Pandas应用错误我有一个Pandas数据框，包含以下各列

col = ["File_Path", "Function_Body", "Prediction", "Line_Number"]

我在列函数体上应用get_prediction（）函数，它返回三个值
1.列表（预测）：例如[1,1,0,0,0]
1.列表（置信度）：例如[64.000, 88.000,0,0,0]
1.列表的列表（前5个标记及行号）：[['int', 5], ['ret', 6],['char', 5],['sum', 4],['i', 2]]
下面的代码段对于一个数据集运行良好，但对于另一个数据集却出现错误。

final_df["Prediction"],  final_df["Confidence"], final_df["Tokens"] = zip(*final_df["Function_Body"].apply(lambda x:get_prediction(x)))

错误：

File "nginx_fast.py", line 404, in <module>
    final_df["Prediction"],  final_df["Confidence"], final_df["Tokens"] = zip(*final_df["Function_Body"].apply(lambda x:get_prediction(x)))

我在return语句之前检查了返回值的形状和类型，它看起来很好。
