First you have to install Anaconda or Miniconda from here: https://docs.anaconda.com/free/anaconda/install/mac-os/
If conda is installed, now you’ll be able to create your own virtual environemnt for further development. Here is the command for creating , activating and deactivating a virtual environment of Python.
conda create -n
python=3.9
. Follow all informations in command terminal window. (Normally I suggest you to select [Y] all the time).
After completion of the given command you can activate your virtual environment using following command:
conda activate
If you want to deactivate the environment, use this command: conda deactivate
