Опубликовано: 26 Марта, 2022

numpy.core.defchararray.strip(arr, chars=None) is another function for doing string operations in numpy. It returns a copy with the leading and trailing characters removed for each element in arr.

Parameters:
arr : array_like of str or unicode.
char : [str or unicode, optional] the set of characters to be removed. If omitted or None, it removes whitespace. The chars argument is not a prefix or suffix; it is all combinations of its values which we want to strip.

Returns : [ndarray] Output array of str or unicode, depending on input type.

Code #1 :

# Python program explaining
# numpy.char.strip() method 
  
import numpy as geek
  
# input arrays  
in_arr = geek.array(["Sun", "  Moon  ", "Star"])
print ("Input array : ", in_arr) 
  
out_arr = geek.char.strip(in_arr)
  
# whitespace removed from arr[1] 
# as we have set chars = None
print ("Output array: ", out_arr) 
Output:

Input array :  ["Sun" " Moon " "Star"]
Output array:  ["Sun" "Moon" "Star"]
