Python GUI Development - Learning Path

NITIN GUPTA

 GUI stands for Graphic User Interface. As can be defined by the name, GUI is an interface with the help of which a user can interact with the device. Previously, computers didn’t support GUIs, so working with computers required many skills as every action can only be performed by using some basic commands that must be remembered. So, you must have figured out that the computer was only a working tool back then. Some of the well-known GUI examples include Microsoft Windows, macOS, and Ubuntu.

 

        

 

In today’s lecture, we will see how we can use GUI in Python and how we can learn it, and the reason we should. Every software we use consists of a front end and a back end. All the code and logic are placed in the back end, and a user interface is created in the front end. The user could easily use that without any knowledge about backend working. GUI is crucial because it is the area of human interaction with the software. In any program, ease of use should be our primary focus because most software users do not have any prior programming logic, so GUI can help a layman perform his required tasks smoothly without any prior knowledge about the software’s working.

There are a lot of options available that could help us develop a GUI for our program. Some of the well-known are:

  • Tkinter 
  • wxPython 
  • JPython

Tkinter:

We will talk about Tkinter a little bit in this tutorial. If you have seen all the tutorials of this course in series, then developing a GUI won’t be such a difficult task for you, and you will learn it in just a few tutorials. The only extra effort that you have to do is to make a habit of developing your logic. This can be done by writing your own code instead of copying it directly from the site and thinking about more than one way to solve a single problem.

Tkinter is a very important module in Python. To use Tkinter, we have to import it into our program.

import Tkinter

After that, we will create a GUI main window and use the widgets provided by the module. There are several modules that we can access using Tkinter. These include a button, scrollbar, canvas, label, menu, etc.

We also have to set the dimensions and sizes of all the widgets, and along with that, we have to specify the function or action performed by each of them is the code section. For example, we have to specify in the code section the action that will take place by clicking the button. Or what sort of text can be written in an accept bar.

So, in GUI, we have to work with the backend and frontend simultaneously. One is useless without the other. For example, if we place a button at the front end but do not specify its action on the back end, the button will be useless, as it will contain no function, hence performing no task.

For more details and descriptions and for learning GUI with Tkinter, refer to the Python GUI Tkinter Tutorials.

HOW IMPORT WORKS IN PYTHON?

NITIN GUPTA
  How does the import keyword work? When we write a certain module name along with the  import  keyword, it will start searching for a file with that name having an extension  .py . After finding the file, it will import it into our program, which means that it will permit our program to use the functions of the certain module we imported. We can import a module named  “sys”  to see the path that our import statement takes while searching for a module. import sys print ( sys . path ) Copy sys.path  prints out a list of directories. When we tell Python to import something, then it looks in each of the listed locations in order.  A common mistake that most of the beginners do and also the primary reason for making this tutorial is, why can’t we name our file, the same as the name of a module. The reason is associated with the path. When we give our file a name same as the name of a module, then instead of importing the original module, the system ...

Exercise 5: Health Management System

NITIN GUPTA
  Exercise#5 The task is to create a " Health Management System ." Suppose you are a fitness trainer and nutritionist. You have to deal with three clients, i.e., (Harry, Rohan, Hammad). For each client, you have to design their exercise and diet plan. Instructions: Create a food log file for each client Create an exercise log file for each client. Ask the user whether they want to log or retrieve client data. Write a function that takes the user input of the client's name. After the client's name is entered, it will display a message as "What you want to log- Diet or Exercise". Use function def getdate ( ) : import datetime return datetime . datetime . now ( ) Copy The purpose of this function is to give time with every record of food or exercise added in the file. Write a function to retrieve exercise or food file records for any client. You are advised to participate in solving this problem. This task helps you to become a good pr...

*args and **kwargs In Python

NITIN GUPTA
  Before discussing *args and **kwargs, we should have a basic knowledge about types of arguments. In Python programming, there are two types of arguments that can be passed in a function. positional arguments keyword arguments Positional arguments  are the one in which an order has to be followed while passing arguments. We have been dealing with them until now. We know how normal functions work with positional arguments, so now we will directly start exploring keyword arguments. But to understand them, we have to know about asterisk or more commonly known in Perl 6 and ruby as a splat operator.  Asterisk is used in python as a mathematical symbol for multiplication, but in case of arguments, it refers to unpacking. The unpacking could be for a list, tuple, or a dictionary. We will discover more about it by defining *args and **kwargs. *args: args is a short form used for arguments. It is used to unpack an argument. In the case of *args, the argument could be a list or t...
