try:

python3 -u "/home/username/Music/code/test.py"

if you are running that from Visual Code, then you need to configure Visual Code to use python3 instead of python (that would have been the name for python2 on older systems - python3 is not named python).

[Pulpy_orange]

How can I configure VS codium or code to use Python3.

[iwalker]

Go into File → Preferences → Settings. Then search for python. Then it should show under Extensions, something like my screenshot below:

sir
i am using VS codium instead of Vs Code,

> Extensions i am using Code runner, i am installed python extension hoping it would work, still no luck and for some strange reason jupitor extesnion automatically installed.

@Pulpy_orange

i am using VS codium instead of Vs Code

Doesn’t it have anything like File → Preferences → Settings ?

[Pulpy_orange]

i posted screenshot showing python is not there.

[jlehtone]

Sorry, missed that.

Nevertheless, if Codium mimics Code, then why would it not have similar, configurable options?

What if you don’t filter with “python” … what Settings are there for User?

[iwalker]

The python option in the screenshot, has a cog wheel in the bottom right hand corner. Click it, chances are you can change the config there. Either that or search python in the workspace option instead of user option. I use official VS Code, rather than some other version of it, so was much easier to find the config options. You’ll have to search through it, if not, just use official VS Code instead.

for java there 3 option for you

1. if you going to use jdk 11 then use this
   sudo dnf install java-11-openjdk-devel
   by the way if you type dnf install java-11-openjdk- then double tab it will show you many option like the documentation if you want to install it also there demo and src code and other option pick what ever you want

2. if you going to use jdk 17 the latest LTS version
   use this sudo dnf install java-17-openjdk-devel
   you can use the same trick in the previous option but with this dnf install java-17-openjdk- then double tab

3. for jdk 8 use this dnf install java-1.8.0-openjdk

this installation will do the path for you so no need to do anything

and for an idea for java i would go for IntelliJ IDEA: The Capable & Ergonomic Java IDE by JetBrains there community version which is free
for easy way to install that ide and it keep updated use there toolbox JetBrains Toolbox App: Manage Your Tools with Ease it’s appimage app after you download it extract it then set the file to be executable right click on the file then properties then permission then check allow executing file as program then click on it and you good to go

hope that help and have a nice day

@JustSomeone @iwalker @jlehtone thanks alot, its working now.
i had to re-install vs codium to work.

VS codium is a community-driven, freely-licensed binary distribution of Microsoft’s editor VS Code.

VS codium just basically VS code without tracking and some proprietary code removed.
give it a try.

[JustSomeone]

@Pulpy_orange you very welcome and happy coding

A good overview of issue, reasons, and solutions can be found at: What, no Python in Red Hat Enterprise Linux 8? | Red Hat Developer

But even the python3 version is quite old. For any serious python development (other than “system” related) it can be useful to create environments using something like miniconda and conda-forge for easy access to modern Python versions and the wealth of packages that go with it.

@maartenb

But even the python3 version is quite old.

The base system tools, e.g. dnf, do use their own copy of python that is and always will be python 3.6.

The AppStream, however, does currently provide python 3.8 and 3.9. You can thus have 3.9 as the python that you see, rather than the 3.6. (Well, up to May 2024, when that stream goes EOL. By then there probably is something newer.)
