Lab 6 – Python

Q1) Read the following program

a, b = eval(input('Enter two numbers, separated by a comma: '))
if a > b:
    c = a + 4
    if b > 5:
        b = b - 2
elif a % 2 == 1:
    if b * 2 < 20:
        a = a + 3
    else:
         a = a - 1
    c = b - 2
else:
    c = -1
    if a == b:
        a *= 2
a = a + c
print(a, b, c)
