False

If both operands to the remainder operator (%) are positive, a divisor of n will produce a result in the range 1 to n.

True

If either or both operands to the division operator (//) are floating-point values, then the result will be a floating-point value.

Convert the user input to an integer.

Which of the following does the input function NOT do when it is called?

'#FFFFFF'

Which of the following hex strings represents the color white?

up and left (northwest)

Which way would the turtle be facing after executing the command turtle.setheading(135)?

down and right (southeast)

Which way would the turtle be facing after executing the following code? turtle.setheading(270) turtle.right(20) turtle.left(65)

8

If the current value of the variable count is 2, what value will be stored in count after the following line of code is executed? count += count * 3

6

If the current value of the variable num is 4, what value will be stored in num after the following line of code is executed? num += 2

False

The effect of the setheading depends on the current heading of the turtle.
