“`python
from firebase_admin import db

Reference to the database

ref = db.reference(“users”)

Creating a new user

ref.push({
“name”: “John Doe”,
“email”: “[email protected]”,
“age”: 30
})
“`

This code creates a new node under “users” and pushes user data into the database.

Reading Data from Firebase

To read data, you can retrieve it as follows:

python
users = ref.get()
print(users) # This will return all user data in the specified reference.

Updating Existing Data

To update data, simply use the update() method:

python
user_ref = ref.child("<user_id>")
user_ref.update({
"age": 31
})

Replace <user_id> with the actual ID of the user record you want to update.

Deleting Data

To delete a specific data entry, use the delete() method:

python
user_ref.delete() # Deletes the user record

Using Firebase Authentication with Python

Firebase Authentication allows you to manage users easily. Here’s how to set it up in Python.

Step 6: Setting Up Authentication

You can enable different sign-in methods in your Firebase Console (Email/Password, Google, etc.). For this example, we’ll focus on Email/Password authentication.

Creating a New User

To create a new user in Firebase Authentication:

“`python
from firebase_admin import auth

Create a new user

user = auth.create_user(
email=”[email protected]”,
password=”password123″
)
print(“Successfully created new user:”, user.uid)
“`

Signing in a User

To sign in and verify a user’s credentials, you can do the following:

“`python

This requires additional libraries, such as requests

import requests

email = “[email protected]”
password = “password123”

Sign-in endpoint

url = “https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=YOUR_API_KEY”

Request payload

payload = {
“email”: email,
“password”: password,
“returnSecureToken”: True
}

response = requests.post(url, json=payload)
if response.status_code == 200:
print(“User signed in successfully:”, response.json())
else:
print(“Error signing in:”, response.json())
“`

Replace YOUR_API_KEY with your actual Firebase project’s Web API Key, which can be found in the project settings.
