You can define a list of valid keys to look for:
keys = ['one', 'two', 'three', 'four', 'five']
for key in keys:
if not key in request.POST:
continue
.. do stuff ..
Or you can delete the keys you don't want before looping:
for key in ['x', 'y', 'submit']:
del request.POST[key]
for key, value in request.POST.iteritems():
... do stuff ...
