Pandas 根据列将两行合并为一行

Pandas Merge two rows into a single row based on columns

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！提前致谢

IIUC

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