python中如何将九九乘法表输出到txt文件？

public static void main(String[] args) throws IOException {
// 文件的路径
String pathname = “D:/cool/cool.txt”;
//获取文件
File file = new File(pathname);
// 写入文件
BufferedWriter writer = new BufferedWriter(new FileWriter(file));
for (int i = 1; i <= 9; i++) {
for (int j = 1; j <= i; j++) {
writer.write(i+""+j+"="+ij+"\t"); // 写入
writer.flush(); //刷新
}
writer.newLine(); // 换行
}
writer.close(); // 关闭写入
System.out.println(“写入成功！”);
}
