Conda treats Python the same as any other package, so it is easy to manage and update multiple installations.
Conda supports Python 3.8, 3.9, 3.10, 3.11 and 3.12.

python=3.9is the package and version you want to install in this new environment. This could be any package, such as
numpy=1.19, or multiple packages.
Verify that the new environment is your current environment.
To verify that the current environment uses the new Python version, in your terminal window, run:
To use the PyPy builds you can do the following:
conda config --add channels conda-forge
conda config --set channel_priority strict
conda create -n pypy pypy
conda activate pypy
Using a different version of Python#
To switch to an environment that has different version of Python, activate the environment.
To update Python to the latest version in your environment, run:
