How to insert text into an input tag using selenium and python

Question

I'm able to find the element by class name that this resides in but I'm not sure how to select it itself and send text to it.

Current Code:

editor = browser.find_element_by_class_name('editor')
editor.send_keys('text')

Element I'm trying to select:

<input type="text" tabindex="103" placeholder="" style="width: 444px;">

Error:

File "C:\Python35\lib\site-packages\selenium\webdriver\remote\webelement.py", line 347, in send_keys
    self._execute(Command.SEND_KEYS_TO_ELEMENT, {'value': keys_to_typing(value)})
  File "C:\Python35\lib\site-packages\selenium\webdriver\remote\webelement.py", line 494, in _execute
    return self._parent.execute(command, params)

Answer 1

Element that you try to select doesn't have class name. Try

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

editor = WebDriverWait(browser, 10).until(EC.visibility_of_element_located((By.XPATH, '//input[@type="text"][@tabindex="103"]')))
editor.send_keys('text')

Answer 2

在editor.send_keys('text') editor.click()之前尝试使用editor.click()并查看它是否有效。
