I am new to OOP. My idea was to implement the following class:
class name(object, name): def __init__(self, name): print name Then the idea was to create two instances of that class:
person1 = name("jean") person2 = name("dean") I know, that is not possible, but how can I pass an input-argument into an instance of a class?

By using the “self” we can access the attributes and methods of the class in python. It binds the attributes with the given arguments.
Methods are passed as arguments just like a variable. In this example, we define a class and its objects. We create an object to call the class methods. Now, to call a passed method or function, you just use the name it's bound to in the same way you would use the method's (or function's) regular name.
It is to be noted that while using class in Python, the __init__() method is mandatory to be called for declaring the class data members, without which we cannot declare the instance variable (data members) for the object of the class.
A class parameter defines a special constant value available to all objects of a given class. When you create a class definition (or at any point before compilation), you can set the values for its class parameters.
The problem in your initial definition of the class is that you've written:
class name(object, name): This means that the class inherits the base class called "object", and the base class called "name". However, there is no base class called "name", so it fails. Instead, all you need to do is have the variable in the special init method, which will mean that the class takes it as a variable.
class name(object): def __init__(self, name): print name If you wanted to use the variable in other methods that you define within the class, you can assign name to self.name, and use that in any other method in the class without needing to pass it to the method.
For example:
class name(object): def __init__(self, name): self.name = name def PrintName(self): print self.name a = name('bob') a.PrintName() bob If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
