Use NETRC environment variable

[berthin]

Feature or enhancement

Proposal:

Hi,

I'd like to add support to the NETRC environment variable as documented in GNU inetuils v2.6 (https://www.gnu.org/software/inetutils/manual/html_node/The-_002enetrc-file.html). Other tools and libraries are already supporting that envvar and I think it would be nice to aligned as well in that regard.

Supporting the envvar should be as simple as changing:

cpython/Lib/netrc.py

Line 70 in 7c43615

file = os.path.join(os.path.expanduser("~"), ".netrc")

with

file = os.environ.get("NETRC", None) or os.path.join(os.path.expanduser("~"), ".netrc")

Best regards,
Berthin

FTR, it's supported in (pip) pypa/pip#11023 and requests (psf/requests#5643) as well as httpx (https://www.python-httpx.org/advanced/authentication/#netrc-authentication).

I think it's a legitimate addition, though any PR doing it needs tests & docs.
