How Can Regular Expressions Eliminate Extraneous Spaces in Strings?

Eliminating Extraneous Spaces with Regular Expressions

Often, strings contain unnecessary spaces that can clutter the text and disrupt readability. To address this issue, consider employing the power of regular expressions.

Regex Solution:

Python's re module provides a concise and elegant way to manipulate strings using regular expressions. To remove multiple spaces, you can use the following command:

import re
result = re.sub(' +', ' ', 'The   fox jumped   over    the log.')

This command utilizes the re.sub() function, which replaces all occurrences of a specified pattern with a replacement string. In this case, the pattern ' ' matches one or more consecutive spaces, and it's replaced with a single space, as specified by ' '.

Example:

Consider the string:

The   fox jumped   over    the log.

After applying the regex operation, the resulting string will be:

The fox jumped over the log.

All the unnecessary spaces have been removed, leaving behind a clean and readable text.
