Comment In this tutorial, we will learn how to develop graphical user interfaces by writing some Python GUI examples using the Tkinter package. Tkinter package is shipped with Python as a standard package, so we don't need to install anything to use it. Tkinter is a very powerful package. Sounds Cool!! We will use Python 3. We will start by creating a window to which we will learn how to add widgets such as buttons, combo boxes, etc. Then we will play with their properties, so let's get started.

This function calls the endless loop of the window, so the window will wait for any user interaction till we close it. To add a label to our previous example, we will create a label using the label class like this:. You can set the label font so you can make it bigger and maybe bold. You can also change the font style. Let's try adding more GUI widgets like buttons and see how to handle button click events. Let's start by adding the button to the window.

The button is created and added to the window in the same way as the label:.

Note that we place the button on the second column of the window, which is 1. If you forget and place the button on the same column which is 0, it will show the button only, since the button will be on the top of the label.

Now, if you tried to click on the button, nothing happens because the click event of the button isn't written yet. Now, if you click the button, it will show the same old message, but what about showing the entered text on the Entry widget? So we can write this code to our clicked function like this:. If you click the button and there is text in the entry widget, it will show "Welcome to" concatenated with the entered text.

Every time we run the code, we need to click on the entry widget to set focus to write the text, but what about setting the focus automatically?

And when you run your code, you will notice that the entry widget has the focus so you can write your text right away. To set the selected item, you can pass the index of the desired item to the current function. Also, you can set the checked state by passing the check value to the Checkbutton like this:. Note that you should set the value for every radio button with a different value, otherwise, they won't work. Also, you can set the command of any of these radio buttons to a specific function, so if the user clicks on any one of them, it runs the function code.

To get the currently selected radio button or the radio button's value, you can pass the variable parameter to the radio buttons and later you can get its value. Every time you select a radio button, the value of the variable will be changed to the value of the selected radio button. Here we specify the width and the height of the ScrolledText widget, otherwise, it will fill the entire window. You can show a warning message or error message the same way.Popular Snake game with Python-Pygame module.

Important: If you try to run this script without special png-wav files it will fail, you have to put following files to a directory with this script. They are basically apple picture, head of snake, intro sound and dead sound. Without them script will not run. Just make inactive the statements intro. Or you can play the game just install it.

Its showing the error that there's not module named "pygame". This game is impossible to run because in lines 3,4,5 you import files that you have on your computer.

You need to put links to the data from the files in order for others to be able to use this code. Plus the images are png's that you have saved. You need to add attachments to all the external files in order for the code to be executed. Salad Burns No, lines 3,4,5 are not files in my computer. They are 3rd part modules.

The last line which calls mainloop function, this function calls the endless loop of the window, so the window will wait for any user interaction till we close it. Then we will set its position on the form using the grid function and give it the location like this:. You can set the label font so you can make it bigger and maybe bold.

You can also change the font style. Great, but the window is so small, we can even see the title, what about setting the window size? Note that we place the button on the second column of the window which is 1. If you forget and place the button on the same column which is 0, it will show the button only, since the button will be on the top of the label.

Now, if you click the button, it will show the same old message, what about showing the entered text on the Entry widget? First, you can get entry text using get function. So we can write this code to our clicked function like this:. Every time we run the code, we need to click on the entry widget to set focus to write the text, what about setting the focus automatically?

Here we specify the width and the height of the ScrolledText widget, otherwise, it will fill the entire window. You can show a warning message or error message the same way. The only thing that needs to be changed is the message function.

You can choose the appropriate message style according to your needs. Just replace the showinfo function line from the previous line and run it. If you click OK or yes or retryit will return True value, but if you choose no or cancelit will return False.

The only function that returns one of three values is askyesnocancel function, it returns True or False or None. To set the Spinbox default value, you can pass the value to the textvariable parameter like this:. You can set this value based on any process you want like downloading a file or completing a task.

First, we will create a style and set the background color and finally set the created style to the Progressbar. You can specify the file types for a file dialog using filetypes parameter, just specify the extensions in tuples.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I have just installed Ubuntu and am re-familiarizing myself with Python. I learned the basics in late early and I'm practicing with it in order to get better at programming concepts and practice. If you haven't read it already I'd highly recommend that you check out PEP8 as it is a great starting point for a lot of questions about Python code conventions. Some of what I write here will be repeated there. One issue with your design is that your functions are designed such that you must call them in a particular sequence in order to get the results you want.

While this might be somewhat appropriate in this case it is usually indicative of bad design. Generally speaking the more you can make your functions not depend on side-effects the better as it allows you more effective code reuse opportunities. Use your version control software to manage your changes in code instead of commenting out code. If you are not using version control then you should strongly consider learning how as this is one of the most valuable productivity boosters you can get with development.

If you want logging perhaps look into the standard library logging module. You have used comments fairly extensively in the code here which definitely helps when reading it. Also I noticed you put a docstring for the module which is good to see! When I'm reading this code I have to guess from the context that the is the keycode for the up key.

I have to read ahead and look at the context to figure this out. I notice a similar situation with the directions, create a variable for the various different directions instead of hardcoding strings everywhere. For example in a lot of places in the code you have lines such as:. This makes means if you change the type of value stored in self. Currently you would have to track down all the different strings and change them.

Having used other languages I think this is a very good example of where an enumeration type is useful but others might consider that somewhat un-pythonic, so do whatever you think is most readable. Going further I'd consider making some sort dictionary to store the keycode along with the associated action that needs to be done if you start getting more keyboard keys being used in your program. I'll explain this in more depth if you make a follow up question.Many people would agree if I say Python is really fun to learn and fiddle around with.

