GWC Week 5 Review

Tracing Code

Operators

Write Some Code!

100

What does this code print out?

is_sunny = True

print(not is_sunny)

False

100

What is the difference between the operators <= and <?

<= will return true if the LHS is less than OR equal to the RHS, but < will only return true if the LHS is strictly less than the RHS

100

Write one line that creates a screen turtle

<screen name> = turtle.Screen()

200

What does this code print out?

x = 5

y = 0

print(x < 6 and y > 0)

False

200

What is the difference between these two operators: == and =

== checks if the RHS and LHS are equal (compares), while the = sets the value of a variable. BONUS: what is another name for =?

200

Write one line that sets the pen size of a turtle, named Bob, to 8.

bob.pensize(8)

300

What does this code print out?

“No rain today”

“It is raining today”

300

When do the AND, OR, and NOT operators return True? (1 answer per operator)

AND- returns True if BOTH the RHS and LHS are True

OR- returns True if AT LEAST ONE of the RHS OR the LHS is True

NOT- returns True when put in front of a False value

300

Write THREE lines that will draw a square. (Assume a turtle named tim already exists in the program)
