在分隔符上分割一个Dataframe列并保留所有其他列

我有下面的“raw_input”数据框。如果你看一下“摘要”栏。有一个 分隔符“：”，我想上创建两个附加列，并添加到现有的数据帧在分隔符上分割一个Dataframe列并保留所有其他列

我想是“摘要”一栏分为两列（“工作包”和'任务'）

我可以使用下面的命令拆分分隔符。但我不知道如何添加/把它合并到现有的数据帧

split_data = pd.DataFrame(raw_input['Summary'].str.split(':',1).tolist(),columns=['Work Package','Task']) 

print(raw_input) 

     Key          Summary  Status          Description  Updated

3 XTBOW-422  Trade Migration: Reports (XTC vs XT2)   NaN            NaN 2017-05-19 



print(split_data) 

     Work Package        Task 
0  Data Mgmt Product Assesment and Selection 
1  Data Mgmt  Vendor > CIBC Implemention 
2 Trade Migration     PVs and Greeks

的raw_input'= pd.concat（[的raw_input，split_data]轴= 1）' –

谢谢！正是我需要的 – Karun

还有一个更简单的方法：

In [11]: df[['Work Package','Task']] = df['Summary'].str.split(':',1, expand=True) 

In [12]: df 
Out[12]: 
     Key          Summary            Status Description Updated \ 
0 XTBOW-310 Data Mgmt: Product Assesment and Selection In Analysis - To establish a provider for the... 2017-05-26  NaN 
1 XTBOW-420  Data Mgmt: Vendor > CIBC Implemention NaN - Integrate with Vendor to fetch Corporat... 2017-05-19  NaN 
2 XTBOW-421    Trade Migration: PVs and Greeks NaN - PVs and Greeks regression gap analysis ... 2017-05-19  NaN 
3 XTBOW-422  Trade Migration: Reports (XTC vs XT2) NaN           ... 2017-05-19  NaN 

     Work Package        Task 
0  Data Mgmt Product Assesment and Selection 
1  Data Mgmt  Vendor > CIBC Implemention 
2 Trade Migration     PVs and Greeks 
3 Trade Migration    Reports (XTC vs XT2)
