Following Python code has an expression with all integer values. Why is the result in floating point form?

a, b, c = 2, 3, 6
d = a + b * c/b
print(d)

What will following code print?

a = va = 3  
b = va = 3  
print (a, b)

What will following code print?

a = 3
b = 3.0
print (a == b)
print (a is b)

What will be the output, if input for both the statements is 5 + 4/2.

6 == input ("Value 1:")
6 == int(input ("value 2:"))
