What is the output of the following snippet? def fun(x): global y y = x * x return y fun(2) print(y)

def fun(x):
    global y
    y = x * x
    return y
 
 
fun(2)
print(y)

• None
• 2
• 4
• the code will cause a runtime error

Explanation: Let’s analyze the code:

• the fun function is invoked with the integer 2 as its argument,
• the fun function makes the y variable a global variable, which can be used both inside and outside of the function,
• the operation y = 2 * 2 is performed, and the answer is the integer 4,
• the function returns the y variable value,
• the print(y) instruction prints the integer 4 on the console.
