Answer 1

I had a similar problem, but I wanted to append text to the beginning of the file name of all files in a directory and used a similar method. See example below:

folder = r"R:\mystuff\GIS_Projects\Website\2017\PDF"

import os


for root, dirs, filenames in os.walk(folder):


for filename in filenames:  
    fullpath = os.path.join(root, filename)  
    filename_split = os.path.splitext(filename) # filename will be filename_split[0] and extension will be filename_split[1])
    print fullpath
    print filename_split[0]
    print filename_split[1]
    os.rename(os.path.join(root, filename), os.path.join(root, "NewText_2017_" + filename_split[0] + filename_split[1]))
