Question

我正在学习一个教程：https://youtu.be/PZkuTzeRE2U?t=682 然后我得到一个KeyError: 722。

我试图找到在线含义，并且我的代码与本教程似乎相同。我将添加更多代码，仅告诉我您需要查看和显示错误

我已经检查了一百次视频，并尝试搜索该错误代码，但是我无法找到任何实际答案。我非常感谢您的帮助，因为我非常投入这项练习

问题似乎出在(price[end+1:end+16] - price[end])

if harmonics[j] == 1:
    pips += 1000*(price[end+1:end+16] - price[end])
elif harmonics[j] == -1:
    pips += 1000*(price[end] - price[end+1:end+16])

我希望条形图会出现，但是我得到了
