Fully functional PyQt address book

Hi, just wanted to post the code for a program I did a little while ago. It's an address book that let's you store some data about a person. The buttons are in tile-style and a button get's added dynamically when you create a new contact. Have fun.

import sys,pickle,time
from PyQt4 import QtGui, QtCore


f = open("contacts.txt","rb")
try:
    contacts = pickle.loads(f.read())
    print("1")
except:
    print("2")
    contacts = {}
finally:
    f.close()
