【问题描述】：
所以我的代码有问题，我试图从 python 将值返回到我的 HTML。现在我正在使用一个包含 190 多种产品的 API，它们都存储在 itemName、buyPrice、sellPrice 等变量中。
例如，如果我用 HTML 编写：
{{ itemName }}
我写了很多次，然后使用： return ("index.html", itemName=itemName)
它当然会一遍又一遍地返回相同的名称，现在我希望它返回第一个名称，然后是第二个名称，然后是第三个名称，依此类推，买入和卖出价格相同。
名称位于名为“产品”的数组中，价格等位于我使用 request.get(...) 的 API 中。我的代码在下面

【问题讨论】：
-
你必须在你的 index.html 中做。你能显示html文件吗？
-
我没有和以前一样的 HTML，尝试进行更改但没有运气，这就是它在正文标签内部的样子。 pastebin.com/eufThtLW（在那里更容易阅读）顺便说一句，如果有帮助，我会使用 Jinja。
