Hello,
I am trying to find an efficient way to concatenate the elements of
two same-length numpy str arrays. For example if I define the
following arrays:
import numpy as np
arr1 = np.array(['a','b','c'])
arr2 = np.array(['d','e','f'])
I would like to produce a third array that would contain
['ad','be','cf']. Is there an efficient way to do this? I could do
this element by element, but I need a faster method, as I need to do
this on arrays with several million elements.
Thanks for any help,
Thomas
