一个小小的文本行信息管理程序

程序的功能：创建一个的命令行 地址簿 程序。在这个程序中，可以添加、删除和搜索你的联系人（朋友、家人和同事等等）以及它们的信息（诸如电子邮件地址和/或电话号码）。

代码很少，如下：

import cPickle as cp
persons = {}

class Person(object):
name = 'unknown'
sex = 'unknown'
age = '0'
relation = 'unknown'
phone = 'unknown'
email = 'unknown'
def __init__(self,name):
self.name = name
def __str__(self):
return "name:%s sex:%s age:%s phone:%s email:%s" % (self.name,self.sex,self.age,self.phone,self.email)

def load():
f = file("addrs.data",'r')
if f.readline():
# file pointer untreads
f.seek(0,0)
persons = cp.load(f)
f.close()
return True
else:
f.close()
return False

def dump():
f = file("addrs.data",'w')
cp.dump(persons,f)
f.close()

def add(name):
if load():
print 'true'
if persons.has_key(name):
s = raw_input("This person exists, do you want to override the information?y or n:")
if s=='n' or s=='N':
return

p = Person(name)
p.sex = raw_input("sex:")
p.age = raw_input('age:')
p.relation = raw_input('relation:')
p.phone = raw_input('phone:')
p.email = raw_input('email:')

persons[name] = p
dump()

def delete(name):
if not load():
print 'no data'
return

#delete the person
if persons.has_key(name):
del persons[name]
print "%s has been deleted" % name
else:
print "no such person"
dump()

def search(name):
if not load():
print 'no data'
return

if persons.has_key(name):
print persons[name]
else:
print 'no such person'

程序很小，不过是我写的第一个完整的python程序，写下来纪念一下
