Java: Use them for searching, replacing and validating that text meets certain formats.
PHP supports regular expressions through the use of the PCRE (Perl Compatible Regular Expressions) library which is enabled in almost all PHP installations.
Python: In this course, we'll explore the re module that Python provides and learn to write regular expressions for many different situations.

Excellent work learning a powerful new tool.
Now that you know about regular expressions,
I bet you'll use them everywhere.

For example, most code editors let you use regular expressions to search and

Combine that with the ability to replace what you find and
you can build even more powerful solutions.
Reformat user input or entire files.
Rename multiple files at once, or set up advanced redirects in an HT access file.
You'll find yourself reaching for regular expressions more and
more as you use them in your daily practice.
