I'm a beginner in OOP programming and I'm wondering what is the best way to put all the windows and functions of a window application in the code.
My biggest questions are:
- Am I using classes and function in the right way?
- There is an efficient way to create windows and widgets?
- Why do I see so many peoples inheriting from
tk.Framein window classes? - In the example of application given in Tkinter documentation, they put the widgets inside a method called "create_widgets", is this recommended instead put them in the
__init__method?
I translated the interface from the original Brazilian Portuguese before posting the question here.
"""Componentes Curriculares V0.1.

I'm a beginner in OOP programming and I'm wondering what is the best way to put all the windows and functions of a window application in the code.
My biggest questions are:
- Am I using classes and function in the right way?
- There is an efficient way to create windows and widgets?
- Why do I see so many peoples inheriting from
tk.Framein window classes? - In the example of application given in Tkinter documentation, they put the widgets inside a method called "create_widgets", is this recommended instead put them in the
__init__method?
I translated the interface from the original Brazilian Portuguese before posting the question here.
"""Componentes Curriculares V0.1.
This program is meant to be a task manager to your School Year.
It is composed by various functions such as:
-List of all your tasks and tests, and a complete school report based on these
tasks. (This last one still is a work in progress.)
You can also add your topics for each subject that you are having along the
year.
The main language of the interface is Portuguese and their source code was
written in English.
Python 3.7 is the current version.

I'm a beginner in OOP programming and I'm wondering what is the best way to put all the windows and functions of a window application in the code.
My biggest questions are:
- Am I using classes and function in the right way?
- There is an efficient way to create windows and widgets?
- Why do I see so many peoples inheriting from
tk.Framein window classes? - In the example of application given in Tkinter documentation, they put the widgets inside a method called "create_widgets", is this recommended instead put them in the
__init__method?
I translated the interface from the original Brazilian Portuguese before posting the question here.
"""Componentes Curriculares V0.1.
This program is meant to be a task manager to your School Year.
It is composed by various functions such as:
-List of all your tasks and tests, and a complete school report based on these
tasks. (This last one still is a work in progress.)
You can also add your topics for each subject that you are having along the
year.
The main language of the interface is Portuguese and their source code was
written in English.
Python 3.7 is the current version.
