I have a list with floating point number named a. When I print the list with print a. I get the result as follows.

[8.364, 0.37, 0.09300000000000003, 7.084999999999999, 0.469, 0.303, 9.469999999999999, 0.28600000000000003, 0.2290000000
000001, 9.414, 0.9860000000000001, 0.534, 2.1530000000000005]

Can I tell the list printer to print the format of “5.3f” to get better result?

[8.364, 0.37, 0.093, 7.084, 0.469, 0.303, 9.469, 0.286, 0.229, 9.414, 0.986, 0.534, 2.153]

    In [4]: print ['%5.3f' % val for val in l]
['8.364', '0.370', '0.093', '7.085', '0.469', '0.303', '9.470', '0.286', '0.229', '1.000', '9.414', '0.986', '0.534', '2.153']

    where l is your list.

    edit: If the quotes are an issue, you could use

    In [5]: print '[' + ', '.join('%5.3f' % v for v in l) + ']'
[8.364, 0.370, 0.093, 7.085, 0.469, 0.303, 9.470, 0.286, 0.229, 1.000, 9.414, 0.986, 0.534, 2.153]
