创建用于使用Python下载YouTube视频的GUI

先决条件： Python GUI – Tkinter

YouTube是一个非常受欢迎的视频共享网站。从YouTube下载视频/播放列表是一项繁琐的任务。通过Downloader下载该视频或尝试从随机网站下载该视频, 这会增加舔你个人数据的风险。使用Python Tkinter包, 此任务非常简单, 高效, 安全。几乎没有群码可以为你下载视频。为此, 有两个Python库–Tkinter和pytube.

所需模块

pytube：

pytube是一个轻量级, 易于使用, 无依赖的Python库, 用于从web.pytube下载视频, 而不是自动配置的库。你需要先安装它, 然后才能使用它。当你拥有pip时, 安装pytube很容易。在终端或命令提示符中, 键入以下命令以安装pytube。

如果你使用的是Mac OS X或Linux, 则以下两个命令之一可能会为你工作：

pip安装pytube git clone git：//github.com/NFicano/pytube.git pytube | cd pytube | python setup.py安装

如果你在Window的

pip install pytube3

Tkinter

:

Tkinter是Python与Tk GUI工具包的绑定。它是Tk GUI工具包的标准Python界面, 或者简单地说Tkinter用作Python图形用户界面。 Tkinter是本机库, 使用时无需外部安装, 只需导入即可。

下面是实现。

# Importing necessary packages
import tkinter as tk
from tkinter import *
from pytube import YouTube
from tkinter import messagebox, filedialog
  
  
# Defining CreateWidgets() function
# to create necessary tkinter widgets
def Widgets():
     link_label = Label(root, text = "YouTube link  :" , bg = "#E8D579" )
     link_label.grid(row = 1 , column = 0 , pady = 5 , padx = 5 )
   
     root.linkText = Entry(root, width = 55 , textvariable = video_Link)
     root.linkText.grid(row = 1 , column = 1 , pady = 5 , padx = 5 , columnspan = 2 )
   
     destination_label = Label(root, text = "Destination    :" , bg = "#E8D579" )
     destination_label.grid(row = 2 , column = 0 , pady = 5 , padx = 5 )
   
     root.destinationText = Entry(root, width = 40 , textvariable = download_Path)
     root.destinationText.grid(row = 2 , column = 1 , pady = 5 , padx = 5 )
   
     browse_B = Button(root, text = "Browse" , command = Browse, width = 10 , bg = "#05E8E0" )
     browse_B.grid(row = 2 , column = 2 , pady = 1 , padx = 1 )
   
     Download_B = Button(root, text = "Download" , command = Download, width = 20 , bg = "#05E8E0" )
     Download_B.grid(row = 3 , column = 1 , pady = 3 , padx = 3 )
  
# Defining Browse() to select a 
# destination folder to save the video
  
def Browse():
     # Presenting user with a pop-up for
     # directory selection. initialdir 
     # argument is optional Retrieving the
     # user-input destination directory and
     # storing it in downloadDirectory
     download_Directory = filedialog.askdirectory(initialdir = "YOUR DIRECTORY PATH" )
   
     # Displaying the directory in the directory
     # textbox
     download_Path. set (download_Directory)
  
# Defining Download() to download the video
def Download():
      
     # getting user-input Youtube Link
     Youtube_link = video_Link.get()
      
     # select the optimal location for
     # saving file's
     download_Folder = download_Path.get()
   
     # Creating object of YouTube()
     getVideo = YouTube(Youtube_link)
   
     # Getting all the available streams of the
     # youtube video and selecting the first
     # from the
     videoStream = getVideo.streams.first()
   
     # Downloading the video to destination 
     # directory
     videoStream.download(download_Folder)
   
     # Displaying the message
     messagebox.showinfo( "SUCCESSFULLY" , "DOWNLOADED AND SAVED IN\n" 
                         + download_Folder)
  
# Creating object of tk class
root = tk.Tk()
   
# Setting the title, background color 
# and size of the tkinter window and 
# disabling the resizing property
root.geometry( "600x120" )
root.resizable( False , False )
root.title( "YouTube_Video_Downloader" )
root.config(background = "#000000" )
   
# Creating the tkinter Variables
video_Link = StringVar()
download_Path = StringVar()
   
# Calling the Widgets() function
Widgets()
   
# Defining infinite loop to run
# application
root.mainloop()
