Pattern

regexPY
(?:0?[1-9]|1[0-2]):[0-5]\d(?::[0-5]\d)?\s?[AaPp][Mm]   (flags: g)

Python (re) code

pyPython
import re

pattern = re.compile(r"(?:0?[1-9]|1[0-2]):[0-5]\d(?::[0-5]\d)?\s?[AaPp][Mm]")
input_text = "9:30 AM"
for m in pattern.finditer(input_text):
    print(m.group(0))

Stdlib `re` module — no third-party dependency. Works on Python 3.6+.

How the pattern works

Hour alternation covers 1–12 (optional leading zero), minute/second classes enforce 00–59, optional whitespace separates the AM/PM suffix. Case-insensitive AM/PM via character classes.
