Create Python YouTube Downloader using Pytube

YouTube Video Downloader is an application that we require many times. The user can use this application to directly download a video by entering the link in this application. Let’s try building this YouTube Video Downloader project with the help of Python.

About YouTube Video Downloader

The objective of a YouTube Video Downloader is to let the user download a video available on Youtube. In the YouTube Video Downloader, one has to enter the link of YouTube video and the video gets downloaded and saved in the system. You can download as many videos as you want with it.

Python Youtube Video Downloader Project Details

In this project, we are going to create a GUI Window that will have the following widgets:

1. An Entry Box – To enter the link of a YouTube video.

2. Checkboxes – To check the quality/resolution of the video.

3. Button – To download the video.

Using this project, you can download a video from YouTube in any quality that you desire.

Project Prerequisites

To develop this project, we need to pre install the following modules:

1. Tkinter Module – this is the module that helps us create an easy GUI using Python.

2. Pytube Module – this is the module that will help us download videos from YouTube.

Steps to Build the Project

Let us look at the steps to build the YouTube Video Downloader Project:

1. Importing the Modules

2. Creating the GUI and adding components.

3. Download Function

1. Importing the Modules:

#importing modules
from pytube import YouTube
from tkinter import *
import tkinter as tk

• We are importing the required modules.

2. Creating the GUI Window and Adding Components:

# Create an instance of tkinter frame or window
window=Tk()
# Set the size of the tkinter window
window.geometry("700x350")
window.title("PythonGeeks")#give title to the window
Label(window, text="YOUTUBE VIDEO DOWNLOADER",bg='grey', font=('Calibri 15')).pack()# a label
Label(window, text="Enter the link to download", font=('Calibri 12')).pack()# a label
Entry(window,textvariable=text,width=50).pack()#entry field
Checkbutton(text='360p',onvalue=18, offvalue=0,variable=res1).pack()#creating checkbox
Checkbutton(text='720p',onvalue=22, offvalue=0,variable=res2).pack()#creating checkbox
Checkbutton(text='1080p',onvalue=37, offvalue=0,variable=res3).pack()#creating checkbox
#creating a button
Button(window,text="Download",bg='green',command=downloader).pack()

1. Tk() – The Tk() method helps us create a blank GUI Window.

2. geometry() – The geometry() method defines the size of the GUI Window.

3. Title – The title() method gives an appropriate title to the GUI Window.

4. Label() -The label() method creates a widget on the GUI Window which helps us display a piece of text. You can specify the following attributes inside a Label() method:

• Text – what text to be displayed.
• Bg – Background colour.
• Fg- Foreground colour.
• Font – The font of the text

5. Entry() – The Entry() method helps us create an entry field on the GUI Window. We can specify the following things inside the Entry() method:

• Width – The width of the entry field.
• Textvariable – what variable will be associated with the entry field.

6. Checkbutton() – The CheckButton() method creates check buttons on the GUI Window. For one checkbutton the method is used one. Inside a checkbutton() method, we can specify the following things:

• Onvalue – The value assigned when the check button is checked.
• Text – The text visible with the checkbutton.
• Textvariable – The variable associated with the checkbutton.

7. Button() – The button() method helps us create a Button on the GUI Window. Inside a Button() method, we can specify the following attributes:

• Text – Text on the button.
• Command – The function to be evoked when the button is clicked.
• Bg – Colour of the button.
• Fg – Foreground colour.

8. pack() – pack function s to display all the widgets on the GUI Window.

3. Download Function:

def downloader():#defining a function
    global res#global variable
    t=text.get()#getting the value
    video = YouTube(t)
 
    if res1==18:
        res=18
    elif res2==22:
        res=22
    elif res3==37:
        res=37
 
    video_streams = video.streams.filter(file_extension = 'mp4').get_by_itag(res)
    video_streams.download(filename = "Untitled", output_path = "video_path")
    Label(window,text="Downloaded Successfully").pack()

• We have created the downloader function to download a video from YouTube.
• We have created a global variable res.
• get() – Using the get() method, we get the value entered in the entry field.
• YouTube() – Extracts the video from YouTube.
• video.streams.filter() – Is to set the filter to the video.
• get_by_itag() – Is to specify the resolution of the video.
• download() – Is to download the video.

window.mainloop()

• mainloop() – mainloop() function displays our window and the components on it.

Python YouTube Downloader Output

Summary

Hurray! We have successfully completed the YouTube Video Downloader Project in Python. We learned how to use the Tkinter Module and Pytube Module. You can add more resolution options to it.

I hope you enjoyed building this project with PythonGeeks!
