Is there a way to convert an array to string elements in numpy,
without knowing the string length?
>>> arr2 = np.arange(8, 13)
>>> arr2.astype(str) # bad
array(['8', '9', '1', '1', '1'],
dtype='|S1')
>>> arr2.astype('S2')
array(['8', '9', '10', '11', '12'],
dtype='|S2')
>>> map(str, arr2)
['8', '9', '10', '11', '12']
>>> arr3 = np.round(np.random.rand(5), 2)
>>> arr3
array([ 0.51, 0.86, 0.15, 0.68, 0.59])
>>> arr3.astype(str) # bad
array(['0', '0', '0', '0', '0'],
dtype='|S1')
>>> arr3.astype('S4')
array(['0.51', '0.86', '0.15', '0.68', '0.59'],
dtype='|S4')
>>> map(str, arr3)
['0.51', '0.86', '0.15', '0.68', '0.59']
>>> np.__version__
'1.5.1'
(from an issue in statsmodels)
Thanks,
Josef
