easy

Complete the code to create a Service Bus queue client.

Azure

from azure.servicebus import ServiceBusClient

connection_str = "Endpoint=sb://example.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=key"
queue_name = "myqueue"

client = ServiceBusClient.from_connection_string([1])

💡 Hint

Common Mistakes

Using the queue name instead of the connection string.

Trying to use the client or receiver variables before they are defined.

The ServiceBusClient is created using the connection string to connect to the Azure Service Bus namespace.

medium

Complete the code to send a message to the Service Bus queue.

Azure

from azure.servicebus import ServiceBusMessage

with client.get_queue_sender(queue_name=queue_name) as sender:
    message = ServiceBusMessage("Hello, Service Bus!")
    sender.[1]([message])

💡 Hint

Common Mistakes

Using receive_messages instead of send_messages.

Trying to create or delete messages directly.

The method send_messages is used to send messages to the queue.

Fix the error in receiving messages from the queue by completing the method name.

Azure

with client.get_queue_receiver(queue_name=queue_name) as receiver:
    messages = receiver.[1](max_message_count=5, max_wait_time=10)
    for msg in messages:
        print(str(msg))
        receiver.complete_message(msg)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using send_messages on the receiver object.

Using non-existent methods like get_messages or fetch_messages.

The receive_messages method is used to get messages from the queue.

4fill in blank

hard

Fill both blanks to create a dictionary of message bodies and complete messages.

Azure

with client.get_queue_receiver(queue_name=queue_name) as receiver:
    messages = list(receiver.[1](max_message_count=3))
    results = {msg.[2]: msg for msg in messages}
    for msg in messages:
        receiver.complete_message(msg)

Drag options to blanks, or click blank then click option'

Cmessage_id

Dsend_messages

💡 Hint

Common Mistakes

Using send_messages instead of receive_messages.

Using body instead of message_id as dictionary key.

We receive messages with receive_messages and use message_id as the dictionary key.

5fill in blank

hard

Fill all three blanks to send a batch of messages with custom content.

Azure

from azure.servicebus import ServiceBusMessage

messages = [ServiceBusMessage([1]) for i in range(3)]
with client.get_queue_sender(queue_name=queue_name) as sender:
    sender.[2](messages)

with client.get_queue_receiver(queue_name=queue_name) as receiver:
    received = receiver.[3](max_message_count=3)
    for msg in received:
        print(str(msg))
        receiver.complete_message(msg)

Drag options to blanks, or click blank then click option'

A"Message " + str(i)

Bsend_messages

Creceive_messages

D"Hello"

💡 Hint

Common Mistakes

Trying to concatenate strings inside the list comprehension incorrectly.

Using send_messages on the receiver or receive_messages on the sender.

Each message is created with the content "Message " plus the index. We send messages with send_messages and receive them with receive_messages.
