我有一个像这样的熊猫数据框:
Index | Line Item | Insertion Order | Creative Type
_________________________________________________________________________________________________
1 | blbl 33 dEs '300x600' Q3 | hello 444 | UNKNOWN
2 | QQQ4 Hello trueview Apple | something 68793274 | UNKNOWN
3 | A useless string | pre-roll Video <10 tttt 89 CASIO | UNKNOWN
4 | Something not in dict | Neither here | UNKNOWN
还有这样的字典:
dct = {
'RISING STARS': ['300x600', 'Box 300x600', '300x250', 'Box 300x250', 'Classic Skin', 'Main Banner', 'Half Banner', 'Masthead', 'Push Bar', 'Strip', 'In Image', 'Mix formati display rising'],
'VIDEO': ['trueview', 'Video Banner', 'Video in Picture', 'Videobox', 'Mid-roll Video', 'Pre-roll+Inread', 'Pre-roll Video <10', 'Pre-roll Video =10', 'Pre-roll Video =15', 'Pre-roll Video =20', 'Pre-roll Video =30' ,'Pre-roll Video >30','Inread / Intext / Outstream','Mix formati video','Post-roll Video','Inread XXX (Landscape/Vertical/Square)', 'Pre-roll Video Sponsored Session' ,'Pre-roll Video Viewmax' ,'Pre-roll Video Takeover']}
我想替换我的数据帧的创意类型列中的值:如果该列的值Line Item或Insertion Order与字典的值匹配,则该列的相应行Creative Type应采用字典键的名称。如果没有匹配,则列广告素材类型的相应行应接收值NaN。
预期输出是:
Index | Line Item | Insertion Order | Creative Type
_________________________________________________________________________________________________
1 | blbl 33 dEs '300x600' Q3 | hello 444 | RISING STARS
2 | QQQ4 Hello trueview Apple | something 68793274 | VIDEO
3 | A useless string | pre-roll Video <10 tttt 89 CASIO | VIDEO
4 | Something not in dict | Neither here | NaN
最简单的方法是什么?(如果可能的话,计算成本更低)
