Episodic memory for past interactions in Agentic AI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to initialize an empty episodic memory list.

Agentic AI

episodic_memory = [1]

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

Aset()

B{}

C[]

DNone

💡 Hint

Common Mistakes

Using a dictionary {} instead of a list.

Using None which is not a container.

We use an empty list [] to store episodic memory entries in order.

2fill in blank

medium

Complete the code to add a new interaction record to episodic memory.

Agentic AI

episodic_memory.[1]({'user': user_input, 'response': agent_reply})

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

Aappend

Bextend

Cinsert

Dupdate

💡 Hint

Common Mistakes

Using extend which expects an iterable.

Using update which is for dictionaries.

The append method adds a single new item to the end of the list.

3fill in blank

hard

Fix the error in retrieving the last interaction from episodic memory.

Agentic AI

last_interaction = episodic_memory[1]

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

A[1]

B[0]

C[-2]

D[-1]

💡 Hint

Common Mistakes

Using [0] which gets the first item.

Using [1] which gets the second item.

Using [-1] accesses the last item in the list, which is the most recent interaction.

4fill in blank

hard

Fill both blanks to filter episodic memory for interactions where user said 'hello'.

Agentic AI

hello_interactions = [entry for entry in episodic_memory if entry[1] 'user' [2] 'hello']

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

A['user']

B==

C!=

D.get('user')

💡 Hint

Common Mistakes

Using .get('user') which is valid but not the intended answer here.

Using != which checks inequality.

We access the 'user' key with ['user'] and check equality with == to 'hello'.

5fill in blank

hard

Fill all three blanks to create a summary dictionary of user inputs and agent responses.

Agentic AI

summary = [1]: [2] for [3] in episodic_memory

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

A{entry['user']

Bentry['response']

Centry

Dentry['user']

💡 Hint

Common Mistakes

Using incorrect dictionary syntax.

Using wrong keys or variable names.

The dictionary comprehension uses {entry['user']: entry['response'] for entry in episodic_memory} to map user inputs to responses.
