Have ideas for how pytube can be improved? Feel free to open an issue or a pull request! # pytube *pytube* is a genuine, lightweight, dependency-free Python library (and command-line utility) for downloading YouTube videos. ## Documentation Detailed documentation about the usage of the library can be found at [pytube.io](https://pytube.io). This is recommended for most cases. If you want to hastily download a single video, the [quick start](#Quickstart) guide below might be what you're looking for. ## Description YouTube is the most popular video-sharing platform in the world and as a hacker, you may encounter a situation where you want to script something to download videos. For this, I present to you: *pytube*. *pytube* is a lightweight library written in Python. It has no third-party dependencies and aims to be highly reliable. *pytube* also makes pipelining easy, allowing you to specify callback functions for different download events, such as ``on progress`` or ``on complete``. Furthermore, *pytube* includes a command-line utility, allowing you to download videos right from the terminal. ## Features - Support for both progressive & DASH streams - Support for downloading the complete playlist - Easily register ``on_download_progress`` & ``on_download_complete`` callbacks - Command-line interfaced included - Caption track support - Outputs caption tracks to .srt format (SubRip Subtitle) - Ability to capture thumbnail URL - Extensively documented source code - No third-party dependencies ## Quickstart This guide covers the most basic usage of the library. For more detailed information, please refer to [pytube.io](https://pytube.io). ### Installation Pytube requires an installation of Python 3.6 or greater, as well as pip. (Pip is typically bundled with Python [installations](https://python.org/downloads).) To install from PyPI with pip: ```bash $ python -m pip install pytube ``` Sometimes, the PyPI release becomes slightly outdated. To install from the source with pip: ```bash $ python -m pip install git+https://github.com/pytube/pytube ``` ### Using pytube in a Python script To download a video using the library in a script, you'll need to import the YouTube class from the library and pass an argument of the video URL. From there, you can access the streams and download them. ```python >>> from pytube import YouTube >>> YouTube('https://youtu.be/2lAe1cqCOXo').streams.first().download() >>> yt = YouTube('http://youtube.com/watch?v=2lAe1cqCOXo') >>> yt.streams ... .filter(progressive=True, file_extension='mp4') ... .order_by('resolution') ... .desc() ... .first() ... .download() ``` ### Using the command-line interface Using the CLI is remarkably straightforward as well. To download a video at the highest progressive quality, you can use the following command: ```bash $ pytube https://youtube.com/watch?v=2lAe1cqCOXo ``` You can also do the same for a playlist: ```bash $ pytube https://www.youtube.com/playlist?list=PLS1QulWo1RIaJECMeUT4LFwJ-ghgoSH6n ``` ", Assign "at most 3 tags" to the expected json: {"id":"4580","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
