In this article, we’ll show you how to install Pytube in Python and use it to download videos from YouTube.

Installing Pytube

Before we dive into the installation process, let’s cover the different ways to install Pytube. You can install it using pip, the Python package manager, or by downloading the source code.

Installing Pytube using a virtual environment

Using Pytube

Now that you have Pytube installed, you can use it to download videos from YouTube. Here’s an example of how to use it:

from pytube import YouTube



# Create a YouTube object

 yt = YouTube('https://www.youtube.com/watch?v=dQw4w9WgXcQ')



# Get the video title

title = yt.title



# Get the video URL

url = yt.streams.first().url



# Download the video

yt.streams.filter(only_audio=False).first().download()

This code creates a YouTube object, gets the video title and URL, and downloads the video.

Advanced Features

Pytube has several advanced features that you can use to customize your video downloads. Here are a few examples:

• Filtering: You can filter videos by various criteria, such as only_audio=False, which downloads the video even if it’s not audio-only.
• Resolution: You can specify the resolution of the video, such as 480p, 720p, or 1080p.
• Bitrate: You can specify the bitrate of the video, such as 128k or 512k.
• Quality: You can specify the quality of the video, such as 1080p or 720p.

Here’s an example of how to use these features:

from pytube import YouTube



# Create a YouTube object

yt = YouTube('https://www.youtube.com/watch?v=dQw4w9WgXcQ')



# Get the video title

title = yt.title



# Get the video URL

url = yt.streams.first().url



# Download the video

yt.streams.filter(only_audio=False, **{'resolution': '480p', 'bitrate': '128k', 'quality': '1080p'}).first().download()
