如何使用Python将数据打印到CSV

Question

我创建了一个python程序来提供diff文件。想知道将差异的结果发送到.csv的最佳方法是什么

这是我的代码，

import difflib

file1 = "swiss1.csv"
file2 = "swiss2.csv"

diff = difflib.ndiff(open(file1).readlines(),open(file2).readlines())

for line in diff:
    if line[0] in ["+", "-"]:
        print line

我打算将它打印到CSV文件，而不是打印到终端。思考？

Answer 1

final ImageButton layerButton = (ImageButton) findViewById(R.id.layers);
final PopupMenu popup = new PopupMenu(MapsActivity.this, layerButton);
popup.getMenuInflater().inflate(R.menu.toolbar_menu, popup.getMenu());

layerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            //Here
            popup.show();

            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                @Override
                public boolean onMenuItemClick(MenuItem item) {

                    handleClicksOnCheckBoxes(item);

                    return true;

                }

            });

            //And here
            popup.show();


        }
    });
