python basic class question, where am i going wrong

design a class that store the information of student and display the same in python
python classes and objects exercises
what is "self" typically used for in a python method within a class?
in python a function within a class definition is called a
what is instantiation in terms of oop terminology?
in object oriented programming, what is another name for the "attributes" of an object?
which of the following is rarely used in object oriented programming?
which of the following is required to create a new instance of the class?

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):

  def changename(self,newname):



abc.changename = 'anaconda'


All I’m trying to do here is change the value of 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...

Try changing this line:

abc.changename = 'anaconda'

to this:


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')

Online Python quiz, Once you have the class defined, it is easy to instantiate it anytime. You can use a class object to reference any of its attributes. Let's see a simple example to� Python Exercises, Practice, Solution: Practice with solution of exercises on Python Class : As the Python is called an object-oriented programming language a construct in Python called a class that lets you structure your software in a particular way. Using classes, you can add consistency to your programs so that they can be used in a cleaner way.

abc.changename is a method. To use it, write it with the parenthesis and the value into them. abc.changename('anaconda') Hope it'll help you

15. Classes and Objects — the Basics — How to Think Like a , Python is an object-oriented programming language, which means that it provides The question, then, is how to group these two values into a compound object. Every class should have a method with the special name __init__. If we are really fussy, we would argue that the __init__ method's docstring is inaccurate. Im just try to build a basic class so that I can learn some more about python. So far I have the following : class Bodymassindex: count = 0 def __init__(self,name,weight,height): =

You declared abc.changename as a function. Invoke it by using abc.changename("Sandman112")

What you did is you assigned a string to the member variable abc.changename instead of the class method you defined eariler.

It’s easy to define a class in Python using the <class> keyword. Check out a simple class definition below. class TestClass: ''' It is a doc string. I've implemented a new class. ''' pass. In the above code, you can see the highlighted doc string specifying the description of the class.

  • Does this answer your question? Python changing variable values declared in __init__
  • abc.changename is a method. Why are you assigning a string to it: abc.changename = 'anaconda'? Also, while you're just starting learning Python, switch to Python 3.x as Python 2 will stop receiving updates in 2020
  • Change abc.changename = 'anaconda' to abc.changename('anaconda'). changename is a function, not a variable, and has to be treated accordingly. :)
