Answer 1

Q10) Let us analyze the turtles movement for each value of i.

For i ==0 : Second condition is true , turtle pen remains up but turtle turns 90 degrees clockwise and finally faces downward. Turtle writes nothing.

For i==1: First condition is true. Turtle pen is down. It is already facing downwards and thus moves forward 100 units drawing a straight line.

For i==2: None of the condition is true. Nothing happens.

For i==3: Both conditions are true , due to the first condition turtle again moves 100 units downward because direction has remained same. Due to the second condition , pen is lifted and the turtle turn 90 degress clockwise. the turle is thus finally facing west.

So overall turtle draws a straight line of 200 units in length and finally faces westwards. Option (A) is correct.

Q11 A) Please read comments for clarification,

import turtle

def drawLine(turtle , length):
   turtle.down() #puts the turltes pen down if it was not down originally
   turtle.forward(length)    #moves the turtle length units forwars to draw a line

s= turtle.Screen()
t = turtle.Turtle()
drawLine(t,100)

Q11 B) Please read the comments for clarification.

import turtle

def spikes(numlines , lengthIncr , angle):
   # creating a turtle and screen
   s = turtle.Screen()
   t = turtle.Turtle()

   # put the turtle pen down and initiate the length of firstline
   t.down()
   lineLength = lengthIncr

#Loop to draw each line one by one

   for i in range(numlines):
       t.forward(lineLength) #move the turtle forward to draw a line
       t.backward(lineLength) #bring back the turtle to starting point
       lineLength += lengthIncr #increment line length for the next line
       t.right(angle) #turn the direction of turtle by angle degrees clockwise
