Hi there I have the Following Code, which I run in Jupyter Notebook :-

soup = BeautifulSoup(res.content,'lxml')
table = soup.find_all('table', align="CENTER")[0]
df = pd.read_html(str(table))
df = df[0]

And when I include that last line of Code, it correctly outputs the earliest days in the DataFrame Output first, i.e. 10 before 15, but not in the month order I want :-
LOCATION DATE DAKOTA HURRICANE SPITFIRE
MyIdx
176 Duxford 10-Jul-2004 D H S
177 Cirencester 10-Jul-2004 D H S
178 Brize Norton 10-Jul-2004 D H S
74 Shrivenham 20:00 10-Jun-2004 D H S
257 Campbletown 15-Aug-2004 D -- S
258 Sunderland 15-Aug-2004 D -- S
261 Scampton 15-Aug-2004 D -- S
200 RIAT Fairford 15-Jul-2004 D -- SS
22 Tilford 15-May-2004 D -- S
23 Abingdon 15-May-2004 D -- S
24 Hyde Heath Village 15-May-2004 D -- S
I want 10th June 2004 first then the 10th of July/s then the 15th of May's then the 15th of July Rows, then the 15th August Rows. How do I modify that line of Code, so that I can filter to get that order, without changing the index position of the Rows via code, which I know how to do ?
I mean add something to the first line of code e.g. the displays.sort_values Line, so that the Earlier month with a day, is shown 'favoured' before the later month with the same day ? i.e. 10-Jun-2004 is shown before 10-Jul-2004 , 15-May-2004 is shown before 15-Jul-2004 Rows etc. But still dates with day 10, showing before day 15 Rows.
(df3['DATE'].str.contains('-10$|15$'))
Was the part of the Code, I use to filter the days of the month, I want included
in the DataFrame Output.
Any help would be much appreciated.
