python - Check variable if it is in a list -

-

i new python, , wondering if there succinct way of testing value see if 1 of values in list, similar sql clause. sorry if basic question.

msupdate.updateclassificationtitle in (         'critical updates',         'feature packs',         'security updates',         'tools',         'update rollups',         'updates',         )

i.e, want write:

if msupdate.updateclassificationtitle in (         'critical updates',         'feature packs',         'security updates',         'tools',         'update rollups',         'updates'         ):       then_do_something()

seems succinct enough, if you're using more once should name tuple:

titles = ('critical updates',     'feature packs',     'security updates',     'tools',     'update rollups',     'updates')  if msupdate.updateclassificationtitle in titles:       do_something_with_update(msupdate)

tuples use parenthesis. if want list change square brackets. or use set, has faster lookups.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
