Graceful degradation in Rest API - Interactive Code Practice

Practice - 5 Tasks

easy

Complete the code to return a fallback message when the main API call fails.

Rest API

response = call_main_api()
if not response:
    return [1]

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

B"Success"

C"Service unavailable, please try later."

💡 Hint

Common Mistakes

Returning the original response without checking if it failed.

Calling the main API again instead of returning a fallback message.

When the main API call fails (response is None or False), we return a fallback message to inform the user gracefully.

medium

Complete the code to call a backup API if the main API call fails.

Rest API

response = call_main_api()
if not response:
    response = [1]

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

💡 Hint

Common Mistakes

Calling the main API again instead of the backup.

Returning an error message instead of trying the backup.

If the main API call fails, we try the backup API to keep the service working.

3fill in blank

hard

Fix the error in the code to handle API failure gracefully.

Rest API

try:
    data = call_main_api()
except Exception:
    data = [1]

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

Acall_backup_api()

CNone

Dprint('Error')

💡 Hint

Common Mistakes

Re-raising the exception instead of handling it.

Setting data to None without fallback.

When the main API call raises an exception, we catch it and call the backup API to degrade gracefully.

4fill in blank

hard

Fill both blanks to create a dictionary with API data or fallback values.

Rest API

result = {
    "status": [1],
    "data": [2]
}

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

A"success"

Bcall_main_api()

CNone

D"failed"

Attempts:

3 left

💡 Hint

Common Mistakes

Using a function call directly instead of a string for status.

Setting data to a string instead of None.

We set status to 'success' and data to None as a fallback when no data is available.

5fill in blank

hard

Fill all three blanks to build a graceful degradation response dictionary.

Rest API

response = {
    "status": [1],
    "message": [2],
    "data": [3]
}

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

A"error"

B"Service temporarily unavailable"

CNone

D"success"

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'success' status when there is an error.

Providing data instead of None when service is down.

When the service fails, status is 'error', message explains the issue, and data is None.
