I have taken into advice what was mentioned earlier, but I have run into a snag in which I am getting the wrong output from my class.
> python matchlist.py ./test ./test/list.txt output: ['list.txt', 'test1.txt', 'test2.txt'] set(['test1']) ['', '/', 't', 'e', 's', 't'] The first line of output correctly displays the list of file names in the argv[1] directory. The second line of output correctly displays the set list from readlines on list.txt. The third line of out put should be the same as the 1st line minus the extenxions in the file names. Here is the code: import os from sys import argv class MatchList: def __init__(self, dirList, fileList): self.dirList = os.listdir(dirList) self.fileList = set(open(fileList, 'r').readlines()) self.matchList = [] self.retList = [] self.rut = [] def match(self): for item in dirList: rut = os.path.splitext(item)[0] self.matchList.append(rut) print self.matchList def testPrint(self): print self.dirList print self.fileList self.match() if __name__ == '__main__': if len(argv) == 3: dirList = argv[1] fileListName = argv[2] match = MatchList(dirList, fileListName) match.testPrint() What I want to happen is produce a list of the filenames minus the extensions so that I can set that list. Once that list is set, I can subtract the set list from the readlines function and then use the difference list to determine what files are missing form the directory. Thanks in advance:) SA P.S. Is there a special way to include code in my postings so that it looks different from the rest of the text in the posting? -- http://mail.python.org/mailman/listinfo/python-list
