What are the differences between wildcards and regex in Python?

Wildcards are simpler patterns used for matching filenames, while regex is more powerful for complex string matching.

Can you give me an example of using wildcards in Python?

Sure! You can use the fnmatch module to match filenames with wildcards like *.txt to find all text files.

And how would I use regex for the same purpose?

You can use the re module with a pattern like r'.*\.txt$' to match all text files in a more flexible way.

Which one should I use for data validation?

For data validation, regex is usually preferred due to its ability to define complex patterns.
