for multi in json_file["shapes"]: TypeError: list indices must be integers or slices, not str

这个错误是因为在for循环中使用了错误的索引类型导致的。根据您提供的代码，错误发生在使用json_file["shapes"]这个列表时，而使用非整数或切片作为索引会导致TypeError: list indices must be integers or slices, not str的错误。为了解决这个问题，您需要确保在for循环中使用整数或切片作为索引。您可以修改代码如下：

for multi in range(len(json_file["shapes"])):
    # 这里是您的循环体

这样，您就可以使用整数索引来遍历json_file["shapes"]列表中的元素了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
