我想在熊猫中这样做:
我有2个数据帧,A和B,我想只用B值替换A的NaN.
A
2014-04-17 12:59:00 146.06250 146.0625 145.93750 145.93750
2014-04-17 13:00:00 145.90625 145.9375 145.87500 145.90625
2014-04-17 13:01:00 145.90625 NaN 145.90625 NaN
2014-04-17 13:02:00 NaN NaN 145.93750 145.96875
B
2014-04-17 12:59:00 146 2/32 146 2/32 145 30/32 145 30/32
2014-04-17 13:00:00 145 29/32 145 30/32 145 28/32 145 29/32
2014-04-17 13:01:00 145 29/32 146 145 29/32 147
2014-04-17 13:02:00 146 146 145 30/32 145 31/32
Result:
2014-04-17 12:59:00 146.06250 146.0625 145.93750 145.93750
2014-04-17 13:00:00 145.90625 145.9375 145.87500 145.90625
2014-04-17 13:01:00 145.90625 …
