1. Setup a Python Virtual Environment

A virtual environment is a tool that helps to keep dependencies required by different projects separate by creating isolated python virtual environments for them.

Create a Project Folder.

Run following command to create a new virtual environment inside your project folder:

python -m venv myvenv
After running above command, a folder named myvenv will get created in your project folder.
Activate the virtual environment by running following command: For ubuntu and mac users:

source myvenv/bin/activate

For windows users:

myvenv\Scripts\activate

2. Install required Python Packages:

flask : pip install flask

twilio : pip install twilio

3. Create a Flask App (app.py)

python app.py

(or)

Manual Flask Run :

For CMD :

$ export FLASK_APP=hello.py

$ export FLASK_DEBUG=1

$ flask run

For PowerShell :
