In this case, the specified regex is #(\w+)#. The matching strings are '#foo#', '#bar#', and '#baz#'. But the hash (#) characters don’t appear in the return list because they’re outside the grouping parentheses.If <regex> contains more than one capturing group, then re....
However, as we’ll see in our examples, it's important to acknowledge the inherent limitations of these methods: they are not capable of removing characters from the middle of strings or handling more complex pattern-based removals. For such advanced needs,regular expressions (regex)provide a mo...
