Setting Up a Python Virtual Environment (venv) on a Mac

1. Install Python (if not already installed)

Check if Python is installed:

python3 --version

If Python is not installed, download and install it from python.org.

2. Create a Virtual Environment

Navigate to the directory where you want to create the virtual environment and run:

python3 -m venv myenv

Replace myenv with your desired virtual environment name.

3. Activate the Virtual Environment

source myenv/bin/activate

Once activated, your terminal prompt will change, showing (myenv) before the command line.

4. Deactivate the Virtual Environment

To exit the virtual environment, use:

deactivate

5. Best practice location for Virtual Environments

Virtual environments are typically stored in your project directories. exmple init and activate below:

cd my_project
python3 -m venv venv
source venv/bin/activate
