1. Which is the best solution for this level?

A

B

C

2. Which is the correct solution for this level?

A

B

C

3. Which of the following is the correct Python code for these blocks?

A

from van import Van 
my_van = Van()

my_van.move_forwards(2) 
my_van.turn_right(2) 
my_van.move_forwards(1)

B

from van import Van 
my_van = Van() 

my_van.move-forwards() 
my_van.move-forwards() 
my_van.turn-right() 
my_van.turn-right() 
my_van.move-forwards()

C

from van import Van 
my_van = Van() 

my_van.move_forwards() 
my_van.move_forwards() 
my_van.turn_right() 
my_van.turn_right() 
my_van.move_forwards()

4. Which of the following is the correct Python code for these blocks?

A

from van import Van 
my_van = Van()  
while not at destination(): 
    my_van.move_fowards() 
    my_van.turn_left() 
    my_van.turn_right()

B

from van import Van 
my_van = Van() 
while not (my_van.at destination()): 
    my_van.move_fowards() 
    my_van.turn_left() 
    my_van.turn_right()

C

from van import Van 
my_van = Van()  

while not arrived: 
    my_van.move_fowards() 
    my_van.turn_left() 
    my_van.turn_right()

5. What is wrong with this Python code? You can choose more than one answer.

from van import Van
my_van = Van()

while not (my_van.at_destination())
    if my_van.is_road(‘FORWARD’)
        my_van.move_forwards()
    elif my_van.is_road(‘LEFT’)
        my_van.turn_left()
    else:
    my_van.turn_right()

• A - Missing colons after "while" and "if"

• B - “elif” is wrong and should be “else if”

• C - ‘FORWARD’ and ‘LEFT’ should be in double quotes

• D - my_van.turn_right() must be indented or the code will not run

6. What is wrong with this code? You can choose more than one answer.

from van import Van
v = van.Van()

while not (v.at_destination()):
    if v.is_road(‘FORWARD’):
        v.move_forwards()
    elif v.is_road(‘LEFT’) and not (v.is_road(‘FORWARD’)):
        v.turn_left()
    else if v.is_road(‘RIGHT’):
        v.turn_right()

• A - There is no need to check if there is no road forwards on the elif

• B - You cannot have a condition after and else

• C - The code must check if there is a dead end for all routes

• D - The van must be called ‘my_van’ and not ‘v’

7. What is the solution for this route?

What is the solution for this route?

A

from van import Van
my_van = Van()

for i in range(3): 
    my_van.turn_left() 
    my_van.turn_right() 
    my_van.turn_left() 
    my_van.turn_right() 
    my_van.turn_left() 
    my_van.turn_right()

B

from van import Van
my_van = Van()
for i in range(1): 
    my_van.turn_left() 
    my_van.turn_right() 
    my_van.turn_left() 
    my_van.turn_right() 
    my_van.turn_left() 
    my_van.turn_right()

C

from van import Van
my_van = Van()
for i in range(3): 
    my_van.turn_left() 
    my_van.turn_right()

D

from van import Van
my_van = Van()
for i in range(3): 
    my_van.turn_left() 
    my_van.turn_right() 
    i = i + 1

8. What is the purpose of a procedure?

• A - To make sure there are not errors in your code and the route works

• B - To allow you make choices between doing one thing or another

• C - To allow you to repeat a block of a code a certain number of times

• D - So you can write code once and call it whenever you need it
