Python String rstrip() Method – Remove Trailing Characters

Let’s look at string rstrip() method – remove trailing characters

  1. Notice

    rstrip() removes trailing whitespace by default. Its chars argument is a set of characters, not a complete suffix.

  2. Try

    Follow the example, change its sample, and compare what happens.

  3. Check

    Explain the result and test your understanding.

Watch how it works

Focus on how the names, objects, and calculations change. We’ll inspect the printed output in the next section.

Python String rstrip() Method

The rstrip() method in Python is used to remove trailing characters (characters at the end) from a string. By default, it removes any whitespace characters (like space, tab, or newline) from the right side of the string.

Syntax

string.rstrip([chars])

Parameters:

  • chars (optional) – A string specifying the set of characters to be removed. If omitted, whitespace is removed.

Returns:

  • A copy of the string with trailing characters removed.

Example 1: Remove Trailing Whitespace

text = "Hello World   "
result = text.rstrip()
print(result)
Hello World

Example 2: Remove Specific Trailing Characters

text = "hello!!!"
result = text.rstrip("!")
print(result)
hello

Use Case: Cleaning Up User Input

You can use rstrip() to clean up strings where extra characters are present at the end — for example, when reading data from a file:

line = "data123***\n"
cleaned = line.rstrip("*\n")
print(cleaned)
data123

Difference Between rstrip(), lstrip(), and strip()

  • rstrip() – removes from the right end
  • lstrip() – removes from the left end
  • strip() – removes from both ends

Common Mistake

  • Note: rstrip() removes characters as a set, not a sequence. For example, rstrip("!d") removes any combination of ! or d until it finds a character not in the set.

Interview Tip

Use rstrip() when working with file lines or logs where trailing newlines or specific characters need to be stripped safely.

Summary

  • rstrip() removes characters from the right side.
  • By default, it removes whitespace.
  • You can specify a custom set of characters to remove.
  • Returns a new string, doesn't change the original.

Practice Problem

Write a program to remove all trailing dollar signs '$' from a user-input string.

user_input = input("Enter a string with trailing $: ")
print("Cleaned:", user_input.rstrip("$"))

What to remember

Connect what you noticed in the example with the idea below.

Remember

rstrip() removes trailing whitespace by default. Its chars argument is a set of characters, not a complete suffix.

Watch out for this idea

rstrip("ab") removes only the literal suffix ab.

This is the misconception to avoid.
