# extract phone numbers
# firstly, regular expression finds all numbers which can be a number
# then sorted(set(data)) removes duplicates
# then [x for x in arr if "-" in x] takes only numbers which contain "-"
# because most likely, phone number will have it
phones = [x for x in sorted(set(re.findall("\(?[\d]{3}\)?[\s-]?[\d]{3}[\s-]?[\d]{4}", content, re.DOTALL))) if "-" in x]

# if we have emails set and phones, we can process it
if emails and phones:
    unique = sorted(set(emails))
    unique += phones
