部分一個CSV文件(「data.csv」)我必須處理,看起來是這樣的:合併行的數據幀
parent_id,parent_name,Type,Companyname,Custsupid,Streetaddress
3,Customer,,,C0010,
3,Customer,A,,,
3,Customer,,ACE SYSTEMS,,
3,Customer,,,,Straat 10
7,Customer,,,Q8484,
7,Customer,B,,,
7,Customer,,XYZ AUTOMAT,,
7,Customer,,,,Laan 99
要將此文件導入到一個數據幀我做的:
DF = pd.read_csv( 'data.csv')fillna( '')
這導致:
------------------------------------------------------------------
| |parent_id|parent_name|Type|Companyname|Custsupid|Streetaddress|
------------------------------------------------------------------
|0|3 |Customer | | |C0010 | |
|1|3 |Customer |A | | | |
|2|3 |Customer | |ACE SYSTEMS| | |
|3|3 |Customer | | | |Straat 10 |
|4|7 |Customer | | |Q8484 | |
|5|7 |Customer |B | | | |
|6|7 |Customer | |XYZ AUTOMAT| | |
|7|7 |Customer | | | |Laan 99 |
------------------------------------------------------------------
不過,我想結束了,是datafr這個看起來像這樣:
------------------------------------------------------------------
| |parent_id|parent_name|Type|Companyname|Custsupid|Streetaddress|
------------------------------------------------------------------
|0|3 |Customer |A |ACE SYSTEMS|C0010 |Straat 10 |
|1|7 |Customer |B |XYZ AUTOMAT|Q8484 |Laan 99 |
------------------------------------------------------------------
我已經嘗試與df.groupby等,但我不能產生所需的結果。
有沒有辦法用熊貓數據框來實現這一點?
