What will be the output of following Python code?

x, y = 4, 8
z = x/y*y 
print(z)

Make change in the expression for z in the Python code given below so that the output produced is zero. You cannot change the operators and order of variables. (Hint. Use a function around a sub-expression)

x, y = 4, 8
z = x/y*y 
print(z)

Consider the following code segment:

a = input()
b = int(input())
c = a + b 
print(c)

When the program is run, the user first enters 10 and then 5, it gives an error. Find the error, its reason and correct it

Consider the following code segment:

a = input("Enter the value of a:")
b = input("Enter the value of b:")
print(a + b)

If the user runs the program and enters 11 for a and 9 for b then what will the above code display?
