2.16.4 Happy Face CodeHS Answers

The most common answer is:

happy = input (“Are you happy?:”)
if happy == (“Yes, yes”):
smileylove()
speed(0)
def smileylove():
penup()
setposition (0,-100)
pendown()
color(“yellow”)
begin_fill()
circle(100)
end_fill()
color(“black”)
penup()
pensize(1)
setposition(-25,25)
for i in range (2):
begin_fill()
circle(5)
end_fill()
penup()
forward(50)
pendown()
penup()
setposition (-50,-25)
left(270)
pendown()
circle (50, 180)
penup()
smileylove()

To create a program that draws a smiley face based on user input, we need to adjust the structure of the code for proper execution. The main adjustments include:

1. Moving the function definition to the beginning, before it’s called.
2. Ensuring the input() function works correctly for checking if the user is happy.
3. Correcting the syntax for string literals in input() and color() functions.
4. Fixing the loop that draws the eyes to ensure both eyes are filled correctly.
5. Removing the recursive call to smileylove() at the end of its definition to prevent infinite recursion.

Here’s the corrected and optimized version of your code:

import turtle

def smileylove():
    turtle.speed(0)  # Set the drawing speed to the fastest
    turtle.penup()
    turtle.setposition(0, -100)
    turtle.pendown()
    turtle.color("yellow")
    turtle.begin_fill()
    turtle.circle(100)
    turtle.end_fill()
    
    # Draw eyes
    turtle.color("black")
    positions = [(-25, 50), (25, 50)]  # Positions for the eyes
    for position in positions:
        turtle.penup()
        turtle.goto(position)
        turtle.pendown()
        turtle.begin_fill()
        turtle.circle(5)
        turtle.end_fill()
    
    # Draw smile
    turtle.penup()
    turtle.goto(-50, 0)
    turtle.pendown()
    turtle.setheading(-60)  # Orient the turtle to start the smile
    turtle.circle(50, 120)  # Draw the smile

happy = input("Are you happy? (Yes/No): ")
if happy.lower() == "yes":
    smileylove()

turtle.done()

This version asks the user if they are happy, and if the response is “Yes” (case-insensitive), it draws a smiley face. The face is yellow with two black eyes and a smile. The adjustments ensure that the program correctly interprets the user’s input and draws the smiley face accordingly.
