Reddit Data Collector

Reddit Data Collector is a Python package that allows a user to collect post and comment data from Reddit. It is built on top of the Python module PRAW, which stands for "The Python Reddit API Wrapper". It aims to make it very simple for a user to collect data from Reddit for further analysis (e.g. Natural Language Processing), without having to learn the inner workings of PRAW or the Reddit API.

The main functionalities provided by the package currently include:

1. Ability to collect a sample of post data and comment data from Reddit by simply providing the subreddit names that you wish to collect data from.

2. Ability to convert that data into a pandas DataFrame in order to inspect it and save it for further use.

3. Ability to seamlessly update an existing .csv file that contains some sample data collected with the package in the past, with some new sample data that is also collected with the package.

It is currently maintained by Nico Van den Hooff.

Potential Ideas for Contribution

• Add ability to collect images from Reddit posts that contain them.
• Add author information to post and comment data, currently the Reddit API is inconsistent with suspended and deleted author data, so this functionality has not been built in yet.

Testing

After installation, you can launch the test suite, which is contained in the tests/tests.py. Note that you will have to have pytest >= 6.2.5 installed. You can launch the test suite by following these steps from the projects root directory:

1. Open up tests.py with the following command:

open tests/tests.py

Comment out lines 24 to 30. Change the values in DataCollector() in line 32 to your Reddit credentials.

2. Run the following command:

pytest tests/test.py

Project History

The project was started in January 2022 by Nico Van den Hooff as a side project while he was completing the UBC Master of Data Science Project. Nico wanted to obtain a sample of posts and comments from Reddit, but noticed that while PRAW existed and provided seamless access to Reddit's API, there was no package available that allowed for a simple method to collect this data.

Inspiration

Certain sections of this README file was inspired by the scikit-learn README.
