我在 python 中有这个 Pandas Dataframe,我想知道两行之间的时间差,下一行减去前一行,我应该如何处理?

Reviewed[x] - Reviewed[x-1] x 是该行所在的编号

   ReporterID        ID      Type                   Reviewed
0     27545252  51884791  ReportID 2015-01-14 00:00:42.640000

5     29044639  51884797  ReportID 2015-01-14 00:01:17.400000
6     29044639  51884798  ReportID 2015-01-14 00:01:57.600000

最佳答案

假设您的 Reviewed 列是您可以执行的日期时间:

df.ix[4, 'Reviewed'] - df.ix[3, 'Reviewed']

如果您想一次对所有行执行此操作:
df['Reviewed'] - df['Reviewed'].shift()

关于python - 减去下一行使用当前行,python 数据帧,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/28120122/
