Its possible but does not make sense. In HTML-forms
the element has a name which corresponds to the
variable name you get after form data evaluation
by the server. So in your case you really want:

<form method="post" ... >
  <input type="hidden" name="USER" tal:attributes="value uid" />
  <input type="hidden" name="TEXT" tal:attributes="value pass" />
  <input type="submit" value="for ws0dha" />
</form>

(assumed you nicely pull out uid,pass and so on from your
python script)

btw, if you construct links with parameters, its by far nicer
to do this in your python script, using ZTUtils.make_query()
