I am new to programming and I'm attempting to run pypy 3.7 on windows for a project and have had zero success. My partner found
these instructions but following them didn't seem to work. Is the problem with the prompt, installation, python, anything else?? Any and all help would be very appreciated, thank you.
You may have an incompatible Python version. PyPy doesn't support the latest version of Python 3.5, so you may need to install an earlier version of Python.
Also follow this thread: How to install Pypy for Python 3.5?

Would anybody know how to change the version I use in Py-Script? Currently my Py-Script is using python 3.10, but I would like to be able to use python 3.6.
I had python 3.10 and 3.6 installed, so i tried removing 3.10, but that didn't work, as I also expected, but other than that, I have no clue how to and have had no luck finding any information on the topic online.
I'm quite new to programming, so any help would be greatly appreciated!
You cannot easily change the Python version. Python is included with Pyodide which PyScript loads. Changing the version would require rebuilding Pyodide.
Note: I am not sure if it would be possible to use vanilla Python 3.6 with the current version of Pyodide.
Improve your code to work with Pyodide's bundled version of Python.
Or where is there a published list of the supported versions of Python for Visual Studio Code?
Also if one's machine's OS makes a difference that would be helpful to know as well.
According to their documentation, if you link to what "a supported Python", is, the requirements are "whichever version of Python you want to use". And they explicitly include:
The built-in Python installation on Linux.
An installation through Homebrew on macOS using brew install python3 (the system install of Python on macOS is not supported).
A download from python.org.
A download from Anaconda (for data science purposes).
Of course python.org has versions all the way back to 0.9.1, although I suspect anything older than the 2.0.1 in the main downloads doesn't really count.
More realistically, they probably only test with current Python versions, which as of right now means 2.7, 3.5, 3.6, and maybe 3.7 prereleases. If you wanted to use 2.5 or 3.3, you might well get syntax highlighting and error fly-checking based on 2.7 or 3.5 grammar, etc. But actually running your code should still work.
Also, if you're on a Mac and thinking of Homebrew, it's worth noting that brew install python3 will give you an error; the package is just called python now, and you install python for 3.x and python#2 for 2.x.
Microsoft's Python Extension for VS Code actually let you select an interpreter from a list of detected or manually set environments (CMD-Shift-P/Ctrl-Shift-P -> Python: Select Interpreter), so it should work with latest version of any interpreter, as long as is supported by the OS (remember that VS Code and its extensions are hosted in Electron).

I have python 2.7.6 and 3.4 on my mac installed currently. I want to upgrade python2 to python 2.7.8 as I believe it is the more secure. What is the right way to do this? Do I simply download the installer from the website and run it? If so, will my system automatically use 2.7.8 over the previously installed 2.7.6?
Note, the python version 2.7.6 came pre-installed. And I apologize if the question seems redundant. I used to develop blindly without any thought of the versions and packages and made a mess of my projects. So now I try to careful.
pyenv is a simple Python version management. You can find more on pyenv.
I have installed the Python IDE Spyder. For me it's a great development environment.
Some how in this process I have managed to install three versions of Python on my system.These can be located as following:
Version 2.7.6 from the OS X Terminal;
Version 2.7.8 from the Spyder Console; and
Version 2.7.9rc1 from an IDL window.
The problem I have is (I think) that the multiple versions are preventing Spyder from working correctly.
So how do I confirm that 2.7.6 is the latest version supported by Apple and is there a simple way ('silver bullet') to remove other versions from my system.
I hope this is the correct forum for this question. If not I would appreciate suggestions where I could go for help.
I want to keep my life simple and to develop python software in the Spyder IDE. I am not an OS X guru and I really don't want to get into a heavy duty command line action. To that end I just want to delete/uninstall the 'unofficial versions' of Python. Surely there must be an easy way to do this - perhaps 'pip uninstall Python-2.7.9rc1' or some such. The problem is that I am hesitant to try this due to the fear that it will crash my system.
Help on this would be greatly appreciated.
(Spyder dev here) There is no simple way to do what you ask for, at least for the Python version that comes with Spyder.
I imagine you downloaded and installed our DMG package. That package comes with its own Python version as part of the application (along with several important scientific packages), so it can't be removed because that would imply to remove Spyder itself :-)
I don't know how you installed IDL(E?), so I can't advise you on how to remove it.
Hi
I just want to install mercurial but for all versions it needs python 2.6, I tried to use .rpm file but the only thing I got is lots of lines full of error which tells: need old versions before 2.6 and after 2.5 which is installed on my linux. any help would be appreciated.

Go to ActiveState and download their versions: https://www.activestate.com/activepython/downloads
It's much easier than using the .rpms.
Which distribution are you using? I would recommend you to upgrade your system to a newer version of your linux distro, whatever it is. Modern Linux distros are using at least python2.6 now.
If you do not want to upgrade your system with various reasons, ActiveState's python version as stated in Jasie's answer is good for your cause. It installs python in your system without breaking anything, just you have to add some lines in your .bashrc to force system find your ActiveState python installation before the system's python.
Another alternative would be installing earlier version of mercurial which supports the python version installed on your system. But I would not recommend you to do so..
Among these, my suggestion is upgrading your system to a merely "up-to-date" version, so that python2.6 or higher is installed on your system.
