Help repeately prompting for directory name if it already exists.

[hikerguy62]

I took a look at that example but it wasn't making sense to me, so I found another snippet. I almost have it, but when I run the code below, it's giving me a syntax error and I don't know why:

import os
import shutil

newdir = input("Enter name of directory: ")
dir_exists = (os.path.exists("C:\\TIM\\SITES\\" + newdir))
newdir = ("C:\\TIM\\SITES\\" + newdir)
support_files = ("C:\\TIM\\SITES\\FILES FOR CONFIG BUILD\\")

while dir_exists:
	try:
		newdir = input("Enter name of directory: ")
		dir_exists = (os.path.exists("C:\\TIM\\SITES\\" + newdir))
	else:
		os.mkdir(newdir)

Here's what I see when I run it. I can't figure out what it doesn't like about the else statement:
C:\Users\tomel\Desktop>testing.py
File "C:\Users\tomel\Desktop\testing.py", line 14
else:
^
SyntaxError: invalid syntax
