create a class with a constructor in python

To create a class with a constructor in python, you need to define the __init__() method. This method gets called automatically when you create an instance of the class. You should use self to refer to the instance that is being created. Here's an example:

main.py
class MyClass:
    def __init__(self, arg1, arg2):
        self.arg1 = arg1
        self.arg2 = arg2
101 chars
5 lines

In this example, MyClass has a constructor with two arguments, arg1 and arg2. These arguments get saved to the instance self using the dot notation. You can create an instance of this class like so:

main.py
my_object = MyClass("hello", "world")
38 chars
2 lines

This creates an object of type MyClass, and arg1 is set to "hello" while arg2 is set to "world". You can now access these values like this:

main.py
print(my_object.arg1) # outputs "hello"
print(my_object.arg2) # outputs "world"
80 chars
3 lines

Remember that the __init__() method is optional, but it's a good way to set up the initial state of your objects. Classes in python should always inherited from the object class.
