Say I have a file myfile.txt containing:

1   2.0000  buckle_my_shoe
3   4.0000  margery_door

How do I import data from the file to a numpy array as an int, float and string?

I am aiming to get:

array([[1,2.0000,"buckle_my_shoe"],
[3,4.0000,"margery_door"]])

I've been playing around with the following to no avail:

a = numpy.loadtxt('myfile.txt',dtype=(numpy.int_,numpy.float_,numpy.string_))

EDIT: Another approach might be to use the ndarray type and convert afterwards. 

b = numpy.loadtxt('myfile.txt',dtype=numpy.ndarray)

    array([['1', '2.0000', 'buckle_my_shoe'],
       ['3', '4.0000', 'margery_door']], dtype=object)
python numpy
