How can I use open_http in lxml.html.submit_form to alternate opener? I do not know how to fix the last line of code. from lxml.html import parse, submit_form fundurl = 'http://www.aia.com.hk/en/investment-information/fund_search_content_new.jsp…' page = parse(fundurl).getroot() form = page.forms[0] form.fields['date'] = '08/09/2004' form.fields['todate'] = '3m' #### THE FOLLOWING CODE IS INCORRECT #### result = parse(submit_form(form, {'submit':'Search'}, open_http('GET', 'http://www.aia.com.hk/en/investment-information/fund_search_content_new.jsp…', {'date':'08/19/2004','todate':'3m'})))
