pickle handling multiple objects ..

[Smiley 4321]

If I have a sample python code to be executed on Linux. How should  I
handle multiple objects with 'pickle' as below -

-------
#!/usr/bin/python

import pickle

#my_list = {'a': 'Apple', 'b': 'Mango', 'c': 'Orange', 'd': 'Pineapple'}
#my_list = ('Apple', 'Mango', 'Orange', 'Pineapple')
my_list = ['Apple', 'Mango', 'Orange', 'Pineapple']
#my_list = ()
output = open('readfile.pkl', 'wb')
pickle.dump(my_list, output)
output.close()

my_file = open('readfile.pkl', 'rb')
my_list2 = pickle.load(my_file)
my_file.close()

print my_list
print my_list2
-----

This code works fine but now I have to handle multiple objects?
