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

If your array is t:

t[t=='']='0'

and then convert it.

Explanation:

t=='' creates a boolean array with the same shape as t that has a True value where the corresponding t value is an empty space. This boolean array is then used to assign '0' only to the appropriate indices in the original t.
