Dear list,
whilst trying to write an array to disk I am coming across the
following. What am I doing wrong? Surely f is a file handle?
(python 3.4.3, numpy 1.9.2)
import numpy as np
a = np.arange(10.)
with open('test.dat', 'w') as f:
np.savetxt(f, a)
It will work if you open with 'wb'. Yes, this seems like a bug; or at
least, the anomaly should be noted in the docstring.
