numpy.char.rstrip() function

For each element in a given array numpy.char.rstrip() function returns a copy with the trailing characters removed. This method is useful for cleaning up strings before processing them further.

Syntax:

numpy.char.rstrip(a, chars=None)

Parameters:

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:

Output array of str or unicode, depending on input type

Example: Removing trailing whitespace from a string using numpy.char.rstrip()

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

In the above example the np.char.rstrip() function returns a new string with trailing whitespace characters removed from the end of the string. It takes a string as its argument and can also take an optional chars argument that specifies which characters to remove from the end of the string.
