What is Python's equivalent of Java's standard for-loop?

I'm writing a simple algorithm to check the primality of an integer and I'm having a problem translating this Java code into Python:

for (int i = 3; i < Math.sqrt(n); i += 2) {
    if (n % i == 0)
        return false;
}

So, I've been trying to use this, but I'm obviously skipping the division by 3:

i = 3
while (i < int(math.sqrt(n))):
    i += 2  # where do I put this?
    if (n % i == 0):
        return False
