[FIXED] python basic class question, where am i going wrong

Issue

I'm slowly trying to get my head around classes. I have a few working examples which i kinda understand but can someone please explain to me why this doesn’t work?

class python:
  def __init__(self,name):
    self.name=name

  def changename(self,newname):
    self.name=newname

abc=python('python')

print abc.name

abc.changename = 'anaconda'

print abc.name

All I’m trying to do here is change the value of abc.name at some point later in the code (it doesn’t need to be name if that’s a special word, but I did try name2, etc, same results...)

If I do print abc.changename then I get the output anaconda but that’s not really what i wanted.

Any help would be much appreciated.

Also...Is it possible to do something like that at a later point in the life cycle of the code?

def newstuff(self, value1, value2):
  self.newvalue1 = value1
  self.newvalue2 = value2

So that I would have access to 2 new ‘things’ abc.newvalue1 and abc.newvalue2.

Does that make sense??

Sorry for the ‘things; I’m still trying to grasp which is an attribute, object, method, item, etc...

Solution

Try changing this line:

abc.changename = 'anaconda'

to this:

abc.changename('anaconda')

You defined the method changename to access your member name. Then, in the first line you try to access the member directly without using the method.

In the second case, yes it would work:

def newstuff(self, value1, value2):
    self.name1 = value1
    self.name2 = value2

But you would have to add 1 member to your class, and should then access the method like this:

class python:
    def __init__(self, value1, value2):
        self.name1 = value1
        self.name2 = value2


abc=python('python1', 'python2')
abc.newstuff('snake', 'anaconda')
