How to downgrade python 3.10 to 3.9

To downgrade python 3.10 to 3.9, you need to first download the version you want to use from the official Python website, and you have to install the software like a normal package. Once done, run the following code

cd /Library/Frameworks/Python.framework/Version

After this, the ‘ls’ needs to be executed to the list of all Python versions installed. You should run this code

this is how you start downgrading the Python version.

Check out how you downgrade Python 3.10 to 3.9 using different systems

For Windows

If you are using windows, use the following steps

• First, install the version of Python you want by opening the command prompt to enter pip install vistualenv.
• After that, type virtualenv \path\to\env -p \path\to\python_install.exe in your command prompt, where \path\to\python_install.exe shows you where is the Python version, and the \path\to\env guides you about the path where you have a virtual environment.
• Now, using the \path\to\env\Scripts\activate.bat, you can activate the virtual environment.

For Linux

• Just download the version of Python you want to use from the official site as a normal package. Then run the following code

cd /Library/Frameworks/Python.framework/Version

• Execute ‘ls’ if you want to list all the Python installed versions. And then, run the following to remove the Python version 3.9, which you like to be deleted.

sudo rm -rf 3.9 :: Remove the Python version 3.9

• once all is done, just check Python3 -v to get the version you want to install.

Conclusion

Here, we have discussed all the systems one can you for Python programming to know how to downgrade Python 3.10 to 3.9. I hope you can easily get the version you want to use.
