a- def print_hello()    print('hello')

b- def hello():    print('hello')

c- defun hello    print('hello')

d- defun print_hello:    print('hello')

6) Which of the following functions would return the smaller of the two parameters if the first parameter is evenly divisible by three and zero, otherwise?

a- def smaller(x, y):    if x % 3 != 0:        return 0    else:        return min(x, y)

9) Which of the following is the best reason for dividing a program into functions?

- Dividing a large program into functions allows debugging the parts one at a time and then assemble them into a working whole

- By subdividing a program into multiple functions, it makes the program more secure

- sing multiple functions reduces the possiblity of code reuse

- Increasing the number of functions in a program greatly increases the speed of the program

a-  def average(x, y):    print(y + x / 2)

b- def average(x, y):    avg = x + y    print(avg)

c- def average(x, y):     print(x + y /2)

d- def average(x, y):    print((x + y) / 2)
