Coursera Parser

Description

This program allows you to download courses from Coursera.

Program can download video lessons, accompanying materials(mp4 in different resolutions, subtitles), quiz assignments, and other types of lessons in the form of screenshots and PDF files.

How to use

There are three commands: login, get-course-data, and download-course. If you want to download a course, you must follow these instructions:

  1. Sign in to your account using the login command.
  2. Download information about the course using the get-course-data command into a JSON file.
  3. Finally, apply the download-course command to your JSON file.

Examples

  1. pip install -r requirements.txt
    This command will install the required libraries.

  2. python main.py login --email <EMAIL> --password <PASSWORD>
    This command saves your cookies into ./cookies/last-saved.pkl. Additionally, you can use the parameter --file-name <FILENAME>.pkl to save your cookies to ./cookies/<FILENAME>.pkl.

  3. python main.py get-course-data -u <url>
    As a result of this command, all data about the course will be downloaded to ./download/<COURSE_NAME>.json.
    Usually, <url> looks like https://www.coursera.org/learn/<COURSE_NAME>/home/week/1. You don't need to apply this command for all weeks. The algorithm looks at the first page, calculates the number of weeks, and parses all courses.
    If you use --file-name in the login command, then you can add --cookies <FILENAME>.pkl to select a different session.

  4. python main.py download-course -p <path_to_data>.json After applying this command, all course data will be downloaded to ./downloads/<COURSE_NAME>/.
    Like previous section, there you also can use --cookies to select appropriate session.

Issues:

  1. Sometimes Coursera changes its website code, so the parser may break until I update the web element paths.

  2. If you see an exception like this "AssertionError: Unrecognized lesson type Peer-graded Assignment" (where Peer-graded Assignment may be replaced by another lesson type), simply set DEBUG = False in defines.py.

  3. You can only use the English version of the website. To change the website language, go to Settings.
