Question

Using a thread to control car racing. Compare the program with Exercise by setting the delay time to 10 in both programs. Which one runs the animation faster? Write a program that simulates car racing, as shown in Figure. The car moves from left to right. When it hits the right end. it restarts from the left and continues the same process. You can use a timer to control animation. Redraw the car with a new base coordinate (x, y), as shown in Figure. Also, let the user pause/resume the animation with a button press/release and increase/decrease the car speed by pressing the UP and DOWN arrow keys. The program displays a moving car. You can redraw a car with a new base point.

Explanation / Answer

# The following code provides some examples for using mathematical built-ins # Absolute value of 9 >>> abs(9) 9 # Absolute value of -9 >>> abs(-9) 9 # Divide 8 by 4 and return quotient, remainder tuple >>> divmod(8,4) (2, 0) # Do the same, but this time returning a remainder (modulo) >>> divmod(8,3) (2, 2) # Obtain 8 to the power of 2 >>> pow(8,2) 64 # Obtain 8 to the power of 2 modulo 3 ((8 **2) % 3) >>> pow(8,2,3) 1 # Perform rounding >>> round(5.67,1) 5.7 >>> round(5.67) 6.00
