This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


Right now the `_' character seems to have word syntax in python-mode.
M-f and M-b don't stop at an underscore.

I thought the standard in Emacs was that `_' ought to have "symbol
constituent" syntax.

Anyway, I was surprised by the behavior of M-b and M-f in python mode.
I would prefer that the syntax of _ be changed there.
