numpy.core.defchararray.rstrip() function

For each element in a given array numpy.core.defchararray.rstrip() function returns a copy with the trailing characters removed.
Calls str.rstrip element-wise.

Version: 1.15.0

Syntax:

numpy.core.defchararray.rstrip(a, chars=None)

Parameter:

Name	Description	Required / Optional
a: array-like of str or unicode		Required
chars: str or unicode	The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a suffix; rather, all combinations of its values are stripped.	Optional

Return value:

out : ndarray - Output array of str or unicode, depending on input type

Note:

The 'chararray' class exists for backwards compatibility with Numarray, it is not recommended for new development. Starting from numpy 1.4, if one needs arrays of strings, it is recommended to use arrays of 'dtype' 'object_', 'string_' or 'unicode_', and use the free functions in the 'numpy.char' module for fast vectorized string operations.

Some methods will only be available if the corresponding string method is available in your version of Python.

The preferred alias for 'defchararray' is 'numpy.char'.

Example-1: numpy.rstrip() function

import numpy as np 
str1 = 'Python NumPy   '
print("Original string: ",str1)
print("After trailing whitepsace are removed:")
print(np.char.rstrip(str1))

Output:

Original string:  Python NumPy   
After trailing whitepsace are removed:
Python NumPy
