python文本持久化
今天很懒，就什么都不写啦！过几天不知道我还能不能看懂下面的这些？import cPickle as cp
import sys
class Person:
def __init__(self,name,tel):
self.name = name
self.tel = tel
def say(self):
print 'name:%s \t tel:%s' % (self.name,self.tel)
myfriendfile = 'myfriend.data'
def init():
m = {}
f = file(myfriendfile,'w')
cp.dump(m,f,-1)
f.close()
init()
f = file(myfriendfile)
m = cp.load(f)
f.close()
print 'please check mode:\n(a) append \t(d) delete\n(s) save\t(q) quit\n(show) show\n'
while(True):
check = raw_input('please check mode:')
if check == 'q':
break
if check == 'a':
m= Person(raw_input('please input name:'),raw_input('please input tel:'))
print '(A) currtent length:',len(m)
if check == 'd':
del m
print '(D) currtent length:',len(m)
if check == 's':
print '(S) currtent length:',len(m)
f = file(myfriendfile,'w')
cp.dump(m,f,-1)
f.close()
if check == 'se':
m.say()
print "I'm looking for you..."
if check == 'show':
f = file(myfriendfile)
m = cp.load(f)
print '------------------ show ------------------'
for key,value in m.items():
value.say()
print '------------------ over ------------------'
f.close()
