1.Tout d'abord

En utilisant Tkinter et Pytube, j'ai créé un programme GUI pour télécharger des vidéos Youtube.

2.1.pytyube

Veuillez consulter le lien ci-dessous pour savoir comment installer et utiliser Pytube.

https://python-pytube.readthedocs.io/en/latest/

2.2. Introduction du filetage

Introduisez le multi-threading pour Freeze tout en maintenant la réactivité de l'interface graphique.

2.2.1. Ordre des générations

Concevez le fil dans l'ordre suivant. Fonction de rappel du bouton Démarrer → Méthode de génération de thread → Méthode d'exécution

from threading import Thread

#Fonction de rappel
def click_me(self):
    self.create_thread()

#Méthode de génération de thread
def create_thread(self):
    self.run_thread = Thread( target=self.method_in_a_thread )
    self.run_thread.start()
    print(self.run_thread)

#Méthode d'exécution
def method_in_a_thread(self):
    print('New Thread is Running.')
    self.get_youtube( self.URL_name.get(), self.Folder_name.get())

2.2.2. Appel

self.btn_Start = tk.Button(self.frame_form, text = 'Start')
self.btn_Start.configure( font= self.font02 )
self.btn_Start.grid( column=1, row=2, padx=20, pady=20, sticky= tk.W + tk.E )
self.btn_Start.configure( command = self.click_me)

3. Comment utiliser

Entrez l'URL de la vidéo Youtube à télécharger et spécifiez le dossier à télécharger. Appuyez ensuite sur le bouton Démarrer. Voici un exemple de la vidéo de M. Samurai, qui fait un bond en avant dans la vidéo de commentaire du drame NHK Taiga "Kirin ga Kuru". https://www.youtube.com/watch?v=NYUYYMs-5UY Après le téléchargement, il semble qu'il sera lu sur le lecteur.

4. Résumé

Utilisez un module appelé Pytube pour télécharger Youtube.
Utilisez Tkinter pour créer une interface graphique.
Introduit le multi-threading pour maintenir la réactivité de l'interface graphique.
