I think what you mean is (untested):

     algs = [AlgA, AlgB, AlgC, AlgD, AlgE]
     accs = sorted(((alg.accuracy(), alg.name()) for alg in algs),
                   reverse=True)
     for i,(alg_acc, alg_name) in enumerate(accs):
        print '%2d %5s %0.2f'% (i, alg_name, alg_acc)

This assumes a method alg.name() which tells you the name of the
algorithm.  I don't understand how you're converting the string 'AlgA'
to an algorithm object in your example above.
