这段代码模拟合并2本联系簿。为什么我的程序错误(python)?
我的第18行代码错误没有明显的原因与短语错误。我很确定这个措辞是正确的,程序应该运行,但每次我得到一个短语错误。
class ContactBook:
"""
This class represents a book of contacts.
It can store names and phone numbers.
"""
def __init__(self):
# Create an empty dictionary
self.contacts = {}
def __repr__(self):
# Just print a string version of the dictionary
return str(self.contacts)
def __add__(self, other):
con2 = ContactBook()
for name in self.contacts:
if name in other.contacts and self.contacts[name] != other.contacts[name]:
con2.contacts[name] = self.contacts[name] + " or " + other.contacts[name]
else:
con2.contacts[name] = self.contacts[name]
for name in other.contacts:
if name not in self.contacts:
con2.contacts[name] = other.contacts[names]
return con2
def add_contact(self, name, number):
# Adds a name --> phone number pair to
