Show progress in for loop by counting the images already processed [Python]

Question

I would like to count the amount of pictures already converted. Therefore I have to modify print('converting') somehow.

def convert(self):          
        directory = [fn for fn in os.listdir(self.destination_folder) 
                      if any(fn.endswith(ext) for ext in included_extensions)]
        for item in directory:
            if item.endswith('.jpg' ): 
                img = Image.open(self.destination_folder + item)
                pathx = self.destination_folder + item
                convert='mogrify -virtual-pixel Black +distort Plane2Cylinder 53 -crop 2060x2060+620+202 %s' %pathx
                
                subprocess.run(convert, env={'PATH': path_cur})
                print('converting')

The output should be something like. xxx should be the total amount of files in directory.

converting [1/xxx]
converting [2/xxx]
converting [3/xxx]
...

How can I get this output?

Without having access to your data, something perhaps like:

def convert(self):          
        directory = [fn for fn in os.listdir(self.destination_folder) 
                      if any(fn.endswith(ext) for ext in included_extensions)]

        train_length = len(directory)
        counter = 1

        for item in directory:
            if item.endswith('.jpg' ): 
                img = Image.open(self.destination_folder + item)
                pathx = self.destination_folder + item
                convert='mogrify -virtual-pixel Black +distort Plane2Cylinder 53 -crop 2060x2060+620+202 %s' %pathx
                
                subprocess.run(convert, env={'PATH': path_cur})
                print('converting', '[',counter,'/', train_length, ']')
                counter += 1

The enumerate method in the comments above is better.
