Numpy's np.char.rstrip(~) method takes as input an array of strings, and removes specified characters on the right side of each string.

Note that the original array is left intact, and a brand new copy of the array is returned.

Parameters

1. a | array-like

The input array of strings.

2. chars | str or unicode | optional

The characters located on the right side of string that you want removed. Note that if chars="ab", for instance, the characters that will be removed will be the combinations of the parameter value, that is, "ab" and "ba".

Return value

A new Numpy array with the specified characters residing at the right of the input strings removed.

Examples

Removing right whitespaces

np.char.rstrip(["Hello ", "World "])
array(['Hello', 'World'], dtype='<U8')

Removing right custom characters

np.char.rstrip(["zba", "zab"], "ab")
array(['z', 'z'], dtype='<U3')

Notice how both "ba" and "ab" were removed - it's the combinations of the specified characters that are removed.
