Error handling and rate limits in Prompt Engineering / GenAI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to catch an error when the API call fails.

Prompt Engineering / GenAI

try:
    response = api_call()
except [1]:
    print("API call failed")

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

AKeyError

BValueError

CTimeoutError

DException

3 left

💡 Hint

Common Mistakes

Using a specific error that may not catch all API failures.

The Exception class catches all errors, which is useful for handling any API call failure.

2fill in blank

medium

Complete the code to check if the API response status code indicates rate limiting.

Prompt Engineering / GenAI

if response.status_code == [1]:
    print("Rate limit exceeded. Please wait.")

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

A404

B429

C200

D500

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing 429 with 404 or 500 status codes.

Status code 429 means too many requests, indicating rate limiting.

3fill in blank

hard

Fix the error in the code to retry the API call after a delay when rate limited.

Prompt Engineering / GenAI

import time

if response.status_code == 429:
    time.sleep([1])
    response = api_call()

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

A0.5

B-1

C5

D"5"

Attempts:

💡 Hint

Common Mistakes

Passing a string instead of a number to time.sleep.

Using negative sleep time.

The time.sleep() function requires a positive number of seconds as a float or int. Using 5 seconds is a common retry delay.

4fill in blank

hard

Fill both blanks to handle API errors and retry with exponential backoff.

Prompt Engineering / GenAI

max_retries = 3
retry_delay = 1
for attempt in range(max_retries):
    response = api_call()
    if response.status_code == 200:
        break
    elif response.status_code == [1]:
        time.sleep(retry_delay)
        retry_delay [2] 2

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

A429

B*=

C+=

D500

💡 Hint

Common Mistakes

Using '+=' instead of '*=' for exponential backoff.

Checking wrong status codes.

When rate limited (status 429), the code waits and doubles the delay each retry using *= for exponential backoff.

5fill in blank

hard

Fill all three blanks to log errors, handle rate limits, and raise exceptions after retries.

Prompt Engineering / GenAI

import logging

max_retries = 2
retry_delay = 1
for i in range(max_retries + 1):
    response = api_call()
    if response.status_code == 200:
        break
    elif response.status_code == [1]:
        logging.warning(f"Rate limit hit, retrying in {retry_delay} seconds")
        time.sleep(retry_delay)
        retry_delay [2] 2
    else:
        logging.error(f"API error: {response.status_code}")
        raise [3]("API call failed")

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

A429

B*=

CException

DValueError

Attempts:

3 left

💡 Hint

Common Mistakes

Raising wrong exception type.

Using wrong operator for retry_delay.

Checking incorrect status code.

The code handles rate limit with status 429, doubles retry_delay with '*=', and raises a general Exception on other errors.
