How to Create a Virtual Environment on Mac

Steps

Open Terminal
Navigate to your project directory (or where you want the virtual environment to be created):
```
cd /path/to/your/project
```

Create the virtual environment:

python3.12 -m venv pythonclass-py-3.12
python3 -m venv pythonclass-py-3.12

Activate the virtual environment:
```
source pythonclass-py-3.12/bin/activate
```
Verify Python version inside the virtual environment:
```
python --version
```
Install any necessary packages:
```
pip install -r requirements.txt
```
Deactivate the virtual environment:
```
deactivate
```

Download the Python Installer:
- Go to the official Python website:
  https://www.python.org/downloads/windows/
- Click on the latest Python 3.x version (for example, Python 3.12.x).
Run the Installer:
- Open the downloaded .exe file.
- Important: On the first installation screen, check the box that says:
  Add Python 3.x to PATH
- Click Install Now to proceed with default settings.
Wait for Installation to Complete:
- The installer will install Python and pip (the package manager).
- Once done, click Close.
Verify Python Installation:
- Open Command Prompt (search cmd).
- Type:
```
python --version
```
- You should see the installed Python version, e.g., Python 3.12.x.
Verify pip Installation:
- In the same Command Prompt, type:
```
pip --version
```
- This confirms pip is installed and working.

You can install multiple versions (like 3.10, 3.12) and use tools like py launcher or virtual environments to select which version you want to run.

Open Command Prompt or PowerShell
Navigate to your project directory (or where you want the virtual environment to be created):
```

   python3.12 -m venv pythonclass-py-3.12

Command Prompt

pythonclass-py-3.12\Scripts\activate.bat

For PowerShell:

.\pythonclass-py-3.12\Scripts\Activate.ps1

Verify Python version inside the virtual environment:
```
python --version
```
Install any necessary packages:
```
pip install -r requirements.txt
```
Deactivate the virtual environment:
