copy and rename files starting at a specific integer value in python

My codes work but for a few pain points that perhaps you can help me understand. I want to copy files from one directory to another and rename them at the same time. for example:

c:\path\
octo.jpeg
novem.jpeg
decem.jpeg

to:

c:\newpath\
001.jpeg
002.jpeg
003.jpeg

The codes I wrote from a cursory google search are as follows but I'm not sure why I need the 'r' in the path variables. The 'files = os.listdir(srcPath)' line I'm sure I don't need. This will move the files and renames them using the 'count' variable in the for loop but I want to name each file starting at a specific number, say 65. Should I use the shutil library and copy2 method to first copy the files and then rename or is there an easier way?

import os
from os import path

srcPath = r'C:\Users\Talyn\Desktop\New folder\Keep\New folder'
destPath = r'C:\Users\Talyn\Desktop\New folder\Keep\hold'
#files = os.listdir(srcPath)

def main():

    for count, filename in enumerate(os.listdir(srcPath)):

        dst = '{:03d}'.format(count) + ".jpeg"
        
        os.rename(os.path.join(srcPath, filename), os.path.join(destPath, dst))


if __name__=="__main__":
    
    main()

From the official Python Docs:

Both string and bytes literals may optionally be prefixed with a letter 'r' or 'R'; such strings are called raw strings and treat backslashes as literal characters.

The r is telling python interpreter to treat the backslashes(\) in the path string as literal characters and not as escaping characters.

For naming the files from a specific number:

dst = '{:03d}'.format(count + your_number) + ".jpeg"

Using copyfile from shutil

copyfile(srcPath + filename, destPath + dst)
