Consider a circle centered at the origin of two-dimensional coordinates and with radius 1. Now consider the quadrant perpendicular to the first region, that is, the region where both x and y values ​​are positive. Also consider a square with side 1 formed by the intersection of the coordinate axes and the lines x =1 and y =1. If we randomly select a point from this square, the probability that this point lies inside the quadrant is equal to the ratio of the area of ​​the quadrant to the area of ​​the square. The area of ​​a square is 1 × 1 and the area of ​​a quadrant is (pi / 4 × 1 × 1), so this probability is equal to pi / 4. Now we will simulate this with Python and calculate the value of the pi number , using this method.
