# This program was created by jpark. It scrapes reddit for valid accounts if one already knows the username besides numbers at the end. 
# Swap the characters inside the quotation marks for the variable s.
# Inside the quotation marks, type the part of the username that you already know (letters only). For the value of the number inside the string (i + _),
# Set the starting number for this scraper.
