Click on element in dropdown with Selenium and Python

Question

With Selenium and Chrome webdriver on MacOS need to click dropdown element. But always have an error that can't find. Have this html code on a page where it located:

<select id="periodoExtrato" name="periodoExtrato" class="EXTtexto" onchange="enviarExtrato(document.formperiodo.periodoExtrato[document.formperiodo.periodoExtrato.selectedIndex].value);">
<!--<option value="01" >&Uacute;ltimo dia</option>-->
<option value="03" selected="true">Últimos 3 dias</option>
<option value="05">Últimos 5 dias</option>
<option value="07">Últimos 7 dias</option>
<option value="15">Últimos 15 dias</option>
<option value="30">Últimos 30 dias</option>
<option value="X">Data específica (até 60 dias)</option>
<option value="D">Mês completo (desde 2002)</option>
</select>

I need to choose Últimos 15 dias, so i have this code:

self.driver.find_element_by_xpath('//[@id="periodoExtrato"]/option[4]').click()

But have an error:

I would suggest not using xpath here. Try, instead, something like this:

 select = Select(self.driver.find_element_by_id('periodoExtrato'))
 option_indexes = range(1, len(select.options))
 for index in option_indexes:
    select.select_by_index(index)
    ......

Now I understand, a problem is in that element goes after </head> at <frameset>, so it can't find it. Do you know how to locate there?

Problem solved with self.driver.switch_to_frame(name).

A problem is that element goes after </head> in <frameset>, so selenium can't find it. After adding this string problem solved.

browser.switch_to_frame('name')

And after that

self.driver.find_element_by_xpath('//[@id="periodoExtrato"]/option[4]').click()
