Is it possible to make rules for file manager / Python

Question

I want to ask is it possible to make a rules for file managing program. For instance, if i want to move certain file in Image folder to move only .png and .img files. How i should declare rule in the configuration file that program would understand? If you would need I would my code gladly upload it. Which libraries i would need to use or give certain examples? Thank you in advance!

    print ("Log file already exist")
else:
    logging.basicConfig(filename='app.log', filemode="w", format='%(name)s - %(levelname)s - %(message)s ')
    print ("Log file doesn't exist, so new one was created")


LOG_for="%(asctime)s, %(message)s"

logger=logging.getLogger()
logger.setLevel(logging.DEBUG)


# move file function

                                          filetypes = config.select.ft)

    destination =filedialog.askdirectory()
    dest = os.path.join(destination,filename)
    if(source==dest):
        mb.showinfo('confirmation', "Source and destination are the same, therefore file will be moved to Home catalog")
        newdestination = Path("/home/adminas")

        logging.shutdown()
        logging.basicConfig(filename='app.log', filemode="a", format=LOG_for) 
        logging.info('File *' + filename + '* was moved to new destination: ' + newdestination)

It sounds like you want to move only files of a specific type (e.g. .png or .img). You can do this based on the file name itself using endswith:

if source.endswith('.png'):
   shutil.move(source, newdestination)

You can see an example in this answer Converting images to csv file in python where the function walks through a directory and creates a list of files that all share the same file extension.

Note that this code only checks the file extension, not the actual file itself.

Now, say you only want to apply this rule to a folder called "Images", then you can still use string manipulation. You might use contains:

if source.contains("Images"):
    # do something

Alternatively, if you know your file path might contain the word "Images" more than once, you can use os.path.split(path) to split the path into "path" and "file", and then again on the resulting head to split it into "path" and last folder. Compare the resulting tail to Images:

h, t = os.path.split(source)
h2, t2 = os.path.split(h)
if t2.contains("Images"):
    #do something

There are other ways to do this using the os.path functions and you will want to investigate these.
