Python通讯簿

这两天在学习python语言，也学着写了个通讯簿，练习入门下！
功能包括以下：
1、增加一条记录
2、删除一条记录
3、修改一条记录
4、查询一条记录
5、显示整个通讯簿
6、帮助提示
7、版本显示
8、退出等
首先建立一个Person类，即Person.py文件，用来保存联系人记录：
class Person:
def __init__(self, name, email, phone):
self.name = name
self.email = email
self.phone = phone

接下来是个addressBook.py文件，用以实现上面提到的功能，这里用了存储器，将对象保存在文件中来实现数据存储。
import cPickle as p
from Person import Person
filename = 'addressBook.data'
while True:
order = raw_input('/////////////////////////////////////\nEnter your order:')
#add
if order == 'add':
addName = raw_input('Enter name:')
f = file(filename)
dic = p.load(f)
if dic.has_key(addName) == False:
dic[addName] = Person(addName, raw_input('Enter email:'), raw_input('Enter phone:'))
f = file(filename, 'w')
p.dump(dic, f)
f.close()
#delete
elif order == 'del':
delName = raw_input('Enter name who you will delete:')
f = file(filename)
dic = p.load(f)
if dic.has_key(delName):
del dic[delName]
f = file(filename, 'w')
p.dump(dic, f)
f.close()
#modify
elif order == 'mod':
modName = raw_input('Enter name who you will modify:')
f = file(filename)
dic = p.load(f)
if dic.has_key(modName):
dic[modName] = Person(modName, raw_input('Enter email:'), raw_input('Enter phone:'))
f = file(filename, 'w')
p.dump(dic, f)
f.close()
#search
elif order == 'search':
schName = raw_input('Enter name who you will search:')
f = file(filename)
dic = p.load(f)
if dic.has_key(schName):
psch = dic[schName]
print psch.name
print psch.email
