Python 3.6 introduced "DeprecationWarning: invalid escape sequence" warnings. The fix is to use raw literals (br"some bytes" or r"some string") or to escape '\'. $ export PYTHONWARNINGS="d,i::ImportWarning" $ python3.6 -c 'print("\d")' <string>:1: DeprecationWarning: invalid escape sequence \d \d $ python3.6 -c 'print(b"\d")' <string>:1: DeprecationWarning: invalid escape sequence \d b'\\d' $ python3.6 -c 'print(r"\d")' \d $ python3.6 -c 'print(br"\d")' b'\\d' $ python3.6 -c 'print("\\d")' \d $ python3.6 -c 'print(b"\\d")' b'\\d' In Portage: $ python3.6 -c $'import sys\nfor x in sys.argv[1:]:\n with open(x, "rb") as f:\n line = f.readline()\n if line.startswith(b"#!") and b"python" in line:\n f.seek(0, 0)\n compile(f.read(), x, "exec")' $(find * -type f '!' -name '*.py') bin/dispatch-conf:225: DeprecationWarning: invalid escape sequence \s for x in ['^[-+]\s*#', '^[-+]\s*$']: bin/dispatch-conf:225: DeprecationWarning: invalid escape sequence \s for x in ['^[-+]\s*#', '^[-+]\s*$']: $ python3.6 -m compileall * ...
