python - 返回 Ajax 的多个项目

Question

我有这个 python 代码，用于搜索 eBay 以返回搜索字符串的结果。这些代码正确执行并返回我想要的结果，但仅当我使用 print() 函数时。我正在使用 json 将结果解析到 Flask 页面，使用 print() 仅打印到控制台，因此我使用了 return 但它没有给出所有结果，它只返回一项。

如何让代码返回所有结果并将其显示在我的 Flask 页面上？

我是 python 新手，这是我的第一个项目。我之前问过这个问题，并将代码升级到现在的样子，我一直在互联网上寻找解决方案，但我还没有找到任何解决方案。请有人帮助我编写一个代码，该代码将返回从搜索中获得的所有结果。

您的 python 代码仅返回 itemsFound 列表中的第一项，因为这就是您告诉它要做的事情:

 for key in itemsFound:
     return itemsFound[key]

...为什么不直接返回整个列表呢？就像这样

 return itemsFound
