Python. When to pass parameters to a class?

Question

Python

I'm learning Python in conjunction with Kivy.
Got a question. Although, I understand that it is more general and has little to do with kiwi.
Is there a difference when to specify the parameters of the created class instances: when creating an instance or later, through properties. Perhaps I'm still confused in terminology, it will be clearer in the code. For example, I create a button with parameters in two ways - both seem to work.
Is there a fundamental difference? The second way seems more attractive because of the IDE hints, although it takes more lines.

button = Button(text='Hello world', font_size=14, background_color=[.5, 0, 0,0])
layout.add_widget(button )

button = Button()
button.text='Hello world'
button.font_size=14
button.background_color=[.5, 0, 0,0]
layout.add_widget(button )

Answer 1

in the first option, you initialize with already given values, and in the second, you initialize with an empty one, and then you replace the empty values ​​​​with the desired ones
