Refer steps to setup and install Python and Flask Virtual Environment

What is virtual environment in Python?

A virtual environment virtualenv is used to create independent, separate virtual environments with their own dependencies for multiple project. It generates a new folder for the new virtual environment which has its own libraries folder, pip, and Python interpreter for the Python version used to activate the environment.

Follow the steps listed below to begin the project:

1. Create a new virtual environment
2. Select Python Interpreter
3. Use new virtual environment for the python project
4. Activate your new created virtualenv
5. Install Flask if not available
6. Create a new file called app.py in the python project and print the simple text using below code.

   from flask import Flask
   app = Flask(__name__)
   
   @app.route("/welcome")
   def welcome():
     return "TechGeekNext - Python Example"
   

7. Run python flask example app.py using Flask run command.
8. Test the Restful Api GET Request http://127.0.0.1:5000/welcome.
