The Lib/smtpd.py and Tools/i18n/msgfmt.py scripts write their version strings to stderr. It should be changed to stdout for consistency with most common practice. See also bpo-18338 and bpo-18920.

Now The Lib/smtpd.py and Tools/i18n/msgfmt.py scripts write their version strings to stdout, and not to sderr.

Applying the patch the stdout can be redirect
/python.exe Lib/smtpd.py --version >> /dev/null

Without the patch:
/python.exe Lib/smtpd.py --version >> /dev/null
Python SMTP proxy version 0.3
