I'm having some issues and just want to know what it may be because I've tested properly some of my code. Why is this code not working ? This is the code displayed below.

search_for_term = re.findall(r'<td class="kx o_\d.*data-bookmaker', doc)

This is the output of searc_for_term variable:

['<td class="kx o_1 winner" data-bookmaker',
 '<td class="kx o_0" data-bookmaker',
 '<td class="kx o_2" data-bookmaker']

Now I'm trying to find if any string contains word "winner". Code is shown below.

winner_ids = np.where([re.findall('winner', item) for item in search_for_term])

And now is the code which confuses me :

if(not all(winner_ids)):
   print("no winner")
else:
   print("winner does exist")

The output I get is "no winner". Can somebody explain this to me. I would be more than greatful.

    What exactly do you not understand? Why did you expect to get something else as output? – mkrieger1 Nov 26 '19 at 00:05
  • Will `'*winner*'` do what you want? – Han Wang Nov 26 '19 at 00:08
  • Well, should it display winner does exist because winner is located in winner_ids judging by the array ? – newnick988888 Nov 26 '19 at 00:16
  • Use `re.search()` – CAustin Nov 26 '19 at 00:17
  • What if you print `winner_ids` to find out if your assumption is correct? – mkrieger1 Nov 26 '19 at 00:19
  • Please include all relevant code and data. See: [mcve]. It would be particularly useful here since some of these design choices seem odd. Also, it looks like you're using RegEx to parse HTML. I'm guessing you haven't seen [this legendary answer](https://stackoverflow.com/a/1732454/11301900) yet. – AMC Nov 26 '19 at 00:23

Don't do this: RegEx match open tags except XHTML self-contained tags

Use the beautiful soup.

Then you can simply use:

winner = doc.find('td.winner[data-bookmaker]')

And the condition becomes:

if winner:
    print("winner exists")
else:
    print("no winner")

Reply to comment: You extract a copy of the DOM and feed to this.

You already are extracting the DOM as HTML and parsing it via RE. You might as well simply feed it to bs4.

i think you need 

winner_ids = np.where([re.findall('.*winner.*', item) for item in search_for_term])
