Setting Up a Python Virtual Environment (venv)

This guide will walk you through the process of setting up a Python virtual environment (venv) for the project.

Prerequisites

• Python 3.x installed on your system
• pip (Python package installer) installed

Steps to Set Up a Virtual Environment

1. Check Python Installation

Ensure you have Python installed by running the following command:

python --version

or, if you have multiple versions of Python installed:

python3 --version

2. Install venv (if not already installed)

The venv module is included in Python 3.3 and above. If it's not installed, you can install it using:

pip install virtualenv

3. Create a Virtual Environment

Navigate to your project directory and create a virtual environment by running:

python -m venv env

or, if you are using python3:

python3 -m venv env

This command creates a directory named env that contains the virtual environment.

4. Activate the Virtual Environment

On Windows

.\env\Scripts\activate

On macOS and Linux

source env/bin/activate

After activation, you should see (env) prefixed to your command prompt, indicating that the virtual environment is active.

5. Install Dependencies

With the virtual environment activated, you can now install any project dependencies. For example:

pip install <package_name>

6. Deactivate the Virtual Environment

To deactivate the virtual environment, simply run:

deactivate

Additional Necessities

Using a requirements.txt File

To create a requirements.txt file that lists all installed packages, run:

pip freeze > requirements.txt

To install the dependencies listed in a requirements.txt file:

pip install -r requirements.txt

Virtual Environment Naming

You can name your virtual environment anything you like. For example, you might use venv, myenv, or any other descriptive name.

Running Sypflix

Now, to access the WebApp, simply run

python app.py

or, if you are using python3:

python3 app.py

After doing the steps above, the website should be locally deployed in

localhost:3000
