How to match at the end of string in python using Regular Expression?

PythonServer Side ProgrammingProgramming

A regular expression in Python is a set of characters that allows you to use a search pattern to find a string or a group of strings. RegEx is another term for regular expressions.

Regular expressions are worked within Python using the re package.

To match with the end of the string in python by using a regular expression, we use ^/w+$ regular expression.

Here,

  • $ implies the start with.

  • /w returns a match where the string contains any word characters (a z, A Z, 0 9, and underscore character).

  • + indicates one or more occurrences of a character.

Using re.search() method

In the following example code, we match the word skills which is present at the end of the string ‘tutorialspoint is a great platform to enhance your skills’.

We begin by importing the regular expression module.

import re

Then, we have used the search() function which is imported from the re module. This re.search() function in Python searches the string for a match and returns a match object if there is any match. The group() method is used to return the part of the string that is matched.

Example

import re
s = 'tutorialspoint is a great platform to enhance your skills'
result = re.search(r'\w+$', s)
print(result.group())

Output

The following output is obtained on executing the above program.

skills

Using re.findall() method

The method findall(pattern, string) in python locates every occurrence of the pattern within the string. The dollar-sign ($) guarantees that you only match the word Python at the end of the string when you use the pattern "\w+$".

Example

import re
text = 'tutorialspoint is a great platform to enhance your skills'
result = re.findall(r'\w+$', text)
print(result)

Output

Following is an output of the above code
