I have an interesting problem I'm trying to solve. I have a solution almost working, but it's super ugly, and know there has to be a better, cleaner way to do it.
I have a list of path names that have this form: /dir0/dir1/dir2/dir3/dir4/dir5/dir6/file I need to find all the file names (basenames) in the list that are duplicates, and for each one that is a dup, prepend dir4 to the filename as long as the dir4/file pair is unique. If there are multiple dir4/files in the list, then I also need to add a sequence number based on the sorted value of dir5 (which is a date in ddMONyy format). For example, if my list contains: /dir0/dir1/dir2/dir3/qwer/09Jan12/dir6/file3 /dir0/dir1/dir2/dir3/abcd/08Jan12/dir6/file1 /dir0/dir1/dir2/dir3/abcd/08Jan12/dir6/file2 /dir0/dir1/dir2/dir3/xyz/08Jan12/dir6/file1 /dir0/dir1/dir2/dir3/qwer/07Jan12/dir6/file3 Then I want to end up with: /dir0/dir1/dir2/dir3/qwer/09Jan12/dir6/qwer_01_file3 /dir0/dir1/dir2/dir3/abcd/08Jan12/dir6/abcd_file1 /dir0/dir1/dir2/dir3/abcd/08Jan12/dir6/file2 /dir0/dir1/dir2/dir3/xyz/08Jan12/dir6/xyz_file1 /dir0/dir1/dir2/dir3/qwer/07Jan12/dir6/qwer_00_file3 My solution involves multiple maps and multiple iterations through the data. How would you folks do this? -- http://mail.python.org/mailman/listinfo/python-list
