Pattern

regexPY
^\.[^.\s/\\][^/\\]*$

Python (re) code

pyPython
import re

pattern = re.compile(r"^\.[^.\s/\\][^/\\]*$")
input_text = ".gitignore"
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

`^\.` requires leading dot. `[^.\s/\\]` requires the next character to not be another dot, whitespace, or slash. `[^/\\]*$` allows any additional non-slash characters.
