💡 Hint

Common Mistakes

Using 'append' which is for lists, not dictionaries.

Using 'remove' which deletes data instead of retrieving.

Using 'update' which changes data instead of fetching.

The 'get' method retrieves the value for the given key from the memory store.

Complete the code to check if a memory key exists before retrieval.

Agentic AI

if '[1]' in memory_store:
    data = memory_store['[1]']

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

💡 Hint

Common Mistakes

Using variable names instead of the actual key string.

Forgetting to check key existence before access.

We check if the specific key 'user_456' exists in the memory store before accessing it.

3fill in blank

hard

Fix the error in the code to retrieve the most recent memory entry.

Agentic AI

recent_memory = memory_list.[1]()

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

Aappend

Bpop

Csort

Dclear

Attempts:

💡 Hint

Common Mistakes

Using 'append' which adds items instead of retrieving.

Using 'sort' which rearranges the list but does not retrieve an item.

Using 'clear' which empties the list.

The 'pop' method removes and returns the last item, which is the most recent memory in a list.

4fill in blank

hard

Fill both blanks to filter memories with scores above 80.

Agentic AI

high_scores = {mem: score for mem, score in memory_scores.items() if score [1] [2]

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

A>

B80

C<

D==

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' which filters lower scores.

Using '==' which filters only exact matches.

We use '>' to filter scores greater than 80.

5fill in blank

hard

Fill all three blanks to create a dictionary of memories with length greater than 5.

Agentic AI

filtered_memories = { [1]: [2] for [3] in memories if len(memories[[3]]) > 5 }

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

Amem

Bmemories[mem]

Dmemory

Attempts:

3 left

💡 Hint

Common Mistakes

Using different variable names inconsistently.

Using the key as the value instead of accessing the dictionary.

We use 'mem' as the key variable, 'memories[mem]' as the value, and iterate with 'mem' over memories.
