Common Mistakes

Passing a string instead of a list

Using curly braces which create a set instead of a list

The subscribe method expects a list of topic names. So, ['my_topic'] is correct.

💡 Hint

Common Mistakes

Using a tuple instead of a list

Passing a string with comma-separated topics

The subscribe method requires a list of topic names. So, ['topic1', 'topic2'] is correct.

Common Mistakes

Passing a string instead of a list

Using a set instead of a list

The subscribe method expects a list of topics, so ['events'] is correct. Passing a string alone causes an error.

4fill in blank

hard

Fill both blanks to subscribe the consumer to topics starting with 'data_' and print the subscription list.

Kafka

topics = ['data_1', 'data_2', 'logs']
filtered = [topic for topic in topics if topic.[1]('data_')]
consumer.subscribe([2])
print(consumer.subscription())

💡 Hint

Common Mistakes

Using 'in' instead of 'startswith'

Subscribing to the original list instead of filtered

Use startswith to filter topics starting with 'data_'. Then subscribe using the filtered list.

5fill in blank

hard

Fill all three blanks to subscribe the consumer to topics with length greater than 5 and print the subscription.

Kafka

topics = ['alpha', 'beta', 'gamma', 'delta123']
long_topics = [topic for topic in topics if len(topic) [1] 5]
consumer.subscribe([2])
print([3].subscription())

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

💡 Hint

Common Mistakes

Using less than operator

Printing the list instead of consumer subscription

Use > to filter topics longer than 5 characters, subscribe using long_topics, and print the consumer's subscription.
