appels_royal_gala = 'Appels Royal Gala 13kg 60/65 Generica PL Klasse I'

def make_pattern(substr):
    return r"(?<=" + substr + r").*?(?P<number>[0-9,.]*)n"

allSubstring = re.findall(make_pattern(appels_royal_gala), text)
print(allSubstring[0])

# Prints
3.304,08

If you care about the index, you can still use re.search and then you should do print(allSubstring[1]) (instead of 0).

This solution assumes the number you’re looking for is allways followed by n, which seems to be a constant in your example.
