• glob.glob:  a bit more than this. What it returns is a list of files with paths. So you also avoir the reconstruction of the path+file later on.
  
• directory: if not os.path.isdir(directory): mkdir(directory) so you avoid the error if the directory exists, and get a real error otherwise (access rights,  name is used by a file, etc...). You don't need makedirS since the parent already exist.
