Python script to batch rename files via regex

batch_ren.py

import glob, os

# point path to directory containing the shows
# load episode titles into `ep.txt`
path = r"I:\Videos\show"

new_filenames = []
with open(path + '\\ep.txt', 'r') as f:
	for line in f:
		new_filenames.append(line)

fileglob = glob.glob(path + '\\*')
fileglob.remove(path + '\\ep.txt')

	ext = os.path.splitext(fileglob[i])[1]
	new_name = path + '\\' + new_filenames[i].strip() + ext
	print(fileglob[i] + ' -> ' + new_name)
	try:
		os.rename(fileglob[i], new_name)
	except: 
		continue
