💡 Hint

Common Mistakes

Adding the model's response instead of the user's message.

Appending the entire conversation history again.

The conversation history stores all user messages and model responses. Here, we add the latest user message.

2fill in blank

medium

Complete the code to retrieve the last 3 messages from the conversation history.

Prompt Engineering / GenAI

recent_history = conversation_history[1]

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

A[:3]

B[3:]

C[-3:]

D[-1:]

Attempts:

💡 Hint

Common Mistakes

Using positive indices which get the first items instead of last.

Using only one negative index which gets only one item.

Using [-3:] slices the list to get the last three messages.

3fill in blank

hard

Fix the error in the code that tries to clear the conversation history.

Prompt Engineering / GenAI

Ddelete

💡 Hint

Common Mistakes

Using remove() which requires an argument.

Using pop() which removes only the last item.

The clear() method empties the list. Other options either remove one item or are invalid.

4fill in blank

hard

Fill both blanks to create a dictionary of message counts by speaker.

Prompt Engineering / GenAI

counts = {speaker: conversation_history.count([1]) for speaker in [2]

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

A'user'

B'assistant'

C['user', 'assistant']

D'system'

Attempts:

3 left

💡 Hint

Common Mistakes

Using a single string instead of a list for speakers.

Counting 'assistant' messages inside the 'user' count.

We count how many times the string 'user' appears for each speaker in the list ['user', 'assistant'].

5fill in blank

hard

Fill all three blanks to filter conversation history for user messages longer than 10 characters.

Prompt Engineering / GenAI

filtered = [msg for msg in conversation_history if msg[1] [2] and len(msg) [3] 10]

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

Astartswith

B== 'user'

C>

Dendswith

Attempts:

💡 Hint

Common Mistakes

Using 'endswith' instead of 'startswith'.

Using '<' instead of '>' for length comparison.

The code filters messages that start with 'user' and have length greater than 10.
