python - Using a constantly changing variable to define a list -

i want make piece of code pulls title , link off rss feed , compiles variable can used in message body. problem body gets redefined every time pull info off rss. new programming , python, , under impression using list best thing do.

for in range(3):      messagetitle = feed['items'][i].title     messagelink = " - ",feed['items'][i]['link']      body = "%s%s%s%s" % (messagetitle,"\n","\n", messagelink) #in unicode      gmail_user = "user@gmail.com"     gmail_pwd = "pw"      mail("user@gmail.com",          "reddit update",          body) 

i going insert list below body, , use body define it.. like:

list[i] = [body] 

am on right track?

there variety of design patterns can consider using. demonstrate few don't need use [i] even:

accumulator:

messages = [] feeditem in feed['items']:     message = {'title':..., ...}     message['link'] = ...  # alternative     messages += [message]   # or messages.append(data)  print(messages) 

mapping (often elegant solution in simple cases this):

def makemessage(feeditem):     message = {'title':..., ...}     return message  messages = [makemessage(fi) fi in feed['items']] print(messages) 

generators:

def makemessages(feeditems):     item in feeditems:         message = {'title':..., ...}         yield message  messages = list( makemessages(feed['items']) ) 

---

unrelated addendum: might consider making class messages:

class message(object):     def __init__(self, title, link, body):         self.title = title         self.link = link         self.body = body      def __str__(self):         return ...     def __repr__(self):         return self.__str__()
