[Numpy-discussion] Astype and strings

Hi Everyone, Is Numpy supposed to behave this like this when converting an array of numbers to an array of strings with astype? print(arange(20).astype(np.str)) ['0' '1' '2' '3' '4' '5' '6' '7' '8' '9' '1' '1' '1' '1' '1' '1' '1' '1' '1' '1'] When I do the following it works fine, print(arange(20).astype('|S2')) ['0' '1' '2' '3' '4' '5' '6' '7' '8' '9' '10' '11' '12' '13' '14' '15' '16' '17' '18' '19'] I would have thought that astype would be more intelligent with strings rather than just resorting to the first character for each element. Is this a bug or or is it how astype works? Thanks, Eli
