Which is the correct way to declare a variable named "my_var" and assign it to the integer value 5 in python?

• int my_var = 5;

• variable my_var = 5;

• my_var = 5

• my_var = 5.0

What is the value of my_var1 at the end of the block of code.

my_var1 = 5                   

my_var2 = "string"    

my_var1 = my_var2 

my_var2 = 9.0              

• 5

• "string"

• 9.0

• This code fragment has errors

What is is the output of the following code:

example_variable = ["hello", "world"]

print(type(example_variable))               

• <class 'str'>

• <class 'list'>

• <class 'int'>

• <class 'character'>

What is the value of the expression:

(5 // 2) ** 3

• 4

• 6

• 8

• 15.625

What is the value of "x" at the end of this code block

var x = "hello"

x += ", world"

• "hello"

• "hello, world"

• ", world"

• Error

What is the name of the function in the following code block:

def computation(x,y,z):                        

constant = 5                             

return constant * (x+y+z)

• def

• computation

• x,y,z

• constant

What is the value of "x" after the following code:

count = 0                    

x = 0                             

while count < 5:      

x +=2           

count += 1

• 0

• 5

• 10

• 20

What is the error in the following while loop:

sum = 0                        

count = 10                      

while max >= 0:           

sum += max

• max is never changed so the loop will never end

• Assigning a variable in a loop is an error

• there is no closing "end" statement on the while loop

• There are no errors, this code will run and compelte

What is the output of this code block:

x = 5                      

if x <= 5:               

print("1")      

if x <= 6:               

print("2)

else:                       

print("3")

• 1

• 2

• 1

  2

• 1

  2

  3

What is the value of "x" after this code block:

x = [1,2,3]      

x.append(4)

x.pop(0)        

• [1,2,3,4]

• [1,2,3]

• [2,3,4]

• [1,2,3,4,0]
