Hi @Sean_Chrollo,

  1. if __name__ == "__main__":: This line checks whether the script is being run directly as the main program. The __name__ variable is a special variable in Python, and when the script is executed, __name__ is set to "__main__" if it is the main program.
  2. app.run(debug=True, host="0.0.0.0", port=3000): If the script is being run as the main program, this line starts the Flask development server. The server will run in debug mode (debug=True), listen on all public IPs (host="0.0.0.0"), and use port 3000 (port=3000). The development server is useful during the development phase and automatically reloads the application when changes are made.

I hope this helps!
Happy Learning
