我的代码

import vobject

with open('test.vcf') as source_file:
    vcf_read_components = vobject.readComponents(source_file)
    for item in vcf_read_components:
        print(item)

出现解析错误

为了解决这个问题，通常启用quoted-printable数据处理就足够了：

vobject.readComponents(source_file, allowQP=True)

我考虑了这些建议（再次感谢大家！）并添加了一些。这是带注释的代码：

import vobject
import datetime

with open('test.vcf') as source_file:
    contacts = vobject.readComponents(source_file, allowQP=True)
    for contact in contacts:
        # Имя, отчество и фамилия
        print(contact.fn.value)

        # Если у контакта указан день рождения выводим его в российском формате даты (DD.MM.YYYY)
        # Через разницу текущая дата и день рождения определяем сколько лет
        # Обрабатываем исключение если данного поля нет
        try:
            birthday = datetime.date.fromisoformat(contact.bday.value)
            today = datetime.date.today()
            years = (today - birthday).days // 365
            print(f'{birthday.strftime("%d.%m.%Y")} ({years} лет)')
        except AttributeError:
            pass

        # Номеров телефонов может быть несколько выводим их все
        for phone_number in contact.tel_list:
            print(phone_number.value)

        # На основе типа определяем просто его вывести (если строка) или нужно склеивать из строк (список)
        # Обрабатываем исключение если его нет
        try:
            for address in contact.adr_list:
                street = address.value.street
                if isinstance(street, str):
                    print(street)
                else:
                    print(''.join(street))
        except AttributeError:
            pass

        print()

结果：
