HackerRank Sherlock and Squares problem solution

In this HackerRank Sherlock and Squares problem, you need to complete the squares function that should return an integer representing the number of square integers in the inclusive range from a to b.

Problem solution in Python programming.

t = int(input())

for i in range (0,t):
	count = 0
	a,b = [int(j) for j in input().strip().split()]
	square1 = a ** (.5)
	if (square1 != int(square1)):
		a1 = int(square1) + 1
	else:
		a1 = int(square1)
	square2 = b ** (.5)
	b1 = int(square2)
	count = b1 - a1 +1
	print(count)
