核心代码：
代码如下:
#!/usr/bin/python#filename:friendbook.pyimport cpickle as pimport sysimport timeimport os

def dumpfile(list): f=file(friendab,’w’) p.dump(list,f) f.close()
if os.path.isfile(‘friendab.data’): friendab=’friendab.data’else: os.touch(‘friendab.data’) dumpfile(ab) del ab
f=file(friendab)frilist=p.load(f)
class person: def __init__(self,name): self.name=name def saysome(self): print ‘the friend %s,his e-mail is %s ‘%(sname,frilist[sname])class addperson: def __init__(self,name,email): self.name=name self.email=email def addbook(self): ab=frilist ab[sname]=email dumpfile(ab) del ab print ‘succlessful!’class delperson: def __init__(self,name): self.name=name def delbook(self): ab=frilist ab.pop(sname) dumpfile(ab) del ab print ‘success del’

print ”’\this program prints files to the standard output.any number of files can be specified.options include:[1] : search your friend’s email from friendsbook[2] : add your friend’s email to firendsbook[3] : del your friend’s email from firnedsbook[4] : alter your friend’s email from friendsbook[5] : all friends list[6] : exit the program”’
num=raw_input(‘press the number [1,2,3,4,5] –>’)

注：这是本人写的第一个python，有诸多不足，以后改进
