How to rename a bunch of files using python?

I am a complete beginner in python. I need to rename a bunch of files with dates in the name. The names all look like:

I would like them to start with the date rather then front, left, or right, so that front 7.25.16 becomes 7.25.16 front.

I have tried using regular expressions and os.walk and I have run into troubles with both. Right now I am just trying to print the file names to prove os.walk is working. Right now my code looks like this:

import re, shutil, os

K = re.compile(r"(\d+.\d+.\d+)")
RE_Date = K.search("front 7.25.16")

for root, dirs, filenames in os.walk("path"):
    for filename in filenames:
        print ("the filename is: " + filename)
    print ("")

Any advice would be greatly appreciated.

Check this example to rename file as per your need.

import os

filenames = ["front 7.25.16.jpg", "left 7.25.16.jpg", "right 7.25.16.jpg"]

for file_name in filenames:
    x = file_name.split(' ')[0]
    y = file_name.split(' ')[1]
    new_name = '{} {}{}'.format(os.path.splitext(y)[0], x, os.path.splitext(y)[-1])
    print new_name

output:

7.25.16 front.jpg
7.25.16 left.jpg
7.25.16 right.jpg

In your code your can use os.rename for rename files

import os

for root, dirs, filenames in os.walk("path"):
    for file_name in filenames:
        x = file_name.split(' ')[0]
        y = file_name.split(' ')[1]
        new_name = '{} {}{}'.format(os.path.splitext(y)[0], x, os.path.splitext(y)[-1])
        file_path = os.path.join(root, file_name)
        new_path = os.path.join(root, new_name)
        os.rename(file_name, new_path)
