Fixed syntax error in doctest (#15646)
Summary:
I fixed a very small extra parenthesis in a doctest.
I'm also going to use this issue as a place to propose the eventual inclusion of xdoctest (a pip installable library I wrote) in pytorch's test suite. I think there are a lot of problems with Python's built in doctest module, and I've built xdoctest to fix them. I would love for my project to get some exposure and its addition to PyTorch may benefit both projects. Please see the readme for more details on what xdoctest brings to the table over the builtin doctest module: https://github.com/Erotemic/xdoctest
I came across this small syntax error when working on ensuring xdoctest was compatible with pytorch. It isn't 100% there yet, but I'm working on it. My goal is to ensure that xdoctest is 100% compatible with all of torch's doctest out-of-the-box before writing up the PR. I'm also airing the idea out-loud before I commit too much time into this (or get my hopes up), so I'm attaching this little blurb to a no-brainer-merge PR to (1) demonstrate a little bit of value (because xdoctest flagged this syntax error) and (2) see how its received.
