💡 Hint

Common Mistakes

Using incorrect event strings like 'Fire' (case sensitive)

Using unrelated events like 'flood' or 'earthquake'

The emergency handler should detect a fire event, so the correct event string is "fire".

💡 Hint

Common Mistakes

Setting the threshold too high like 10, missing moderate emergencies

Setting the threshold too low like 1, causing false alerts

The alert should be raised for emergencies with level 3 or higher, so the threshold is 3.

3fill in blank

hard

Fix the error in the emergency response function to correctly handle unknown events.

LLD

def emergency_response(event):
    match event:
        case "fire":
            print("Activate sprinklers")
        case "flood":
            print("Evacuate area")
        case _:
            print([1])

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

A"Unknown emergency! Stay alert."

BUnknown emergency! Stay alert.

CUnknown emergency

DNone

💡 Hint

Common Mistakes

Omitting quotes causing syntax errors

Using incomplete or incorrect messages

The print statement requires a string literal, so the message must be enclosed in quotes.

4fill in blank

hard

Fill both blanks to create a dictionary mapping emergency types to their response actions.

LLD

emergency_actions = {
    [1]: "Call fire department",
    [2]: "Shut off electricity"
}

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

A"fire"

B"flood"

C"power_outage"

D"earthquake"

💡 Hint

Common Mistakes

Using variable names instead of string keys

Mixing up emergency types and response actions

The dictionary keys should be emergency types as strings: "fire" and "power_outage".

5fill in blank

hard

Fill all three blanks to implement a function that logs emergency events with their severity and timestamp.

LLD

def log_emergency(event, severity):
    from datetime import datetime
    log_entry = {
        [1]: event,
        [2]: severity,
        [3]: datetime.now().isoformat()
    }
    print(log_entry)

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

A"event_type"

B"severity_level"

C"timestamp"

D"date"

💡 Hint

Common Mistakes

Using inconsistent or unclear key names

Using variable names instead of string keys

The dictionary keys should be descriptive strings: "event_type", "severity_level", and "timestamp".
