A simple example of a Python program (newsletter) _python

Core code:

Copy Code code as follows:

#!/usr/bin/python
#Filename: friendbook.py
Import Cpickle as P
Import Sys
Import time
Import OS

ab={' xdex ': ' cneds@fnedf.com ',
' laexly ': ' fev@fe.com ',
' FUKC ': ' fexok@ver.com ',
' Stifu ': ' stif@qq.com '
}

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 ' 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 '

Class Alterperson:
        def __init__ (self,name,email):
                 Self.name=name
                 Self.email=email
         def alterbook (self):
                 ab=frilist
                 Ab[sname]=email
                 dumpfile (AB)
                 del AB
                 print ' succlessful update! '

print ' ' \
This is prints files to the standard output.
Any number of the files can be specified.
