[Tutor] Saving and loading data to/from files

[Daryl G]

Hi,  I am having difficulty in saving and loading data that I created in a 
simple Address book program. I  am using 3 list variables for First and Last 
name and phone number and an interger that counts the total number of 
entries.  I first tried using the 'write' but that wouldn't work with lists. 
I discovered the pickle module and
I am able to save my data, but when I load it back up and then try to view 
it in my program, its not there.

variables
import pickle, string

F_Name=[]
L_Name=[]
PH_num=[]
total=0

#savedata method
def savedata():
    filename= raw_input("Enter the name you wish to give this address book: 
")
    object=(F_Name, L_Name, PH_num, total)
    file=open(filename, 'w')
    pickle.dump(object, file)

#opendata method
def opendata():
    filename=raw_input("Enter the name of the Addressbook you wish to open: 
")
    file = open(filename,'r')
    (F_Name,L_Name, PH_num, total)=pickle.load(file)


What am I doing wrong?
Another question that I have is how do I format data that I want to display 
in specific
columns in standerd output, like that can be done in C ?
Thanks
Daryl
