What is the output of the following snippet? x = 1 y = 2 z = x x = y y = z print(x, y)

x = 1
y = 2
z = x
x = y
y = z
print(x, y)

• 2 1
• 1 1
• 1 2
• 2 2

Explanation: Let’s analyze this example:

– the value 1 is assigned to variable x, and variable x is initiated (so x = 1)
– the value 2 is assigned to variable y, and variable y is initiated (so y = 2)
– the value assigned to variable x is assigned to variable z, and variable z is initiated (so z = 1)
– the x variable is assigned the value which is assigned to variable y (so x = 2)
– the y variable is assigned the value which is assigned to variable z (so y = 1)
– the values ssigned to variables x and y are now printed, giving the following output: 2 1 (note: the print() function separates the outputted values with a whitespace)
