numpy.core.defchararray.isnumeric(arr) function returns true for each element if there are only numeric characters and there is at least one character.It returns false otherwise.
Parameters:
arr : array_like of str or unicode.Returns : [ndarray] Output array of bools.
Code #1 :
# Python program explaining # numpy.char.isnumeric() method import numpy as geek # input array contains only numeric character in_arr = geek.array([ '1000', '2000'] ) print ("Input array : ", in_arr) out_arr = geek.char.isnumeric(in_arr) print ("Output array: ", out_arr) |
Output:
Input array : ['1000' '2000'] Output array: [ True True]
Code #2 :
# Python program explaining # numpy.char.isnumeric() method import numpy as geek # input array in_arr = geek.array([ 'python3.5', 'a1000', '1234 ab'] ) print ("Input array : ", in_arr) out_arr = geek.char.isnumeric(in_arr) print ("Output array: ", out_arr) |
Output:
Input array : ['python3.5' 'a1000' '1234 ab'] Output array: [False False False]
