Gauss Circle Problem

Can do better without two loops :-|

latticePoints = 0
radius = 3.2
mod = int(radius) + 1

def isInCircle(x, y):
    return x*x + y*y <= radius*radius

def calc(x, y):
    global latticePoints
    if x == 0 and y == 0:
        latticePoints = latticePoints + 1
        print((x, y))
    elif x == 0 and y != 0:
        latticePoints = latticePoints + 2
        print((x, y),(x, -y))      
    elif x != 0 and y == 0:
        latticePoints = latticePoints + 2
        print((x, y),(-x, y))      
    else :
        latticePoints = latticePoints + 4
        print((x, y), (-x, -y), (x, -y), (-x, y))          

for i in range(mod) :
    for j in range(mod) :
        if(isInCircle(i,j)):
            calc(i,j)
 
print(latticePoints)
