What are the available datatypes for ‘dtype’ with NumPy’s loadtxt() an genfromtxt?

by

In addition to np.sctypeDict, there are these variables:

In [141]: np.typecodes
Out[141]: 
{'All': '?bhilqpBHILQPefdgFDGSUVOMm',
 'AllFloat': 'efdgFDG',
 'AllInteger': 'bBhHiIlLqQpP',
 'Character': 'c',
 'Complex': 'FDG',
 'Datetime': 'Mm',
 'Float': 'efdg',
 'Integer': 'bhilqp',
 'UnsignedInteger': 'BHILQP'}

In [143]: np.sctypes
Out[143]: 
{'complex': [numpy.complex64, numpy.complex128, numpy.complex192],
 'float': [numpy.float16, numpy.float32, numpy.float64, numpy.float96],
 'int': [numpy.int8, numpy.int16, numpy.int32, numpy.int32, numpy.int64],
 'others': [bool, object, str, unicode, numpy.void],
 'uint': [numpy.uint8, numpy.uint16, numpy.uint32, numpy.uint32, numpy.uint64]}
