Pattern

regexPY
\b[0-9a-fA-F]{24}\b   (flags: g)

Python (re) code

pyPython
import re

pattern = re.compile(r"\b[0-9a-fA-F]{24}\b")
input_text = "507f1f77bcf86cd799439011"
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

Word-bounded exactly 24 hex digits. Case-insensitive character class covers both upper and lower case forms produced by different drivers.
