[Python] Ich habe mit Tkinter einen Youtube Downloader erstellt.
1. Zuallererst
Mit Tkinter und Pytube habe ich ein GUI-Programm zum Herunterladen von Youtube-Videos erstellt.
2.1.pytyube
Informationen zur Installation und Verwendung von Pytube finden Sie unter dem folgenden Link.
https://python-pytube.readthedocs.io/en/latest/
2.2 Einführung in das Einfädeln
Führen Sie Multi-Threading in Freeze ein, während Sie die Reaktionsfähigkeit der Benutzeroberfläche beibehalten.
2.2.1. Generierungsreihenfolge
Design Thread in der folgenden Reihenfolge. Rückruffunktion der Schaltfläche Start → Thread-Generierungsmethode → Ausführungsmethode
from threading import Thread
#Rückruffunktion
def click_me(self):
self.create_thread()
#Thread-Generierungsmethode
def create_thread(self):
self.run_thread = Thread( target=self.method_in_a_thread )
self.run_thread.start()
print(self.run_thread)
#Ausführungsmethode
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. Anruf
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. Verwendung
Geben Sie die URL des herunterzuladenden Youtube-Videos ein und geben Sie den herunterzuladenden Ordner an.
Drücken Sie dann die Start-Taste.
Hier ist ein Beispiel für das Video von Herrn Samurai, das im Kommentarvideo des NHK-Taiga-Dramas "Kirin ga Kuru" einen Sprung nach vorne macht.

Nach dem Herunterladen sieht es so aus, als würde es auf dem Player abgespielt.
4. Zusammenfassung
- Verwenden Sie ein Modul namens Pytube, um Youtube herunterzuladen.
- Verwenden Sie Tkinter, um eine GUI zu erstellen.
- Einführung von Multithreading zur Aufrechterhaltung der Reaktionsfähigkeit der Benutzeroberfläche.
