Try the 'pickle' module:

>>> import pickle
>>> stooges = ['val1', 'val2', 1, [['val2_1', 'val2_2', 0], ['val2_1',
... 'val2_2', 0]]]
>>> save_file = 'stooges.dat'
>>> output = open(save_file,'wb')
>>> pickle.dump(stooges, output)
>>> output.close()
>>> input = open(save_file,'rb')
>>> stooges2 = pickle.load(input)
>>> input.close()
>>> stooges2
['val1', 'val2', 1, [['val2_1', 'val2_2', 0], ['val2_1', 'val2_2', 0]]]
