Regex Tester for Python

Python regex patterns using the re module have specific syntax for named groups, lookaheads, and Unicode matching that can be tricky to get right. While this tester uses the JavaScript engine under the hood, the core regex syntax for character classes, quantifiers, alternation, and most group constructs is shared between the two languages. Use it to rapidly prototype your patterns, then transfer them to your Python code with confidence that the matching logic is sound.
