YouTube Video Downloader

The objective of this project is to download any type of video or an entire playlist in a fast and easy way from YouTube in your device.

In this, user has to copy the youtube video/playlist URL that they want to download and simply paste that URL in the ‘paste link here’ section and click on the download button, it will start downloading the video. When video downloading finishes, it shows a message ‘DOWNLOADED!’ popup on the window below the download button.

Prerequisites

To implement this, we use basic concept of python, tkinter and pytube library.

• Tkinter is a standard GUI library and it is one of the easiest ways to build a GUI application.
• pytube used for downloading videos from youtube

To install the required modules run pip installer command on the command line:

pip install tkinter
pip install pytube

These are the following steps to build:

Step 1: Import libraries

Start the project by importing the required modules.

In this script implementation, we import Tkinter and pytube modules.

Step 2: Create display window

• Tk() used to initialize tkinter to create display window
• geometry() used to set the window’s width and height
• resizable(0,0) set the fix size of window
• title() used to give the title of window
• Label() widget use to display text that users can’t able to modify.
• root is the name of the window
• text which we display the title of the label
• font in which our text is written
• pack organized widget in block

Step 3: Create field to enter link

• link is a string type variable that stores the youtube video link that the user enters.
• Entry() widget is used when we want to create an input text field.
• width sets the width of entry widget
• textvariable used to retrieve the value of current text variable to the entry widget
• place() use to place the widget at a specific position

Step 4: Create function to start downloading

url variable gets the youtube link from the link variable by get() function and then str() will convert the link in string datatype.

The video is downloaded in the first present stream of that video by stream.first() method.

Button() widget used to display button on the window.

• text which we display on the label
• font in which the text is written
• bg sets the background color
• command is used to call the function

root.mainloop() is a method that executes when we want to run the program.
