在下面的代码中,我需要打印联系人列表对象。我该怎么办?
# Test.py
class ContactList(list):
def search(self, name):
'''Return all contacts that contain the search value
in their name.'''
matching_contacts = []
for contact in self:
if name in contact.name:
matching_contacts.append(contact)
return matching_contacts
class Contact:
all_contacts = ContactList()
def __init__(self, name, email):
self.name = name
self.email = email
self.all_contacts.append(self)
我创建了2个Contact对象,但想要查看all_contacts列表中的所有元素..
答案 0 :(得分:1)
怎么样:
print(Contact.all_contacts)
或:
for c in Contact.all_contacts:
print("Look, a contact:", c)
要控制联系人的打印方式,您需要在Contact类中定义__str__
或__repr__
方法:
def __repr__(self):
return "<Contact: %r %r>" % (self.name, self.email)
或者,您想要代表联系人。
