分别使用python和java编写金字塔图形

public class Ch1_1 {
    public static void main(String[] args) {
        int n = 5;
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= n - i; j++) {
                System.out.print(" ");
            }
            for (int k = 1; k<=(2*i-1);k++){
                System.out.print("*");
            }
            System.out.println("");
        }
    }
}

n=5
for i in range(1,n+1):
    print((n-i)*" "+(2*i-1)*"*")
