python - AttributeError: int 对象没有添加属性。在将预测保存到json格式文件夹的功能中

Question

我正在编写一个函数来将预测变量保存到 json 文件中。最初，该变量是 [1,0,1 ... 0, 0 1] 形式的 array.numpy16 类型。在函数代码中，我必须为数据添加一个 id。如何替换get参数或重写函数

import pandas
df = pandas.DataFrame(data=predictions)

def save_output(data, path):
    with open(path, mode="w") as file:
        for line in sorted(data, key=lambda x: int(x.get("idx"))):
            line["idx"] = int(line["idx"])
            file.write(f"{json.dumps(line, ensure_ascii=False)}\n")

   1 def save_output(data, path):
      2     with open(path, mode="w") as file:
----> 3         for line in sorted(data, key=lambda x: int(x.get("idx"))):
      4             line["idx"] = int(line["idx"])
      5             file.write(f"{json.dumps(line, ensure_ascii=False)}\n")

AttributeError: 'int' object has no attribute 'get'
