如何使用python在本网站中提交动态表单？

Question

我是一个网络垃圾的新手，在这个网站上有一个多星期的麻烦

我想要的是填写表格与国家和城市的信息，然后该网站将返回我一个表。我想要这些表的信息

我不知道在“浏览器[”？？“]=”？？“中输入什么来提交表单。我试过“option”、“estadoSAGIUFMU”、“form”、“estadoSAGIUFMU”，但都没有成功

以下是可以提交的州数据：

<table>
    <tr>
        <td>
            <select name='uf_ibge' style='width: 240px' id='estadoSAGIUFMU' onchange="document.getElementById('nome_estadoSAGIUFMU').value=this.options[this.selectedIndex].text;ajaxSAGIUF('selector_municipiosSAGIUF','p_ibge='+this.value);document.getElementById('selector_municipiosSAGIUF').innerHTML = '';">
                set names 'utf8';select uf, n_uf as estado, id_uf as ibge from mapas.shp_uf order by uf
                <option value=''>Selecione um estado</option>
                <option value='12'>AC - Acre</option>
                <option value='27'>AL - Alagoas</option>
                <option value='13'>AM - Amazonas</option>
                <option value='16'>AP - Amapá</option>
                <option value='29'>BA - Bahia</option>
                <option value='23'>CE - Ceará</option>
                <option value='53'>DF - Distrito Federal</option>
                <option value='32'>ES - Espírito Santo</option>
                <option value='52'>GO - Goiás</option>
                <option value='21'>MA - Maranhão</option>
                <option value='31'>MG - Minas Gerais</option>
                <option value='50'>MS - Mato Grosso do Sul</option>
                <option value='51'>MT - Mato Grosso</option>
                <option value='15'>PA - Pará</option>
                <option value='25'>PB - Paraíba</option>
                <option value='26'>PE - Pernambuco</option>
                <option value='22'>PI - Piauí</option>
                <option value='41'>PR - Paraná</option>
                <option value='33'>RJ - Rio de Janeiro</option>
                <option value='24'>RN - Rio Grande do Norte</option>
                <option value='11'>RO - Rondônia</option>
                <option value='14'>RR - Roraima</option>
                <option value='43'>RS - Rio Grande do Sul</option>
                <option value='42'>SC - Santa Catarina</option>
                <option value='28'>SE - Sergipe</option>
                <option value='35'>SP - São Paulo</option>
                <option value='17'>TO - Tocantins</option>
            </select>
            <input name='nome_estado' id='nome_estadoSAGIUFMU' type='hidden' value=''>
        </td>
        <td>
            <div id='selector_municipiosSAGIUF'>
            </div>
        </td>
    </tr>
</table>

这是我到现在为止写的代码

from mechanize import Browser
import lxml.html as lh

browser = Browser()
browser.open('http://aplicacoes.mds.gov.br/sagirmps/estrutura_fisica/preenchimento_municipio_cras_new1.php')

browser.select_form(nr=0)
browser['????'] = '????'

我也试过：

import requests
url = 'http://aplicacoes.mds.gov.br/sagirmps/estrutura_fisica/preenchimento_municipio_cras_new1.php'
r = requests.post(url, data = {'Selecione um estado':'SP - São Paulo', 'Selecione um município': 'Bauru'})

r.text

但是当我使用r.text时，它显然会返回整个html代码
