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 :
import numpy as geek
in_arr = geek.array([ 'Sun' , ' Moon ' , 'Star' ])
print ( "Input array : " , in_arr)
out_arr = geek.char.strip(in_arr)
print ( "Output array: " , out_arr)
|
Output:
Input array : ['Sun' ' Moon ' 'Star']
Output array: ['Sun' 'Moon' 'Star']
Code #2 :
import numpy as geek
in_arr = geek.array([ 'Sun' , ' Moon ' , 'Star' ])
print ( "Input array : " , in_arr)
out_arr = geek.char.strip(in_arr, chars = 'Sun' )
print ( "Output array: " , out_arr)
|
Output:
Input array : ['Sun' ' Moon ' 'Star']
Output array: ['' ' Moon ' 'tar']
Code #3 :
import numpy as geek
in_arr = geek.array([ 'Geeks' , 'For' , 'Geeks' ] )
print ( "Input array : " , in_arr)
out_arr = geek.char.strip(in_arr, chars = 'G' )
print ( "Output array: " , out_arr)
|
Output:
Input array : ['Geeks' 'For' 'Geeks']
Output array: ['eeks' 'For' 'eeks']
