无法让Webelement在Python 2.7中打印

Question

So this is the code that I am running:

from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium import webdriver
from selenium.webdriver.support import ui
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys
current_price = []
def page_is_loaded(driver):
    return driver.find_element_by_tag_name("body") != None
driver = webdriver.Firefox()
driver.get("https://marketsworld.com/")
wait = WebDriverWait(driver, 10)
wait.until(page_is_loaded)
email_field = driver.find_element_by_id("user_login_email")
email_field.send_keys("myusername")
password_field = driver.find_element_by_id("user_login_password")
password_field.send_keys("mypass")
password_field.send_keys(Keys.RETURN)
element = driver.find_element_by_class_name("market_value")
instance = element.text
print instance

When I try to print instance , the output I get is

/usr/bin/python2.7 /home/phuhzy/PycharmProjects/pychar_test/test2.py

(I don't get any output here. Only a blank line.)

Process finished with exit code 0

Not sure why I am getting a blank line as the output. If I print it out as, print type(instance) , I get unicode back as the type.

Answer 1

I assume the element.text is empty or None and there is nothing to print.

Without knowing the actual data it is impossible to say.

You can test it by

if not instance:
    print "No data"