Python is a high-level, object-oriented, interpreted programming language, which has garnered worldwide attention.

The answer to this question is fairly simple and straightforward. It all starts with learning the basics and all the fundamentals of Python. This is basically a measurement index to know how comfortable you are working with Python. The next prime step involves taking a look at the basic and easy code to familiarize yourself with the syntax and the flow of logic in the code. This is a very important step and helps set a strong foundation for later on as well.

After this, you should definitely look at what python is being used for in real life. This will play a major role in finding out why you want to learn Python in the first place.

Followed by this is definitely to look at what projects you can tackle your current knowledge of Python. Diving into the depth of Python will help you assess yourself at every stage. Projects are basically used to solve a problem at hand.

If providing solutions to the various simple and complex problems are your kind of a thing, then you should definitely consider working on Python projects. The best beginner project we can consider is the game of Hangman. I am sure the majority of you reading this Python Projects blog has played Hangman at one point of time in your life.

As simple as it sounds, it has certain key things you need to note. Let us keep it simple and use a text file for the input. The text file consits of the words from which we have to guess.

Python GUI examples (Tkinter Tutorial)

You will also need functions to check if the user has actually inputted a single letter, to check if the inputted letter is in the hidden word and if it is, how many times it appearsto print letters, and a counter variable to limit guesses. Now that we saw how we can tackle a beginner project like Hangman, let us step it up a little and check out an intermediate Python Project next. The best way to get started with learning intermediate stages of programming in Python is to definitely start working with the libraries that Python supports.

Some are very easy and straightforward while some might take some time to grasp and master. Scipy uses arrays like basic data structure used for linear algebra, calculus, and other similar concepts.

Pandas are used for dataframes and Matplotlib is to visualize data in the form of graphs and notations. The best possible usage of Python is for data visualization. As helpful as numeric data output is, there are many requirements of a visual representation of the data.

By visual representation, it is just a generalization. Anything ranging from creating your front-end or a Graphical User Interface GUI to plotting numeric data as points on a graph. Matplotlib is used to plot data points on a graph. There are many options for doing 3D plots in Python, but here are some common and easy ways using Matplotlib. In general, the first step is to create a 3D axes, and then plot any of the 3D graphs that best illustrates the data for a particular need.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Lots of screenshots. If you are a professional or skilled in how to develop software, then you understand the role of documentation in the world of technology development. You can skip this bit RTFM is not a new acronym. It stretches back tothe dawn of the computer-era and in particular the microprocessor.

The point is that this is not a new problem. It's a very old problem. It WILL be required, at times, for you to read or search this document in order to be successful. Re-read that statement.

This will be a serious problem for you if you're the type of person that finds it "quicker and easier to post on StackOverflow rather than reading documentation". If you have not yet matured to the point you are able to understand this skill or choose to not follow it, then please save everyone the pain of doing for you what you, as a developer, software engineer, or wanna be coder, must do on your own.

It's a vital skill for you to learn. Want to be a "real engineer"?

Then follow "real engineering practices" such as "reading". You've not seen anything like it. Don't be so arrogant as to believe you will never need to read documentation. There are 5 resources that work together to provide to you the fastest path to success. They are:. Pace yourself. However, GUIs take time and thought to build. Take a deep breath and use the provided materials and you'll do fine. Don't skip the design phase of your GUI after you run some demos and get the hang of things.

It may feel like the 3 days you've been working on your code has been forever, but by comparison of 3 days learning Qt, PySimpleGUI will look trivial to learn. This documentation is not HUGE in length for a package this size.We have previously seen how to write text-only programs which have a command-line interfaceor CLI. Now we will briefly look at creating a program with a graphical user interfaceor GUI. In this chapter we will use tkintera module in the Python standard library which serves as an interface to Tk, a simple toolkit.

There are many other toolkits available, but they often vary across platforms. If you learn the basics of tkinteryou should see many similarities should you try to use a different toolkit.

We will see how to make a simple GUI which handles user input and output. GUIs often use a form of OO programming which we call event-driven : the program responds to eventswhich are actions that a user takes.

Anything that happens in a user interface is an event. We say that an event is fired whenever the user does something — for example, clicks on a button or types a keyboard shortcut.

Tkinter GUI Application Development HOTSHOT by Bhaskar Chaudhary

Some events could also be triggered by occurrences which are not controlled by the user — for example, a background task might complete, or a network connection might be established or lost. Our application needs to monitor, or listen for, all the events that we find interesting, and respond to them in some way if they occur. To do this, we usually associate certain functions with particular events. We call a function which performs an action in response to an event an event handler — we bind handlers to events.

We call these elements widgets. We are going to construct a tree of widgets for our GUI — each widget will have a parent widget, all the way up to the root window of our application. For example, a button or a text field needs to be inside some kind of containing window.

The widget classes provide us with a lot of default functionality. Once we have constructed the backbone of our GUI, we will need to customise it by integrating it with our internal application class.

Try executing this code for yourself. You should be able to see a window with a title, a text label and two buttons — one which prints a message in the console, and one which closes the window. The window should have all the normal properties of any other window you encounter in your window manager — you are probably able to drag it around by the titlebar, resize it by dragging the frame, and maximise, minimise or close it using buttons on the titlebar.

The window manager is the part of your operating system which handles windows. All the widgets inside a window, like buttons and other controls, may look different in every GUI toolkit, but the way that the window frames and title bars look and behave is determined by your window manager and should always stay the same.

We are using three widgets: Tk is the class which we use to create the root window — the main window of our application.
