行之间的时间差熊猫数据框

Question

I have a time variable in my dataframe and I am trying to come up with a new column that gives the time passed in minutes from one row to another. I was trying to use this function:

df["Time"].diff()

But I get the following error:

 TypeError: unsupported operand type(s) for -: 'datetime.time' and 'datetime.time'

Is there any way I can create a column in pandas with the time difference from one row to the next one?

您可以将Time列转换为具有默认相同date的datetimes时间，因此Series.diff运行良好：

df['difference'] = pd.to_datetime(df["Time"].astype(str)).diff()
