State persistence across sessions in Agentic AI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to save the agent's state to a file.

Agentic AI

with open('agent_state.pkl', [1]) as f:
    pickle.dump(agent_state, f)

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

💡 Hint

Common Mistakes

Using 'w' instead of 'wb' causes errors when saving binary data.

Using 'r' or 'rb' opens the file for reading, not writing.

The agent's state is saved in binary mode, so 'wb' (write binary) is needed.

2fill in blank

medium

Complete the code to load the agent's state from a file.

Agentic AI

with open('agent_state.pkl', [1]) as f:
    agent_state = pickle.load(f)

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

💡 Hint

Common Mistakes

Using 'r' instead of 'rb' causes errors when loading binary data.

Using 'w' or 'wb' opens the file for writing, not reading.

Loading pickled data requires reading in binary mode, so 'rb' is correct.

3fill in blank

hard

Fix the error in the code to correctly save the agent's state.

Agentic AI

pickle.dump(agent_state, open('state.pkl', [1]))

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

💡 Hint

Common Mistakes

Using 'w' causes errors because pickle needs binary mode.

Using 'r' or 'rb' is for reading, not writing.

Saving with pickle requires opening the file in write binary mode 'wb'.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that saves only keys with values greater than 10.

Agentic AI

filtered_state = {k: v for k, v in agent_state.items() if v [1] 10 and isinstance(v, [2])}

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

A>

Bint

C<

D!=

💡 Hint

Common Mistakes

Using '<' or '==' instead of '>' changes the filter condition.

Using wrong type in isinstance causes no filtering.

We want values greater than 10 and to check if value is an int (using 'int').

5fill in blank

hard

Fill all three blanks to update the agent's state, save it, and then load it back.

Agentic AI

agent_state[[1]] = [2]
with open('agent_state.pkl', [3]) as f:
    pickle.dump(agent_state, f)

with open('agent_state.pkl', 'rb') as f:
    loaded_state = pickle.load(f)

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

A'last_action'

B'new_value'

C'wb'

D'rb'

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong file mode causes errors when saving.

Using wrong key or value names breaks the update.

We update the key 'last_action' with 'new_value', then save with 'wb' mode.
