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)......
