Python interpreters, 2.x and 3.x versions. I am trying to prepare my work environment to allow easily switch between code written in both Python version. It is really important to have as much flexible setting in Visual Studio Code (VSC).
The problem is that I have no idea how to set VSC terminal to run code in Python 2.x. Terminal output is needed because it allows to provide user input easily.
I've tried instructions provided on VSC page, like manual interpreter's path indication in folder or workspace setting. I reinstalled Python 2.x to ensure PATH variable has been updated.
When I run code with CodeRunner extension, it always run it in Python 3.x.
Does anyone have similar issue and found how to change Python environment used by this integrated terminal?
All you have to do is press ctrl+shift+p Then will get a search bar kinda thing on top of the screen.
Then type the following command:
> python: select interpreter
You will be provided with options. Select the one you want to use.
At the bottom of the MS Code screen is an info bar that lets you know what line, col, text encoding, etc... It also shows the python interpreter you are accessing.
If you click on the text for the version of python that is running, it will open a list of available interpreters on your system. If 2.7 is in your path, you can select it.
Download and install the python version that you want
https://www.python.org/downloads/
Open the visual studio code
Click on the Bottom left for the version
Select the version that you want the code to be complied
Answers above won't change interpreter in the visual-studio's terminal as explained. You can see for yourself. (I'm on linux)
which python3
# /usr/bin/python3
You can't export a new PATH because it'll ruin your other commands. And neither you can directly change the 'python3' file via root privileges. It doesn't work that way.
Your best option is to reshape your system interpreter according to your needs.
I'm a complete newbie trying to use pycharm with python but my interpretor shows a version of 2.7 when i have installed 3.6. Totally confused and need help!
On pycharm I do the following steps:
Preferences > Python Console > Python Interpretor
I only see Python 2.7.8 (/Library/Framework/....) and beneath this I see options beginning with (/Library/Framework.... ) <-- some of these end in bin/python3.6
I am not sure how to configure Pycharm to use the new version of Python. Being a complete newbie I am really confused as to what to do? and whether changing this makes any difference.
Any help would be much appreciated.
Thanks!
Go to File > Settings > Project > Project Interpreter (it should take you there automatically as soon as you open Settings) and select the version you want to use from the drop-menu. If it is not there, try restarting PyCharm (if it was active whilst the Python 3 installation) - else, it probably means you didn't install Python 3 properly.
First, you need to know where is python installed with the command which python (in some cases this command output you the location of python-2.7, but you can try this other command for python-3.x which python3) if you are in debian the output it gonna see like this /usr/bin/python this is the folder where all (usually) all your python version
Second,Enter to Pycharm: settings/Project:#name of your Project#/Project interpreter In the top of this window you can see a option called project interpreter it actually have a location of the actual python that pycharm run, yo change it use this example:
/usr/bin/pythonX
Where X is the version of python.
in my case:
/usr/bin/python3.6
I'm new to programming and just started a course on Python. I want to use PyCharm, so I downloaded and intalled it (v. 4.5, community edition). I had previously installed Python 3.5 64-bit from python.org (I'm using Windows 10).
To start using PyCharm, I need a project interpreter, which I can select in the settings. As far as I'm concerned, the interpreter is "py.exe", but when I select it, I get this error message: "The selected file is not a valid home for Python SDK". I also tried to use every file whose name contained "python" or "py", and failed.
On every website and video I see, they select a file called "python.exe", but they're using Python 3.4 or a previous version. I checked that PyCharm supports 3.5 ("Initial support for Python 3.5").
Is there anything I'm doing wrong? What should I do to be able to use PyCharm?
All replies are appreciated. Thanks in advance.
file > new project settings > project Interpreter > click in the drop down and select 'show all' > click the '+' button >
Now, in the Virtualenv Environment tab under the New environment radio button, check the path in the 'Base interpreter:' field. For me, mine was set to an invalid path. Once I had corrected the path to point to python.exe I recreated my new project and PyCharm built the virtualenv.
