Output

25
None

Explanation

a, b = 12, 13 ⇒ assigns an initial value of 12 to a and 13 to b.
print (print(a + b)) ⇒ First print(a + b) function is called which prints 25. After that, the outer print statement prints the value returned by print(a + b) function call. As print function does not return any value so outer print function prints None.

x, y = 20, 60
y, x, y = x, y - 10, x + 10
print (x, y)


a, b = 12, 13  
c, b = a*2, a/2
print (a, b, c)


a, b, c = 10, 20, 30
p, q, r = c - 5, a + 3, b - 4
print ('a, b, c :', a, b, c, end = '')
print ('p, q, r :', p, q, r)
