Booleans

100

What is a Boolean?

A variable that can be either True or False

200

Will this code create a Boolean variable?

broughtSnack = true

NO - the first letter of the value must be capitalized:

e.g. True 

e.g. False

300

Will this code cause an error? If yes, why?

broughtSnack = True

print(“Brought snack?” + broughtSnack)

YES - we cannot concatenate a String and a Boolean

400

Fix this code:

broughtSnack = True

print(“Brought snack?” + broughtSnack)

print(“Brought snack?” + str(broughtSnack))

If Statements

100

What does an if statement do?

Allows a program to behave differently based on circumstances

200

In the following code, what type must condition evaluate to?

A BOOLEAN

300

What will print?

raining = True

if raining:

  print("Make sure to bring an umbrella!")

else:

  print("You do not need an umbrella today.")

Make sure to bring an umbrella!

400

Find the errors (there are two):

if hasDog

print("Go walk")

else:

    print("You don't need a walk")

On line 1, missing a colon

Line 2 is missing an indent

500

What will print?

favoriteColor = "blue"

if favoriteColor == "blue":

    if favoriteColor != "yellow":

         print("must be blue")

elif favoriteColor == "blue":

    if favoriteColor != "yellow":

          print("I like purple")

else:

     if favoriteColor == "blue":

        print("blue is the best")

Must be blue

Float Rounding

100

Will val be True or False?

val = 0.0037 / 100 == 0.000037

False

200

Why should you use round() when you compare two numbers of type float?

Sometimes float numbers can be rounded in unexpected ways based on how Python computes them. Therefore, it is best to use round() in order to make sure both numbers are rounded the same way

300
