源代码如下：
#!/usr/bin/env python
#Filename:addressbook.py
adbook={'alice':100,'bob':101,'chanel':102}
while True:
choice=raw_input("Please input l:list,f:find numuber,e:exit the program: ")
if choice == 'l':
print "The addressbook is %s" % adbook
elif choice == 'f':
name=raw_input("Please input you name: ")
if name in adbook:
phone=adbook[name]
print "the %s phonenum is %s" %(name,phone)
else:
print "Please input the right name"
elif choice == 'e':
break
else:
print "Please input l or f"
说明：此程序耗时一个多小时，但还是不够好，感觉逻辑有点混乱，求指教。