For me there was a bit more too.... When creating the new project I expanded the drop down and had to verify the directory where the venv directory was being created. Once I had corrected the path here I had to click around a bit to get it to let me create the project.
I'm going to chaulk this up to a bug. I'm using Community edition.
When creating a project in PyCharm, if the interpret is not already selected, in the drop down menu under the projects "Location:", you can click the gear-looking icon to the right of the interpreter option, and click "Add Local"; then select the file location of the python.exe file that you have installed. It will probably be C:\Python35\Python.exe
I faced a Similar issue and was not able to find Python interpreter anywhere on the system.
The problem with it was that python was installed directly with default settings and there was no exe found in
C:\Python35\
and to solve this i tried uninstalling and reinstalling with custom settings and selecting allow for all users as well which did the trick and path was set correctly to
C:\Python35\python.exe.
After whichPycharm was able to detect the interpreter on this path.
PyCharm project interpreter problem Resolved
I installed anaconda python distribution (Anaconda3-5.0.1-Windows-x86_64.exe) from the anaconda website. https://anaconda.org/anaconda/python
What it actually did was it re-installed my Python3.6.3 (pertinent to mention I have windows10, with pyCharm community & python 3.5 already but with the interpreter problem and while installing anaconda I chose the following settings and disabled my antivirus before my anaconda installation):
selecting allow for all users
installation path was set correctly and (stored safely for future)
restart my Computer after installation.(not essential-but I did)
opened Anaconda & Jet brian pycharm
selected new project in PyCharm screen shot of my New project default Python interpreter location = C:\Users\Skboy\PycharmProjects\dani Interpreter = C:\Users\Skboy\AppData\Local\Programs\Python\Python36-32\python.exe
Wow! my pyCharm started working for me,
Resolution : Python6.3 re-installation with proper custom setting
make a python test test1.py program file to print "hello python test world"
Run
now my Python Interpreter(automatically -by default select) Python 3.6.3
edit configuration & check for interpreter
(C:\Users\user1\AppData\Local\Programs\Python\Python36-32\python.exe)
Run
success test Run
worth to mention Anaconda Jupyter is a web based can also be used in case novice user are still having problems
I have had the exact same problem and was unable to find the solution until just now. Hopefully this works for anyone that was struggling with it.
I went to the location of the Python 3.5 (32-Bit) in my C: Drive which it turns out is just a shortcut to the actual Python application, right click on it and select Open file location which should direct you to the application version of python - simply called 'python'. This is the .exe file that PyCharm was looking for to use as the interpreter.
Now go to the configure interpreter menu in Pycharm and type in the file location of the actual python application. To get to mine I had to go to AppData/Local/Programs/Python/Python35-32. Click on the python.exe file and it should work.
This is my first post here so if its formatted incorrectly or doesn't use the conventional terms - sorry. Let me know if the solution worked for anyone else with the problem or if I fluked it.
If you kept the default settings while installing python, Your project interpreter for PyCharm will be:
C:\Users\yourUserName\AppData\Local\Programs\Python\Python36\python.exe
Chose the above location as your project interpreter inside PyCharm.
Depending on which python version you have, it could be either Python36\python.exe or Python35\python.exe.
For me the following solution it worked:
My configuration:
Pycharm Community edition 2019.1.1
Anaconda distribution with python 3.7. Interpreter in standard location.
Problem:
Pycharm was not able to find python interpreter after reinstallation of anaconda distribution.
Solution:
- Make sure you run pycharm as admin (right click and run as admin). This was actually the critical step.
- Create new project (or open an existing one)
- Depending on the choice choose interpter or go to file > settings > project interpreter > choose small gear on rights side > add > on base interpreter choose the 3 dots > paste the location of the interpreter in the anaconda distribution.
Hope it helped someone. For me the blocking point was that for some reason pycharm was not launching with admin rights.
