No Output In Pandas DataFrame Query

[eddywinch82]

Hi there,

I have the following Python Code, which I run in Jupyter Notebook :-

import pandas as pd
import requests
from bs4 import BeautifulSoup
   
res1 = requests.get("http://web.archive.org/web/20020602133812/http://www.raf.mod.uk/bbmf/calendar.html")     
res2 = requests.get("http://web.archive.org/web/20020803081304/http://www.raf.mod.uk/bbmf/calendar.html")
soup1 = BeautifulSoup(res1.content,'lxml')
soup2 = BeautifulSoup(res2.content,'lxml')
table1 = soup1.find_all('table', align="CENTER")[0]
table2 = soup2.find_all('table', align="CENTER")[0]
df1 = pd.read_html(str(table1))
df2 = pd.read_html(str(table2))


   
df1 = df1[0]
df2 = df2[0]
df = pd.concat([df2, df1], axis=0)

#Months = May Jun Jul Aug Sep

#print(display)

display['DATE']= pd.to_datetime(display['DATE']).dt.strftime('%m-%d-%Y')
display=display.sort_values(by=['DATE'])
##added two lines above to convert date format
display['DATE']= pd.to_datetime(display['DATE']).dt.strftime('%d-%b-%Y')

#display.drop('LANCASTER', axis=1, inplace=True)

display=display.fillna('--')
display.to_csv(r'C:\Users\Edward\Desktop\BBMF Schedules And Master Forum Thread Texts\BBMF-2002-Code (Dakota With Fighters).csv')
display

#display[display['DATE'].str.contains('Jun')]

#print(display)

However when I run the Code, I don't get the desired Output, i.e. only the Columns are shown.

When I run the Code, using the Line above the display = line of Code I am using, i.e :-

display = df3[(df3['LOCATION'].str.contains('[a-zA-Z]')) & (df3['DAKOTA'].str.contains('D')) & (df3['SPITFIRE'].str.contains('S', na=True)) & (df3['LANCASTER'] != 'L')]

Then run the following Code, in the next Cell i.e. :-

display[display['DATE'].str.contains('Jun')]

I get the correct Output.

What do I need to change in the following Line of Code :-

display = df3[(df3['LOCATION'].str.contains('[a-zA-Z]')) & (df3['DATE'].str.contains('Jun')) & (df3['DAKOTA'].str.contains('D')) & (df3['SPITFIRE'].str.contains('S', na=True)) & (df3['LANCASTER'] != 'L')

So that I do get the correct Output, running that line of Code, instead of the first one ?

i.e. with this bit of that line of Code ? :-

(df3['DATE'].str.contains('Jun'))

Any help and info, anyone could give me, would be much appreciated.

Best Regards
