Update module.py documentation. (#19347)
Summary:
Added the ">>>" python interpreter sign(three greater than symbols), so that the edited lines will appear as code, not comments/output, in the documentation. Normally, the interpreter would display "..." when expecting a block, but I'm not sure how this would work on the pytorch docs website. It seems that in other code examples the ">>>" sign is used as well, therefore I used with too.
