In this tutorial, we explored various examples of how to use regular expressions in Python to extract signed and unsigned integers, floating-point numbers, and a mix of both. By modifying the regex pattern slightly, you can adjust it to match exactly what you need in your specific application.
r"[+-]?\d+"
: Matches signed or unsigned integers.r"[+-]?\d+(\.\d+)?"
: Matches signed or unsigned floating-point numbers and integers.r"\+?\d+(\.\d+)?"
: Matches only positive numbers (with or without a +
).
