We have already done the Flask dev environment setup for VS Code in Tutorial Part -1: Flask installation and setup in Visua...      
       
In Flask tutorial part #1, we have created the folder hello_flask, that folder is opened in Visual studio code as you can see here.

Let's create an app and then start a server then we run the app from the browser.

Step 1: create a new file with the name, app.py and save it.
Step 2: Now we write the following lines of code in this file --
   from flask import Flask
   app = Flask(__name__)
 
@app.route("/")
   def home():
   return "Hello, Flask!"
 
save the app.py file (Ctrl+S).
 
Step 3: Now Run the flask server by using a terminal with the command -
       python -m flask run

which runs the Flask development server. The development server looks for app.py by default.

  note: If you see an error that the Flask module cannot be found,
          then run the following command:  python -m pip install flask  
                                 and restart VS Code once.
   
Step 4: Also, if you want to run the development server on a different IP address or port, use the host and port command-line arguments, as with --host=0.0.0.0 --port=80.    
   
Step 5: Run the app from the browser.      

Step 6: Stop the app by using Ctrl+C in the terminal.
