I/O reading from a file (python)

Ok, I have an IRC bot and I have a file full of nicknames (which are the admins for the bot), for example if someone types "!op" in the channel how would I go about making the bot read the file to see if the user who typed "!op" is in the list of admins and if he is then proc开发者_如何学JAVAeed with the action.. I'm just confused on how to make it read the file for the authorized users.. Your help will be appreciate it. Thanks.

Can I use something like this..

      def isadmin(nick, 'masters.txt'):
      for admin in file:
          if nick == admin.rstrip():
              return True
      return False

     if data.find('!op') != -1:
     nick = data.split('!')[ 0 ].replace(':','')
     if nick == isadmin(nick, open('masters.txt')):
        sck.send('MODE ' + chan + ' +o ' + nick + '\r\n')
     else:
          sck.send('PRIVMSG ' + chan + ' :' + ' youre not my master ' + '\r\n')

You should probably just run through the whole Python tutorial. There is a whole section about reading and writing files.

I assume your names are line seperated.

def isadmin(name, file):
    for admin in file:
        if name == admin.rstrip():
            return True
    return False

But they could also be comma seperated.

def isadmin(name, file):
    for admins in file:
        if name in admins.rstrip().split(","):
            return True
    return False

And use it like this:

isadmin("bob", open("admins.txt"))

admins = set(nick.strip() for nick in open('masters.txt'))

def isadmin(nick):
    return nick.strip() in admins

File reading is expensive enough that you don't want to re-read the file too often; if it's short, read it once and keep it in memory.
