Memory persistence and storage in Agentic AI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

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

Agentic AI

with open('memory_store.txt', [1]) as file:
    file.write(memory_data)

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

A'w'

B'r'

C'x'

D'a'

💡 Hint

Common Mistakes

Using 'r' mode which is read-only and causes an error when writing.

Using 'a' mode which appends instead of overwriting.

Using 'w' opens the file for writing and overwrites existing content, which is suitable for saving memory data.

2fill in blank

medium

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

Agentic AI

import json
with open('memory_store.json', 'r') as file:
    memory_data = json.[1](file)

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

💡 Hint

Common Mistakes

Using json.dump which writes JSON instead of reading.

Using json.loads which expects a string, not a file.

json.load reads JSON data from a file object and converts it into a Python object.

3fill in blank

hard

Fix the error in the code that appends new memory data to a list stored in a file.

Agentic AI

import json
with open('memory_store.json', 'r') as file:
    memory_list = json.load(file)
memory_list.[1](new_memory)
with open('memory_store.json', 'w') as file:
    json.dump(memory_list, file)

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

Aappend

Cinsert

Dextend

💡 Hint

Common Mistakes

Using extend which expects an iterable and would add each element separately.

Using add which is not a list method.

append adds a single new item to the list, which is correct for adding one memory entry.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that stores memory keys and their lengths if length is greater than 5.

Agentic AI

memory_lengths = {key: [1] for key, value in memory_store.items() if [2] > 5}

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

Alen(value)

Blen(key)

💡 Hint

Common Mistakes

Using len(key) which measures the key length, not the value.

Checking length of key instead of value in the condition.

We want the length of the value for the dictionary value and to check if the length of the value is greater than 5.

5fill in blank

hard

Fill all three blanks to filter and store memory items where the value is a string longer than 3 characters.

Agentic AI

filtered_memory = { [1]: [2] for [3], val in memory_store.items() if isinstance(val, str) and len(val) > 3 }

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

Bval

Ditem

💡 Hint

Common Mistakes

Using 'item' which is not defined in the loop.

Mixing variable names inconsistently.

The dictionary comprehension uses key and val variables to filter and store items correctly.
