Need help translating this java code to python

public class LeibnizFormula {

public static void main(String[] args) {

int count = 999999999;

double pi = 0;

double denominator = 1;

for (int x = 0; x < count; x++) {

if (x % 2 == 0) {

pi = pi + (1 / denominator);

} else {

pi = pi - (1 / denominator);

}

denominator = denominator + 2;

}

pi = pi * 4;

System.out.println(pi);

}

}
