Converting empty strings to 0 using Numpy

Question

I have a numpy array where each element looks something like this:

[\'3\' \'1\' \'35\' \'0\' \'0\' \'8.05\' \'2\']
[\'3\' \'1\' \'\' \'0\' \'0\' \'8.4583\' \         


        

Answer 1

Just do this first:

s = np.array(['1', '0', ''])
s[s==''] = '0'

s.astype(float)
#array([ 1.,  0.,  0.])
