How do I get a value from a class name using selenium in python?

Question

I'm trying to get a value from a class name but the onlything a could get thill now is a [ ] output. so, what I'm supposed to do in the following code?

from selenium import webdriver
import time

options = webdriver.ChromeOptions()
options.add_argument('lang=pt-br')
driver = webdriver.Chrome(
    executable_path=r'./chromedriver.exe', options=options)
driver.get('https://economia.uol.com.br/cotacoes/cambio/')
time.sleep(5)
dolar = driver.find_elements_by_class_name('currency2')
time.sleep(5)
print(dolar)

Do you mean get the text of an element with a currency2 classname? Which value are you trying to get? — Pedro Lobito

You don't need selenium to get that information, try:

import requests

u = "https://api.cotacoes.uol.com/currency/intraday/list/?format=JSON&fields=bidvalue,askvalue,maxbid,minbid,variationbid,variationpercentbid,openbidvalue,date&currency=1"
j = requests.get(u).json()
dolar = j['docs'][0]['bidvalue']
# 5.5916

Demo

Notes:

If you need other info, like daily variation (variationpercentbid) search on json the object:

Change the currency value at the end of the url for a different currency, for example, currency=5, will give you the EUR values.

You can use get_attribute to retrieve value of web element, Also in your code you there is no element with class name currency2.

Please find below example :

<input class="field normal" name="currency2" value="5,59" data-audience-click="{&quot;reference&quot;:&quot;ativar-campo-texto&quot;,&quot;component&quot;:&quot;currency-converter&quot;}" xpath="1">

Code to retrieve value:

driver.get('https://economia.uol.com.br/cotacoes/cambio/')
currency = driver.find_element_by_name('currency2')
print currency.get_attribute("value")

Output::

5,59
