A standard order is called the ascending order: a to z, 0 to 9. The reverse order is called the descending order: z to a, 9 to 0. For dates and times, ascending means that earlier values precede later ones e.g. 1/1/2020 will sort ahead of 1/1/2021. Stable sort Astable sortis...
的另一个参数.sort_values()是ascending。默认情况下.sort_values()已经ascending设置True。如果您希望 DataFrame 按降序排序,则可以传递False给此参数: >>> >>> df.sort_values( ... by="city08", ... ascending=False ... ) city08 cylinders fuelType ... mpgData trany year 9 23 4 Regular .....

bool = FalseSort the list in ascending order and return None.The sort is in-place (i.e. the list itself is modified) and stable (i.e. theorder of two equal elements is maintained).If a key function is given, apply it once to each list item and sort them,ascending or descending, ...
