1. Import necessary modules:

from flask import Flask

1. Create Flask instances for each application:

app1 = Flask(__name__)
app2 = Flask(__name__)

1. Define routes for each application:

@app1.route('/app1')
def app1_route():
    return 'Hello from App 1'

@app2.route('/app2')
def app2_route():
    return 'Hello from App 2'

1. Run each application with different port numbers:

if __name__ == '__main__':
    app1.run(port=5000)
    app2.run(port=5001)

1. Save the script with a filename (e.g., multiple_apps.py) and run it in the terminal:

python multiple_apps.py
