Question

23. Given a = 5, b = 4, c = 2, evaluate the following:

a) a//c

b) a % b

c) b **c

d) b *= c

27. Given the following

var_1 = 2.0

var_2 = "apple"

var_3 = 'orange'

var_4 = 4

Predict the output of the following statements or indicate that there would be an error.

a) print (var_1)

b) print (var_2)

c) print ("var_3")

d) print (var_1 / var_4)

e) print (var_4 + var_3)

f) print (var_2 + var_3)

Answer 1

23. Given a = 5, b = 4, c = 2
(a)
a//c - Floor division or Integer division which returns the integer without any decimal
5//2 = 2

(b) a % b - Returns the remainder when a is divided by b
5%4 = 1

(c) b **c - Returns the result when b is raised to the power of c
4**2 = 4^2 = 16

(d) b *= c - Returns the result when b is multiplied by c and the result is stored back in b
b= b*c = 4*2 = 8

27. Given the following

var_1 = 2.0
var_2 = "apple"
var_3 = 'orange'
var_4 = 4

(a) print (var_1) - prints the value stored in variable var_1 i.e 2.0
2.0

(b) print (var_2) - prints the value stored in variable var_2 i.e "apple"
apple

(c) print ("var_3") - print the string "var_3"
var_3

(d) print (var_1 / var_4) - performs floating-point divison and prints the result obtained when var_1 is divided by var_4 i.e 2.0/4 = 0.5
0.5

(e) print (var_4 + var_3) - generates type error since there is no "+" operator specified for operand types "int" and "str"
TypeError: unsupported operand type(s) for +: 'int' and 'str'

(f) print (var_2 + var_3) - performs string concatenation of var_2 and var_3 and prints the result of this concatenation i.e "apple"+'orange' = appleorange
appleorange
