Hash md5 comparison

Postby greg2 » Mon Apr 14, 2014 9:20 am

My professor give me the assignement to modify a python program but I'm not very good with programming and I'm looking for help.. The program now compares different md5 hash and if it finds it two that are the same it moves it to another folder.. I must modify the program so that instead of moving it to another folder it delete the hash md5 who are the same..
Code: Select all
Scan, find and move to output dir the duplicated files
hashes = set()
for dirname, dirnames, filenames in os.walk(dirName):
    #for subdirname in dirnames:
    #    print os.path.join(dirname, subdirname)

    # print path to all filenames.
    for filename in filenames:
        #print os.path.join(dirname, filename)
        hash_digest = md5_for_file(os.path.join(dirname, filename))
        if hash_digest in hashes:
            os.rename(os.path.join(dirname, filename),os.path.join(outputdir, filename))
            #os.remove(os.path.join(dirname, filename))

I think i should replace this part os.path.join(outputdir, filename)) with os.remove(os.path.join(dirname, filename)) but it seems too easy and I'm not very sure about it... Any help would be appreciated.. Maybe it's a stupid question but I don't really know much about Python.. Thanks

Yes, that should work.
