Today, I will talk to you about how to use Python for graphical user interface and game development, many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

GUI based on tkinter module

GUI is an acronym for graphical user interface. The graphical user interface should be familiar to people who have used computers, and there is no need to repeat it here. Python's default GUI development module is tkinter (called Tkinter in previous versions of Python3), which is based on Tk. Tk is a toolkit originally designed for Tcl and later ported to many other scripting languages to provide cross-platform GUI controls. Of course, Tk is not the latest and best choice, and there is no particularly powerful GUI control. In fact, developing GUI applications is not what Python is good at. If you really need to use Python to develop GUI applications, wxPython, PyQt, PyGTK and other modules are good choices.

Basically, using tkinter to develop GUI applications requires the following five steps:

Import what we need in the tkinter module.

Create a top-level window object and use it to host the entire GUI application.

Add a GUI component to the top-level window object.

The functions of these GUI components are organized by code.

Enter the main event loop (mainloop).

It should be noted that GUI applications are usually event-driven, and the reason why we want to enter the main event loop is to monitor the occurrence of mouse, keyboard and other events and execute the corresponding code to deal with the events, because the events will continue to occur, so we need such a loop to wait for the next event to occur. On the other hand, Tk provides three layout managers for the placement of controls, through which controls can be positioned. These three layout managers are: Placer (the developer provides the size and placement of the control), Packer (automatically populates the control to the appropriate location) and Grid (placing the control based on grid coordinates), which is not discussed here.

Using Pygame for game development

Pygame is an open source Python module dedicated to the development of multimedia applications such as video games, including support for images, sounds, videos, events, collisions, and so on. Pygame is based on SDL. SDL is a cross-platform multimedia development library implemented in C language and is widely used in the development of games, simulators, players and so on. On the other hand, Pygame makes game developers no longer bound by the underlying language and can pay more attention to the function and logic of the game.

Let's complete a simple Mini Game, the name of the game is "big balls eat small balls", of course, completing this game is not the key point, learning to use Pygame is not the key point, the most important thing is that we should understand how to use the object-oriented programming described above, and learn to use this programming idea to solve real problems.

Draw in the window

You can draw on the window through the function of the draw module in pygame. The graphics you can draw include: lines, rectangles, polygons, circles, ellipses, arcs and so on. It should be noted that the screen coordinate system sets the upper-left corner of the screen to the coordinate origin (0P0), the positive direction of the x-axis to the right and the positive direction of the y-axis downwards. When indicating the position or setting the size, our default units are pixels. The so-called pixel is a point on the screen, you can use the image browsing software to try to magnify a picture several times to see these points. Pygame that colors are represented by the trichromatic representation, that is, through a tuple or list to specify the RGB value of the color, each value is between 0,255, because each primary color is represented by an 8-bit (bit) value, the three colors are equivalent to a total of 24-bit composition, which is often said "24-bit color representation".

After reading the above, do you have any further understanding of how to use Python for graphical user interface and game development? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
