Agent memory and state in Prompt Engineering / GenAI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to initialize an agent's memory as an empty list.

Prompt Engineering / GenAI

agent_memory = [1]

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

ANone

B{}

C[]

D0

💡 Hint

Common Mistakes

Using {} which creates an empty dictionary instead of a list.

The agent's memory should start as an empty list to store past interactions.

2fill in blank

medium

Complete the code to add a new state entry to the agent's memory list.

Prompt Engineering / GenAI

agent_memory.[1](new_state)

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

Aappend

Bextend

Cinsert

Dremove

💡 Hint

Common Mistakes

Using extend which expects an iterable, not a single item.

Use append to add a single new state to the end of the memory list.

3fill in blank

hard

Fix the error in the code to retrieve the last state from the agent's memory.

Prompt Engineering / GenAI

last_state = agent_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 state, not the last.

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

4fill in blank

hard

Fill both blanks to update the agent's current state and save it in memory.

Prompt Engineering / GenAI

current_state = [1]
agent_memory.[2](current_state)

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

Aget_new_state()

Bappend

Cpop

Dupdate

💡 Hint

Common Mistakes

Using pop which removes an item instead of adding.

First, get the new state using get_new_state(), then add it to memory with append.

5fill in blank

hard

Fill all three blanks to create a dictionary of states with their timestamps and filter recent states.

Prompt Engineering / GenAI

state_log = [1]: [2] for [3] in agent_memory if [2]['timestamp'] > cutoff_time

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

Astate['id']

Bstate

Dstate['timestamp']

💡 Hint

Common Mistakes

Using timestamp as key which may not be unique.

This dictionary comprehension uses the state's id as key, the full state as value, and iterates over each state in memory.
