This is a simple music player program that uses Python's tkinter library and pygame library. The main features of the program include:
- Add Music Folder
- play music
- Pause/resume playback
- stop playing
- next song
- previous song
- volume control
Ideas for implementation
The program first imports the required libraries and then creates a tkinter window, setting the window title, size and non-stretchability.
Next, several global variables are defined, such as folder path, music list, index of the currently playing music, and so on. Then several functions are defined, such as buttonChooseClick, play, buttonPlayClick, buttonStopClick, buttonNextClick, buttonPrevClick, control_voice, and so on.
The buttonChooseClick function is used to select the music folder to be played and display the music list. play function is used to play the music, which is implemented using the pygame library. buttonPlayClick function is used to start playing the music, buttonStopClick function is used to stop playing the music. buttonNextClick function is used to play the next music, buttonPrevClick function is used to play the previous music. control_voice function is used to control the volume.
Finally, several button click events are defined, and the state of the buttons (e.g. disabled and enabled) is set, as well as the window close event.
In (), the program starts running, displays a window, and waits for user action.
Implementation Code
The first step is to download some music locally
Then you can attach the source code:
