Predict the output of the following code :
a = 10
y = 5
def myfunc():
y = a
a = 2
print("y =", y, "a =", a)
print("a + y =", a + y)
return a + y
print("y =", y, "a =", a)
print(myfunc())
print("y =", y, "a =", a)

Answer
The code raises an error when executed.
Working
In the provided code, the global variables a and y are initialized to 10 and 5, respectively. Inside the myfunc function, the line a = 2 suggests that a is a local variable of myfunc. But the line before it, y = a is trying to assign the value of local variable a to local variable y even before local variable a is defined. Therefore, this code raises an UnboundLocalError.
