Step 1: Download Python

1. Go to the official website: Python Downloads
2. Download the latest Python 3.x (64-bit installer) (most common for Windows).

Step 2: Install Python (Important Settings)

When the installer opens:

Check these boxes before clicking "Install":

• Add Python to PATH (so you can use  python  from Command Prompt).
• Choose Customize Installation if you want, otherwise click Install Now.

This ensures Windows knows where to find Python.

Step 3: Verify Python Installed

Press Win + R, type  cmd (for Command Prompt) or powershell , and hit Enter

Type:  python --version

or:  py --version

Expected:

Python 3.12.x

Step 4: Verify pip Installed

Press Win + R, type  cmd   (for Command Prompt) or  powershell , and hit Enter

Type:  pip --version

Expected:

pip 24.x from C:\Users\YourName\AppData\Local\Programs\Python\Python312\Lib\site-packages\pip (python 3.12)

If pip isn’t found, install it with:  python -m ensurepip --upgrade

Step 5: Navigate to Your Project Folder

In the command line, use  cd   to move into the folder where you want the environment:

cd path\to\your\project

Example:

cd C:\Users\YourName\Projects\MyApp

Step 6: Create the Virtual Environment

In the command line type:

python -m venv myenv

• python           → Calls Python installed on your system.
• -m venv          → Uses the built-in          venv           module.
• myenv           → Name of the virtual environment folder (you can choose any name).

This will create a folder called          myenv           in your project directory.

Step 7: Activate the Virtual Environment

In the command line type:

myenv\Scripts\activate

If successful, you’ll see the environment name at the start of your command line, for example:

(myenv) C:\Users\YourName\Projects\MyApp>

Step 8: Install Jupyter Notebook and packages

In the virtual environment:

Type to intall and run Jupyter Notebook:

pip install jupyter notebook

jupyter notebook

Type to install packages for your application:

pip install package_name      

Step 9: Deactivate When Finished

To exit the virtual environment, just type in the command line:

deactivate
