How to dynamically extract numbers befor text with regex?

I have a regex function that extracts the numbers before text. But I do it now with hard coded text.

But is it also possible to extract the numbers regardless of the text.

So I have this example string:

text = "[' \n\na)\n\n \n\nFactuur\nVerdi Import Schoolfruit\nFactuur nr. : 71201 Koopliedenweg 33\nDeb. nr. : 108636 2991 LN BARENDRECHT\nYour VAT nr. : NL851703884B01 Nederland\nFactuur datum : 10-12-21\nAantal Omschrijving Prijs Bedrag\nOrder number : 77553 Loading date : 09-12-21 Incoterm: : FOT\nYour ref. : SCHOOLFRUIT Delivery date :\nWK50\nD.C.

and I have this as search words :

fruit_words = ['Appels', 'Ananas', 'Peen Waspeen',
               'Tomaten Cherry', 'Sinaasappels',
               'Watermeloenen', 'Rettich']

and this is the regex expression:

regex =  r"(\d*(?:\.\d+)*)\s*(?:" + '|'.join(re.escape(word)
                                            for word in fruit_words) + ')'

number_found = re.findall(regex, verdi3)
print(number_found)

and the output is then like this:

['16', '360', '6', '75', '9', '688', '22', '80', '160', '320', '160', '61']

My question:
Is it also possible to have the same output but then without the fruit_words?

Or mabye without regex?

Thank you

>Solution :

One approach without regex. First, we cut the text by \n, because all the numbers we need start on a new line. Then we discard those elements that do not start with a number. Next, we cut the remaining elements by spaces and get numbers.

a = text.split('\n')
b = list(filter(lambda x: x[0].isdigit() if len(x) > 0 else False, a))
c = [x.split()[0] for x in b]
print(c)

['16', '360', '6', '75', '9', '688', '22', '80', '160', '320', '160', '61']
