    """
    如果page_number为20，则百度图片每页显示20张图片，因此对于flip形式每页会多缓存(60-20=40)张，index形式每页会多缓存(30-20=10)张，
    所以，请求4次的话:
        flip应该是 20 × 4 + (60 - 20) = 120张图片，而不是60×4 = 240
        index应该是 20 × 4 + (30 - 20) = 90张图片，而不是30×4 = 120
    示意图：

     120                           _|_

    说白了，就是获取了重复的图片
    可以通过调节page_number变量查看
    """
    all_pic_urls = []
    while 1:#死循环
        if times > total_times:
            break
        print("第{}次请求数据".format(times + 1))
        url=getPage(keyword, times, page_number, pic_type)#输入参数：关键词，开始的页数，总页数
        print(url)#打印链接
        onepage_urls= get_onepage_urls(url)#index是30个图片的链接,flip是60个
        times += 1#页数加1
        if onepage_urls != 0:
            all_pic_urls.extend(onepage_urls)#列表末尾一次性追加另一个序列中的多个值
            #print("将要下载的图片数量变为：{}".format(len(all_pic_urls)))
    print("下载的图片总量变为：{}".format(len(all_pic_urls)))


    download_pic(list(set(all_pic_urls)),keyword, save_path)#set去除重复的元素(链接)

效果如下（可以看到很多警告，也支持ctrl+鼠标访问函数和变量）：

4.我们点击F5，可以看到程序运行成功！！

是不是用这个IDE也很不错呢~
