What do you mean 'it won't run'?  Do you get an error with Traceback?

I glanced at your code, and your dictionary ends like this: , 'X':'A',
'Y':'B', 'Z':'C',

There is no closing brace

OK,

    File "./crypto.py", line 6
      def encrypt():
        ^
SyntaxError: invalid syntax

First, don't reply to me, reply to the group.  That might mean
choosing reply all.

So, your first problem is that the dictionary isn't closed.  This is
causing the error at line 6

fix that and find your next error.  It looks like there are lots of them

With such a small file you would do better to just post the code
directly.  That way if people see problems they can point them out in
the body of the reply

good luck

#!/usr/bin/env python3

import random
values = {'a':'d', 'b':'e', 'c':'f', 'd':'g', 'e':'h', 'f':'i', 'g':'j',
'h':'k', 'i':'l', 'j':'m', 'k':'n', 'l':'o', 'm':'p', 'n':'q', 'o':'r',
'p':'s', 'q':'t', 'r':'u', 's':'v', 't':'w', 'u':'x', 'v':'y', 'w':'z',
'x':'a', 'y':'b', 'z':'c', 'A':'D', 'B':'E', 'C':'F', 'D':'G', 'E':'H',

def encrypt():
     textInputE = input('Please enter the text you wish to encrypt: ')
     textInputE.list()
     for Eletter in textInputE.list():
         try:
             print (values[Eletter])
         except KeyError:
             print ('Sorry, that input couldn\'t be parsed as text. Try
again.')
             input('Press Enter')
def decrypt():
     textInputD = input('Please enter the numbertext you wish to decrypt')
     textInputD.list()
     for Dletter in textInputD.list():
         try:
             print (values[Dletter])
         except KeyError:
             print ('Sorry, that input couldn\'t be parsed as numbertext from
our cipher. Please try again.')
             input('Press Enter')

while True:
     EorD = input('Encrypt or Decrypt: ')

so are you sure the line above is really what you have in your code?
check the quotes

     if EorD == 'Encrypt' or EorD == 'encrypt':
         encrypt()
     elif EorD == 'Decrypt' or EorD == 'decrypt':
         decrypt()
     else:
         print('Encrypt or Decrypt?')

Thanks, I am not quite used to this client yet. The next error is:

Traceback (most recent call last):
   File "crypto.py", line 25, in <module>
     EorD = input('Encrypt or Decrypt: ')
   File "<string>", line 1, in <module>
NameError: name 'Encrypt' is not defined

OK, I have put it back into Python 2.7, and now I get:
Traceback (most recent call last):
  File "crypto.py", line 27, in <module>
    encrypt()
  File "crypto.py", line 7, in encrypt
    textInputE.list()
AttributeError: 'str' object has no attribute 'list'
