Python -- Numbers and Inputs

Review the following lines of code:

x = 4

y = "Sally"

Identify each variable's data type

• x is an int

  y is an int

• x is an int

  y is a str

• x is a float

  y is a str

• x is a str

  y is an int

• x is an int

  y is a float

Based on the following lines of code...

x = 4

y = str(4) #casts y as a str

print(x)

print(y)

what will be displayed in the console?

TIP: single quotes have been added just to differentiate the str data types

• x

  y

• 4

  '4'

• 4

  4

• '4'

  4

Based on the following lines of code...

x = 5

y = float(5) #casts y as a float

print(x)

print(y)

what will be displayed in the console?

TIP: single quotes have been added just to differentiate the str data type

• x

  y

• '5'

  5.0

• 5

  5.0

• 5.0

Based on these variables:

player = "Johnny"

jerseyNum = 12

position = "Guard"

Which lines of code would produce the following console message (HINT: more than one option is correct):

Johnny wears #12 and plays Guard.

• print((player + " wears #" + (str)jerseyNum + " and plays " + position + "."))

• print(f'{player} wears #{jerseyNum} and plays {position}.')

• print(f'{Johnny} wears #{12} and plays {Guard}.')

• print({player} wears #{jerseyNum} and plays {position}.)

• print(player + " wears #" + jerseyNum + " and plays " + position + ".")

Based on the following lines of code...

x = 5

y = x * 3

print(y)

what will be displayed in the console?

• 15

• 5 * 3

• 555

• 333

Based on the following lines of code...

x = str(5) #casts x to a str

y = x * 3

print(y)

what will be displayed in the console?

• 15

• 5 * 3

• 555

• 333

We want to define a variable named age based on the number a user enters in the console.

Which of the following lines of codes would correctly create the variable?

(HINT: more than one option is correct)

• age = input("What's your age? ")

• age = num(input("What's your age? "))

• age = float(input("What's your age? "))

• age (f'What's your age? )

• age = int(input("What's your age? ")
