将包含Dataframe作为列表项的整个列表转换为单个Dataframe，即python3.6

Question

我在多处理任务中使用以下脚本：

Data_List = pool.map(self.Get_Series_Data, Series_Id_List)

方法“self.Get\u Series\u Data”生成数据帧，“pool.map”作为列表存储在数据列表中

[
Date      Value    Series_Id
0 1985-01-01  106.92593  CANEPUINDXM
1 1985-02-01  114.69938  CANEPUINDXM,

Date      Value    Series_Id

我要将此列表项（包含数据帧）转换为单个数据帧

Answer 1

我认为这应该管用：-

single_dataframe = pd.concat(data_list)
