No, to my knowledge that doesn't exist in numpy.  The closest I can
quickly think off is:

In [14]: np.core.defmatrix._convert_from_string('3 4; 5 6')
Out[14]: [[3, 4], [5, 6]]

this _convert_from_string is used by the np.matrix() constructor, but
NOT by the default array one.

You should keep in mind the issues that exist with potential loss of
precision when editing the text representation of floating point
numbers to convert them back into floats.
