Python 我想在excel工作表中合并重复项

我有4个字段，主要电话（p1）、次要电话（p2）、主要电子邮件（e1）、次要电子邮件（e2）。 如果p2字段为空，则新行的p1值应转到p2

我可以合并p编号字段，但无法合并p电子邮件和se电子邮件 请查找以下代码：

def merge_or_delete_contact(self, contact, contact_list):
        query_params = self.query_params(contact)
        if len(query_params):
            old_contact = contact_list.contacts.filter(query_params).exclude(id=contact.id).first()
            if old_contact:
                old_contact.secondary_phone_number = contact.primary_phone_number
                old_contact.secondary_email = contact.primary_email
                old_contact.name = contact.name if contact.name else old_contact.name
                contact.delete()
                old_contact.save()
                return old_contact
        return contact

def query_params(self, obj):
    query = Q(secondary_phone_number=obj.primary_phone_number)
    if obj.secondary_phone_number:
        query = query | Q(primary_phone_number=obj.secondary_phone_number)
    if obj.primary_email:
        query = query | Q(primary_email=obj.primary_email)
    if obj.secondary_email:
        query = query | Q(secondary_email=obj.secondary_email)
    return query
