Complete the code to define a microservice that handles only user authentication.
class AuthService: def __init__(self): self.users = {} def [1](self, username, password): # Authenticate user return self.users.get(username) == password
The method should be named authenticate because this service is responsible only for user authentication.
Complete the code to separate order processing into its own microservice method.
class OrderService: def [1](self, order_id): # Process the order print(f"Processing order {order_id}")
The method should be named process_order because this service handles order processing only.
Fix the error in the microservice code to ensure it only handles payment processing.
class PaymentService: def process_payment(self, amount): print(f"Processing payment of ${amount}") def {{BLANK_2}}(self, order_id): print(f"Sending receipt for order {order_id}")
The first blank should be amount to correctly print the payment amount. The second method send_receipt fits payment service responsibility better than updating order status.
Fill both blanks to correctly separate user profile and notification services.
class UserProfileService: def update_profile(self, user_id, data): print(f"Updating profile for user {user_id}") class NotificationService: def [1](self, user_id, message): print(f"Sending [2] to user {user_id}")
The notification service should have a method named send_notification and print the word notification to indicate the action clearly.
Fill all three blanks to design a microservice that only manages product inventory.
class InventoryService: def [1](self, product_id, quantity): print(f"Adding {quantity} units to product {product_id}") def [2](self, product_id): print(f"Checking stock for product {product_id}") def [3](self, product_id, quantity): print(f"Removing {quantity} units from product {product_id}")
The inventory service should have methods named add_stock, check_stock, and remove_stock to manage product quantities only. Updating price is outside its responsibility.
