Question

我想根据Op.progressPercentage订购数据帧并对eventTimes求平均值，如下所示：

输入df：

uuid,eventTime,Op.progress,Op.progressPercentage, AnotherAttribute

Op.progressPercentage应该始终是单调的新月形和eventTime。对此，任何帮助都将非常感谢。最好的祝福，卡罗

Answer 1

sorted = df.sort_values(['eventTime', 'Op.progress'])

或者如果您想修改数据框，

df.sort_values(['eventTime', 'Op.progress'], inplace = True)

如果你想倒退

sorted = df.sort_values(['eventTime', 'Op.progress'], ascending = False)

在Pandas中订购Dataframe
