Converting string to numpy array
Given a string abcxyz, I want it to return a numpy array like:
array(["a", "b", "c", "x", "y", "z"]).
I have tried fromstring
Bingrid = np.fromstring(elements, dtype=str)
but it returns
ValueError: Zero-valued itemsize.
Just in case; if you do not want to convert into a list:
np.fromiter('abcxyz',(str,16))
#array(['a', 'b', 'c', 'x', 'y', 'z'], dtype='<U16')
Use list().
import numpy as np
s = "abcxyz"
print(np.array(list(s)))
Output:
['a' 'b' 'c' 'x' 'y' 'z']
How about np.array(list("abcxyz")) ? No need for any special methods.
Convert to a list, then to an array:
import numpy as np
Bingrid = np.array(list("abcxyz"))
This one works for me:
import numpy as np
mystr = "100110"
res = np.array(list(mystr))
print(res)

numpy.array(list("abcxyz"))fromstring()is for parsing a delimited list, like a CSV.
