How to grab all files in a folder and get their MD5 hash in python?

I'm trying to write some code to get the md5 of every exe file in a folder.

My problem is that I don't understand how to do it. It works only if the folder contains only one file. This is my code:

import glob
import hashlib
file = glob.glob("/root/PycharmProjects/untitled1/*.exe")

newf = str (file)
newf2 =  newf.strip( '[]' )
newf3 = newf2.strip("''")

with open(newf3,'rb') as getmd5:
    data = getmd5.read()
    gethash= hashlib.md5(data).hexdigest()
    print gethash

And I get the result:

a7f4518aae539254061e45424981e97c

I want to know how I can do it to more than one file in the folder.
