Given the following line of code

x = 5 + 8.0

• int

• float

• str

• Python is loosely typed, so we don't know.

What are the results of the following calculations?

9//2          9/2

• 4 & 4

• 4 & 4.5

• 4.5 & 4

• none of the above

What value is stored in x after the following line of code?

x = (4 + 2*4 - 3**2)//2

(a)  

What value is stored in z after the following code is run?

x = 10

y = 5

z = x/y + x*y - x

(a)  

What value will b have after the following code is run?

a = 5

b = 8

a = b

b = a

(a)  

An import statement:

• 
  makes a collection of functions and/or constants available to us to use in our code.

•  

  copies data from one variable into another variable.

• loads data from a data file.

• should be located at the top of our program.

• 
  asks the user to enter input, and pauses our program until the input is received.

How should the blank in the following line of code be filled to print

one plus two is three

?

print("_______________".format(first = "one", second = "two", answer = "three"))

• {"one"} plus {"two"} is {"three"}

• {one} plus {two} is {three}

• {"first"} plus {"second"} is {"answer"}

• {first} plus {second} is {answer}

• {1} plus {2} is {3}

print(" (a)   ".format("Tuesday", "Monday", "today", "tomorrow"))

Fill in the blank so that the above code prints

If today is Monday then tomorrow will be Tuesday.

Fill in the blank so that pi is printed to occupy 8 characters, with 3 decimal places.

import math
print("{ (a)   }".format(math.pi))

Fill in the blank so that 123.456 is printed to occupy 12 characters, with 5 decimal places.

import math
print("{ (a)   }".format(theAnswer = 123.456))
