Count the number of regex matches within a subreddit

Project description


Count the number of regular expression matches within a subreddit.


This package is a wrapper for psaw. It allows the user to easily count the number of matches of a regular expression within a certain period of time within a subreddit. The regular expression matches are stored in a dictionary, with the matches themselves being the keys, and the number of occurrences as the values.
