我有一个熊猫数据框,如下所示:
0 1 2 3 4 5 6 7 8 9 ...
0 USAF WBAN YR--MODAHRMN DIR SPD GUS CLG SKC L M ...
1 NaN NaN GMT NaN MPH MPH NaN NaN NaN NaN ...
2 444540 99999 201801010000 *** 0 *** 722 SCT * * ...
3 444540 99999 201801010050 *** 0 *** 30 *** * * ...
4 444540 99999 201801010150 990 2 *** 100 *** * * ...
5 444540 99999 201801010250 *** 0 *** 100 *** * * ...
我想合并前两行,删除NaN值,并使其成为列标题,如下所示:
USAF WBAN YR--MODAHRMN DIR SPD GUS CLG SKC L M ...
GMT MPH MPH ...
0 444540 99999 201801010000 *** 0 *** 722 SCT * * ...
1 444540 99999 201801010050 *** 0 *** 30 *** * * ...
有没有办法我可以正确地做到这一点?
