How to use the rstrip string method in Julia

Programming Bytes

Overview

The rstrip method in Julia removes the specified characters from the trailing end (right side) of a given string.

Syntax

rstrip(sourcestr::AbstractString, charsToBeRemoved)

Arguments

This method takes two arguments:

  1. sourcestr: This is the string from which the trailing characters are to be removed.
  2. chars: These are the characters that are to be removed.

Return value

This method returns a new string by removing the specified trailing characters from the given string.

Code example

The code below demonstrates how we can use the rstrip method:

# Removing the character 'r' at the end
println(rstrip("winner", ['r']))

# Removing the characters 'r', 'n', 'e', at the end
println(rstrip("winner", ['r', 'n', 'e']))

# Removing the character 'g' at the end
println(rstrip("winner", ['g']))
Using the rstrip method

Code explanation

Line 2: We use the rstrip method with the string, with:

  • winner as the source string
  • ['r'] as the character to be removed from the end of the string.

The rstrip method loops the source string from the end and removes the character that matches 'r'. The loop is stopped when a character of the source string is not present in the removable characters. In our case, we get winnne as a result.

Line 4: We use the rstrip method with the string, with:

  • winner as the source string
  • ['r', 'n', 'e'] as the characters to be removed from the end of the string.

The rstrip returns wi as a result.

Line 6: We use the rstrip method with the string, with:

  • winner as the source string
  • ['g'] as the character to be removed from the end of the string.

The rstrip returns winner as a result. The character 'g' is not present in the source string.
