Python Firebase Realtime Listener Full Code :

import firebase_admin
from firebase_admin import credentials
from firebase_admin import db

def listener(event):
    print(event.event_type)  # can be 'put' or 'patch'
    print(event.path)  # relative to the reference, it seems
    print(event.data)  # new data at /reference/event.path. None if deleted
    
json_path = r'E:\Projectz\FYP\FreshOnes\Python\PastLocations\fyp-healthapp-project-firebase-adminsdk-40qfo-f8fc938674.json'
my_app_name = 'fyp-healthapp-project'
xyz = {'databaseURL': 'https://{}.firebaseio.com'.format(my_app_name),'storageBucket': '{}.appspot.com'.format(my_app_name)}

cred = credentials.Certificate(json_path)        
obj = firebase_admin.initialize_app(cred,xyz , name=my_app_name)

db.reference('PatientMonitoring', app= obj).listen(listener)

Output:

put
/
{'n0': '40', 'n1': '71'} # for first time its gonna fetch the data from path whether data is changed or not

put # On data changed 
/n1  
725

put # On data changed 
/n0
