How To Use Python To Search For File By Name, Find The Latest Modified, Find Next File And Repeat Steps?

I have a folder that has many DWG files and an example of some files might be LINCOLN 09-17 #1-29H ASBUILT 10-26-2010.dwg LINCOLN 09-17 #1-29H FINAL 01-20-2011.dwg CAMPBELL 07-17 #

Solution 1:

You need to go searching for the suitable files, and remeber the newest of each one as you come accross it. Then report the latest.

In pseudo-code.

dates = dict() // key is filename, valueisdatefor  subdir,dirs, files in os.walk(startdir):
if filename ends with "dwg":
     if filename contains "FINAL":
          date= getDate from filename 
          if dates contains filename
              prev = dates(filename)
          else 
              prev = zero date// a value so next line tests true always
          if date> prev:
             dates(filename) =date//else previous is younger, so skip//else draft oras built andskip//else filename not dwg andskipfor dates.values as v
    print v
