Git Commit SHA in PY

Match Git commit hashes, both short (7 chars) and full (40 chars) forms.

Pattern

\b[0-9a-f]{7,40}\b   (flags: g)

Python (re) code

import re

pattern = re.compile(r"\b[0-9a-f]{7,40}\b")
input_text = "commit 75d2cb0"
for m in pattern.finditer(input_text):
    print(m.group(0))

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