在本地计算机上使用python读取s3存储桶中的数据

Question

我想将数据从s3存储桶读取到本地计算机，并在带有python的jupyter笔记本中使用它。我尝试了以下代码，但失败了：

import android.content.Context;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.toolbox.Volley;

public class MySingleton {
    private static MySingleton mInstance;
private static Context mCtx;
private RequestQueue mRequestQueue;

private MySingleton(Context context) {
    mCtx = context;
    mRequestQueue = getRequestQueue();
}

public static synchronized MySingleton getInstance(Context context) {
    if (mInstance == null) {
        mInstance = new MySingleton(context);
    }
    return mInstance;
}

private RequestQueue getRequestQueue() {
    if (mRequestQueue == null) {
        // getApplicationContext() is key, it keeps you from leaking the
        // Activity or BroadcastReceiver if someone passes one in.
        mRequestQueue = Volley.newRequestQueue(mCtx.getApplicationContext());
    }
    return mRequestQueue;
}

public <T> void addToRequestQueue(Request<T> req) {
    getRequestQueue().add(req);
}
