This article mainly explains "how to implement a music player based on Python". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to implement a music player based on Python".

I. Environmental settings

The first step is to introduce the necessary packages

Import osimport tkinterimport tkinter.filedialogimport randomimport timeimport threadingimport pygame

In particular, pygame needs to be installed manually

Pip install pygame II. Playback function

First select the music catalog, and then create a ready-made playback to play music.

# play button def buttonPlayClick (): # Select the music folder to play global folder if not folder: folder = tkinter.filedialog.askdirectory () if not folder: return global playing playing = True # create a thread to play music The current main thread is used to receive the user action t = threading.Thread (target=play) t.start () # disable and enable the corresponding button buttonPlay ['state'] =' disabled' buttonStop ['state'] =' normal' buttonPause ['state'] =' normal' buttonNext ['state'] =' normal' pause_resume.set ('Pause') buttonPlay = tkinter.Button (root) as appropriate Text='Play', command=buttonPlayClick) buttonPlay.place (Xerox 20, YB10, width=50, height=20) III. Stop function.

Very direct, directly stop playing, of course, change the state of the button is also a routine operation.

Def buttonStopClick (): global playing playing = False pygame.mixer.music.stop () musicName.set ('no music for the time being') buttonPlay ['state'] =' normal' buttonStop ['state'] =' disabled' buttonPause ['state'] =' disabled' buttonNext ['state'] =' disabled' global folder folder =''buttonStop = tkinter.Button (root, text='Stop') Command=buttonStopClick) buttonStop.place (Xero80, YBE10, width=50, height=20) buttonStop ['state'] =' disabled' IV, pause and resume

This is easy to understand, but also a direct off-the-shelf operation, plus a judgment, state change.

# suspend and resume, the two functions share one button def buttonPauseClick (): # global playing if pause_resume.get () = = 'Pause': pygame.mixer.music.pause () pause_resume.set (' Resume') elif pause_resume.get () = = 'Resume': pygame.mixer.music.unpause () pause_resume.set (' Pause') 5. Close

End the ready-made, and then close the form.

# Code executed when closing the program def closeWindow (): # modify the variable, end the loop in the thread global playing playing = False time.sleep (0.3) try: # stop playback, if stopped, # will throw an exception when it stops again So put pygame.mixer.music.stop () pygame.mixer.quit () except: pass root.destroy () 6 in the exception handling structure.
