How pandas by index, it is concluded that the current index A value less than zero, and the next index greater than 0 index, such as the above index 2, accord with the requirement of me
CodePudding user response:
The import pandas as pd
Df=pd DataFrame ({' A ': [1, 2, or 3,1,2,3,4,5, 1, 1, 2,1,2,3,4,4]})
Dc1=df [' A '] <0
Dc2=df [r]. 'A' shift (periods=1, fill_value=https://bbs.csdn.net/topics/0)> 0
Print (df [dc1 & amp; dc2])
If no ready-made functions, my general ideas
