最佳答案
我有一个这样的数据帧:
print(df)
0 1 2
0 354.7 April 4.0
1 55.4 August 8.0
2 176.5 December 12.0
3 95.5 February 2.0
4 85.6 January 1.0
5 152 July 7.0
6 238.7 June 6.0
7 104.8 March 3.0
8 283.5 May 5.0
9 278.8 November 11.0
10 249.6 October 10.0
11 212.7 September 9.0
如您所见,月份不是按日历顺序排列的。因此,我创建了第二列来获取每个月对应的月份号(1-12)。在此基础上,如何根据日历月份的顺序对数据帧进行排序?
