💡 Hint

Common Mistakes

Choosing 25 kg which is the Nano drone limit, not the max allowed.

The DGCA allows drones up to 500 kg in the 'Nano' to 'Large' categories. Here, 500 kg is the upper limit for certain drone classes.

Complete the code to check if drone registration is required based on weight.

💡 Hint

Common Mistakes

Using '<' which would register drones under 250 grams incorrectly.

Drones weighing 250 grams or more must be registered with DGCA.

Fix the error in the code that checks if drone flight is allowed in restricted zones.

Drone Programming

if flight_zone == 'restricted' and drone_category [1] 'Nano':
    allow_flight = False

D==

💡 Hint

Common Mistakes

Using '==' which would block Nano drones incorrectly.

Flight is not allowed in restricted zones unless the drone is a Nano category (which is allowed). So we check if drone_category is not 'Nano'.

4fill in blank

Fill both blanks to create a dictionary comprehension that maps drone categories to their max weight limits if the weight is less than 500 kg.

Drone Programming

weight_limits = {category: [1] for category, weight in drone_data.items() if weight [2] 500}

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

💡 Hint

Common Mistakes

Using '>' which would select weights above 500 kg incorrectly.

The comprehension maps categories to their weights only if the weight is less than 500 kg.

Fill all three blanks to create a filtered dictionary of drones with registration required and weight over 250 grams.

Drone Programming

registered_drones = { [1]: [2] for [3], [2] in drones.items() if [2] >= 250 }

💡 Hint

Common Mistakes

Using inconsistent variable names causing errors.

The dictionary keys are drone IDs and values are weights. We iterate over drone_id and weight pairs, filtering weights >= 250 grams.

Practice

1. Which of the following is a mandatory requirement for flying a drone in India according to DGCA rules?

easy

A. Flying in restricted no-fly zones

B. Flying above 400 feet without permission

C. Registering the drone before flight

D. Ignoring the drone weight limits

Solution

1. Step 1: Understand DGCA registration rule

   DGCA mandates that all drones must be registered before flying in India.

2. Step 2: Check other options against DGCA rules

   Flying above 400 feet or in no-fly zones is prohibited without permission, and ignoring weight limits is not allowed.

3. Final Answer:

   Registering the drone before flight -> Option C

4. Quick Check:

   Registration is mandatory = C [OK]

Hint: Remember: Registration is the first step before flying [OK]

Common Mistakes:

• Assuming flying above 400 feet is allowed
• Ignoring no-fly zone restrictions
• Thinking weight limits don't matter

2. Which Python code snippet correctly checks if a drone's altitude is within the DGCA allowed limit of 400 feet?

easy

A. if altitude <= 400:
print('Safe to fly')

B. if altitude < 400:
print('Safe to fly')

C. if altitude >= 400:
print('Safe to fly')

D. if altitude > 400:
print('Safe to fly')

Solution

1. Step 1: Understand altitude limit condition

   DGCA allows flying up to 400 feet inclusive, so altitude <= 400 is correct.

2. Step 2: Analyze each condition

   if altitude <= 400: print('Safe to fly') uses <= 400, which includes 400 feet. if altitude < 400: print('Safe to fly') excludes 400 feet, the other options allow unsafe altitudes.

3. Final Answer:

   if altitude <= 400:\n print('Safe to fly') -> Option A

4. Quick Check:

   Altitude must be at most 400 = B [OK]

Hint: Use <= 400 to include max allowed altitude [OK]

Common Mistakes:

• Using < 400 excludes exactly 400 feet
• Using >= or > allows unsafe altitudes
• Confusing comparison operators

3. What will be the output of this Python code snippet checking drone weight compliance?

weight = 2.5  # in kg
if weight <= 2:
    print('Light drone')
elif weight <= 25:
    print('Medium drone')
else:
    print('Heavy drone')

medium

A. Light drone

B. Medium drone

C. Heavy drone

D. No output

Solution

1. Step 1: Check weight against conditions

   Weight is 2.5 kg, which is not <= 2 but is <= 25.

2. Step 2: Determine which print executes

   Since 2.5 <= 25, the 'Medium drone' print statement runs.

3. Final Answer:

   Medium drone -> Option B

4. Quick Check:

   2.5 kg fits medium drone category = A [OK]

Hint: Check conditions top to bottom; first true runs [OK]

Common Mistakes:

• Assuming 2.5 kg is light drone
• Ignoring elif condition
• Thinking else runs for 2.5 kg

4. Identify the error in this Python code snippet that checks if a drone is flying in a no-fly zone:

no_fly_zones = ['airport', 'military_base']
drone_location = 'airport'
if drone_location = no_fly_zones:
    print('Drone in no-fly zone!')

medium

A. Using '=' instead of '==' in the if condition

B. Incorrect list syntax for no_fly_zones

C. Missing colon ':' after if statement

D. Wrong variable name drone_location

Solution

1. Step 1: Check the if condition syntax

   The code uses '=' which is assignment, not comparison. It should be '==' or 'in'.

2. Step 2: Understand correct membership check

   To check if drone_location is in no_fly_zones, use 'if drone_location in no_fly_zones:'. Using '=' causes syntax error.

3. Final Answer:

   Using '=' instead of '==' in the if condition -> Option A

4. Quick Check:

   Use '==' or 'in' for comparison, not '=' [OK]

Hint: Use '==' or 'in' for comparisons, '=' is assignment [OK]

Common Mistakes:

• Using '=' instead of '==' or 'in'
• Confusing assignment with comparison
• Not checking membership properly

5. You want to write a Python function to check if a drone flight is legal under DGCA rules. The drone must be registered, fly below 400 feet, and not be in a no-fly zone. Which function correctly implements these checks?

hard

A. def is_legal(registered, altitude, location):
if registered and altitude > 400 and location not in ['airport', 'military_base']:
return True
return False

B. def is_legal(registered, altitude, location):
if registered or altitude < 400 or location in ['airport', 'military_base']:
return True
return False

C. def is_legal(registered, altitude, location):
if not registered and altitude > 400 and location in ['airport', 'military_base']:
return True
return False

D. def is_legal(registered, altitude, location):
if registered and altitude <= 400 and location not in ['airport', 'military_base']:
return True
return False

Solution

1. Step 1: Analyze legal conditions

   Drone must be registered, altitude <= 400, and location not in no-fly zones.

2. Step 2: Check each option's logic

   def is_legal(registered, altitude, location): if registered and altitude <= 400 and location not in ['airport', 'military_base']: return True return False uses 'and' for all conditions correctly. Others use 'or' or wrong comparisons allowing illegal flights.

3. Final Answer:

   def is_legal(registered, altitude, location):\n if registered and altitude <= 400 and location not in ['airport', 'military_base']:\n return True\n return False -> Option D

4. Quick Check:

   All conditions must be true = A [OK]

Hint: Use 'and' to combine all legal conditions [OK]

Common Mistakes:

• Using 'or' instead of 'and' allowing illegal flights
• Wrong altitude comparison signs
• Incorrect no-fly zone membership check
