The General Regular Expression Parser - at least that's one of the explanations. (Another is that it is the ed search command, and there are at least two more, it's part of the Unix mythology, debated for at least 30 years! :-) More pragmatically it is the standard Unix tool for searching text files for strings. Its available on other OS too thanks to GNU. Thus grep "NEWI" *.py will find all the occurences of NEWI in your python files. (grep -f will list only the files containing it.) If you use emacs or vi as your editor you can get the editor to step through the results in the same way as you step through the compilation errors after a make... You can search for sophisticated regex patterns and include or exclude patterns etc. grep should be a basic tool of any programmer regardless of language used or OS. > But if I can't get the program to initialize this 'NEWI' then > I don't know how any values can come from it. Thats the critical factor here. You need to initialise the dictionary in the first place. I notice from another post tat its being loaded from a pickle file. Try looking to see where it gets "dumped" to the file, that might help (grep again!) If the dump only happens when the program closes down then maybe just writing some default values on the first load of the program will do - thats where the get() method comes in again... It looks suspiciuously to me as if this NEWI key is some extra feature thats been added to the code and the initialisation code has not been updated to cope. Thats a common error especially in programs where the initialisation is in another program that only got run once a long time ago!
