Pandas Series str.rstrip(~) method removes the combination of the specified characters that appear from the right of each string in the Series.

Note that a new Series is returned, and the original is kept intact.

Parameters

1. to_strip | str or None | optional

The combination of the characters of to_strip that appears at the back of each string will be removed. For instance, if to_strip="ab", then Aab and Aba will both become A.

By default, trailing whitespaces (including newlines and tabs) will be removed.

Return value

A new Series or Index.

Examples

Basic usage

By default, rstrip(~) removes trailing whitespaces (including newlines and tabs):

s = pd.Series([" ","a a","\na","a\t"])
s_stripped = s.str.rstrip()
s_stripped
0
1 a a
2 a
3 a
dtype: object

To confirm that the whitespaces have indeed been stripped, we print the length of each string:

s_stripped.str.len()
0 0
1 3
2 1
3 1
dtype: int64

Specifying to_strip

To remove a combination of the characters "ab" at the back:

s = pd.Series(["Aab","Aba"])
s.str.rstrip("ab")
0 A
1 A
dtype: object
