In this course, you will get a comprehensive overview of Python. You will start by laying the foundation and learning the introductory topics like operators, conditional statements, functions, loops, assignment statements, and more. You will then move onto more advanced topics such as classes and inheritance, iterators, list comprehensions, and dictionaries. Along with this, you will also get to explore the concept of testing and take a look at how GUI applications can be designed using Tkinter, Python's standard GUI library. 

By the time you're done, you'll be able to hit the ground running and be equipped with the tools that will allow you to be productive in Python.

Python 3: From Beginner to Advanced

## Overview of a GUI program

The window that opens when you run a GUI program is a **container**, meaning the section that contains the widgets (buttons, text areas, etc.). A **frame** is a container that you can put inside a window, or in another frame.

## Methods for arranging widgets

There are three methods for arranging widgets into the main window and frames: 
1. `pack`
2. `grid`
3. `place`

Only one of these methods should be used in any given window or frame.

Complex layouts can also be created by putting multiple frames into the window and/or into other frames and using different layouts for the window and each frame.

### Pack frame

The `widget.pack(options)` just **adds** the widget to the **window or frame**. Here, the `options` are the following:

* Use `side=side`  where `side` is one of `LEFT`, `RIGHT`, `TOP`, or `BOTTOM` to add widgets starting from that side.

* Use `expand=True`  to expand the widget to fill available space.
* Use `fill=how`  to expand the widget, where `how` can be `X` (horizontally), `Y` (vertically), `BOTH`, or `NONE`.

The following is an example of this:
