Yep, and there you have the start of it! Now you can just add the methods you want, like maybe a doAttack function,

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
from random import randint
 
class Character_1:
    def __init__(self,char):
        self.char = char
        self.gold = 0
        self.level = 1
        self.attack = 7
 
    def doAttack(self):
        # get a damage amount ranging from half
        # the attack value, up to the attack value
        # note that 'minimum' is integer division, so it'll truncate,
        # i.e. 7 / 2 = 3  (it cuts off the decimal part)
        minimum = self.attack / 2
        maximum = self.attack
        damage = randint(minimum, maximum)
        return damage
from random import randint

class Character_1:
    def __init__(self,char):
        self.char = char
        self.gold = 0
        self.level = 1
        self.attack = 7
    
    def doAttack(self):
        # get a damage amount ranging from half
        # the attack value, up to the attack value
        # note that 'minimum' is integer division, so it'll truncate,
        # i.e. 7 / 2 = 3  (it cuts off the decimal part)
        minimum = self.attack / 2
        maximum = self.attack
        damage = randint(minimum, maximum)
        return damage

Note that minimum is integer division, so it's essentially rounding down by cutting off the decimal point. And the randint function chooses a random integer in the range from minimum up to and including the maximum.

EDIT:
In response to you wanting to add 200 gold to the player upon initialization, then just change the self.gold = 0 inside __init__ to self.gold = 200 .

Nice, that will come in handy, I will change that self.gold to 200, that way I can cut out the middle man.. I will work on this some more today and post some code up ..

Ok, so here is what I have now. I basicly tied everything into Leveling up..So in order to get and do stuff you have to level up. You might know a better way, but I thought this would work well.. pay no mind to that variable 'x' that is just a place holder. And for now the 'Attack' function is just setting there..

I see an error. Why do you have if player.Level_Up >= 1 ? Shouldn't that be if player.level >= 1 ? The value of player.Level_Up (which is the function) will be something like <bound method Character_1.Level_Up of <__main__.Character_1 object at 0x00D89110>>
And you can also simplify those additions you make by using the += operator. So instead of player.gold = player.gold + 125 you can write player.gold += 125 . Similar operators are:
-=
*=
/=

I tried changing that to .level but when I do I get an error, when I use the Level_Up I put in 0 for x and get what I asked for..I dont know.. I may have something screwie going on, I will figure it out im sure.

I will change the operators to -= and += that will make things a little cleaner..Hey at least now I am asking good questions instead of stupid ones, or just having you help me make things cleaner or neater. yay im learning lol XD

EDIT: Well maybe I do have a stupid question..How would I build a menu option that pops up before the Class Character_1 pops up? I know how to build it, but what can I do do delay the Character class from poping up? I have a thought that is is the __init__ but don't I still need that?

What I am thinking is building that class for Character_1 and haveing a class Main_Menu that pops up first and lets you choose a character that will start the next class..

Oh! How could I miss it! You're using things like player.gold and player.level , etc. That's wrong, because player is undefined within that scope. When you're changing a class' properties and such from within itself, you use self. Your Level_Up function should read:

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
def Level_Up(self, x):
        self.level += 1
        self.gold += 125
        self.attack += 2
        self.defend += 1
        if self.level >= 1:
            print 'Level:',
            print self.level
            print 'Gold:',
            print self.gold
            print 'Attack',
            print self.attack
            print 'Defend:',
            print self.defend
def Level_Up(self, x):
        self.level += 1
        self.gold += 125
        self.attack += 2
        self.defend += 1
        if self.level >= 1:
            print 'Level:',
            print self.level
            print 'Gold:',
            print self.gold
            print 'Attack',
            print self.attack
            print 'Defend:',
            print self.defend

That's what has been messing it up

did you see the rest of my question? I noticed you posted about the time I was editing my post above^.

Also now when I change everything from player to self. I get the error 'self' is not defined when I call the function Level_Up

EDIT: never mind helps to change 'player = Character_1 to 'self'
major

on me..

Now what about this question I had above?
EDIT: Well maybe I do have a stupid question..How would I build a menu option that pops up before the Class Character_1 pops up? I know how to build it, but what can I do do delay the Character class from poping up? I have a thought that is is the __init__ but don't I still need that?

Remember that the script executes downwards; it doesn't all happen at once. Things like raw_input also stall until input is given, then the script continues. So this is fairly easy to do; here's an outline of what you'll want:

 Help with Code Tags 
 Python Syntax (Toggle Plain Text) 
class MainMenu(object):
    def __init__(self):
        # do your stuff here
    def askWhichClass(self):
        choice = raw_input("Which class?  ")
        return choice
 
# define your player classes here...
 
mm = MainMenu()
choice = mm.askWhichClass()
if choice == 'serf':
    player = PlayerSerf()
elif choice == 'baron':
    player = PlayerBaron()
# etc...
class MainMenu(object):
    def __init__(self):
        # do your stuff here
    def askWhichClass(self):
        choice = raw_input("Which class?  ")
        return choice

# define your player classes here...

mm = MainMenu()
choice = mm.askWhichClass()
if choice == 'serf':
    player = PlayerSerf()
elif choice == 'baron':
    player = PlayerBaron()
# etc...

This first initializes an instance MainMenu class (as mm). Then we call its method for getting the user's choice (via the raw_input statement) and then we check it with if statements to make player an instance of the appropriate class.
Hope this clears up your confusion!

Perfect! If I was not so sure I would say you are a Python genius! Making my life alot easier I tend to second guess about stuff, even if I think it may work..

Thanks! Just note that with the above code you'd still need to take into account incorrect input, like a user entering an invalid option for the class, etc. You could fix the MainMenu's getWhichClass method to handle this accordingly:

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
class MainMenu(object):
    def __init__(self):
        # do your stuff here
    def askWhichClass(self):
        # available options in a list
        options = ['serf', 'baron']
        while True:
            choice = raw_input("Which class?  ")
            # check if the choice is in the options list
            # (convert to all lowercase first to allow for case-insensitive input)
 
            # if so, return the choice (which also breaks the while loop)
            if choice.lower() in options:
                return choice
           # if not, don't break out of the loop,
           # so that it regathers input until it gets a valid choice
           else:
                print 'Invalid choice!'
class MainMenu(object):
    def __init__(self):
        # do your stuff here
    def askWhichClass(self):
        # available options in a list
        options = ['serf', 'baron']
        while True:
            choice = raw_input("Which class?  ")
            # check if the choice is in the options list
            # (convert to all lowercase first to allow for case-insensitive input)

            # if so, return the choice (which also breaks the while loop)
            if choice.lower() in options:
                return choice
           # if not, don't break out of the loop,
           # so that it regathers input until it gets a valid choice
           else:
                print 'Invalid choice!'
