熊猫根据列将两行合并为一行

Question

我有2行看起来像这样，

------------------------------
DealName | Target | Acquirer |
-----------------------------
ABC-XYZ  | ABC    | None     |
------------------------------
ABC-XYZ  | None   | XYZ      |
------------------------------

我希望将它们合并为一个：

------------------------------
DealName | Target | Acquirer |
-----------------------------
ABC-XYZ  | ABC    | XYZ      |
------------------------------

不确定如何在Pandas中完成此操作。任何指针将不胜感激！预先感谢

Answer 1

IIUC

df.replace('None','').groupby('DealName',as_index=False).agg(''.join)
Out[25]: 
  DealName Target Acquirer
0  ABC-XYZ    ABC      XYZ
