title: How can I access and change the tag description property of a JPEG image in the Windows 7 file explorer through the use of Python?
body: <p>I am having a difficult time understanding how I can change the Tags of a JPEG file through Python. The "Tags" I'm referring to are those under the description properties of any arbitrary file, where comments, subjects, and ratings would also be found. I am uncertain whether or not there is a .os function similar to the filename rename function which can do this, or if this kind of operation of changing the tags would fall under the category of JPEG Metadata/EXIFDATA manipulation. </p>
  
  <p>Say, for example, I want to add 3 tags to a JPEG image through Python, those being the tags BLUE, SQUARE, and 9. Manually I would go to the file, access the description properties either by right-clicking the file to view its tags, or clicking the bottom bar menu, and click tags to then input BLUE, SQUARE, and 9 into the text box, with a semicolon after each individual tag. With Python, I would need a script that could inject those individual tags into the description properties of the JPEG to make the process less painful if I were to do this iteratively for multiple JPEG files.</p>
  
  <p>I doubt this would require any heavy-handed knowledge of programing with Python, but at the same time the specificity of my issue seems to elude an easy resolution. I can't seem to find a semi-clear or straightforward answer, as I'm a bit of a greenhorn when it comes to programing with python in general. </p>
  
  <p>Any help would be very, very useful. I am using Python 3.5.2. by the way.</p>
