python中如何将九九乘法表输出到txt文件中？

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！”);

}
