What is the output of the following snippet if the user enters two lines containing 2 and 4 respectively? x = int(input()) y = int(input()) x = x // y y = y // x print(y)

What is the output of the following snippet if the user enters two lines containing 2 and 4 respectively?

x = int(input())
y = int(input())
 
x = x // y
y = y // x
 
print(y)

• 8.0
• the code will cause a runtime error
• 2.0
• 4.0

Explanation: Let’s analyze this example:
– the x variable is assigned the integer value of 2 (2 is inputted by the user, converted to a string by the input() function, and then converted to an integer by the int() function)
– the y variable is assigned the integer value of 4 (4 is inputted by the user, converted to a string by the input() function, and then converted to an integer by the int() function)
– an operation is performed resulting in the x variable being assigned the value of 0 (2 // 4=0)
– an operation is being performed, but a ZeroDivisionException is raised, because the // operator cannot accept 0 as its right operand. The program is terminated.

What is the output of the following snippet if the user enters two lines containing 2 and 4 respectively?

x = int(input())
y = int(input())
 
x = x / y
y = y / x
 
print(y)

• the code will cause a runtime error
• 2.0
• 8.0
• 4.0

Explanation: Let’s analyze this example:

the x variable is assigned the integer value of 2 (2 is inputted by the user, converted to a string by the input() function, and then converted to an integer by the int() function)
the y variable is assigned the integer value of 4 (4 is inputted by the user, converted to a string by the input() function, and then converted to an integer by the int() function)
an operation is performed resulting in the x variable being assigned the value of 0.5 (2 / 4 = 0.5)
an operation is performed resulting in the y variable being assigned the value of 8.0 (4 / 0.5 = 8.0)
the value assigned to the y variable (8.0) is printed to the screen.
