#A parser for the CC-Cedict. Convert the Chinese-English dictionary into a list of python dictionaries with "traditional","simplified", "pinyin", and "english" keys.
#Make sure that the cedict_ts.u8 file is in the same folder as this file, and that the name matches the file name on line 13.
#Before starting, open the CEDICT text file and delete the copyright information at the top. Otherwise the program will try to parse it and you will get an error message.
#Characters that are commonly used as surnames have two entries in CC-CEDICT. This program will remove the surname entry if there is another entry for the character. If you want to include the surnames, simply delete lines 59 and 60.
#This code was written by Franki Allegra in February 2020.
