Below is a snippet of code from my python script that is reading an excel file and assigning cells in a row to a variable that is then used to be typed into a field in the browser. it works great ... for the most part. what i would like to do is setup some sort of loop after the browser loads the page to do the following:
find the element by some ID. if this fails, wait 5 seconds then try again. if it succeeds carry on with the rest of the script. now go easy on me, this is my first real attempt. i have tried to nest try/except statements but that got really messy fast.
from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
import time
import xlrd
workbook = xlrd.open_workbook("my_excel_file.xlsx")
worksheet = workbook.sheet_by_name('Sheet1')
x = 0
for current_row in range(worksheet.nrows):
try:
cmt = worksheet.row(current_row)[2].value
browser = webdriver.Firefox() # Get local session of firefox
browser.get("http://www.somewebsite.com") # Load page
time.sleep(5)
#this timer is the issue, if the field takes 6 seconds to be ready, script fails
comment = browser.find_element_by_id("slow_comment_box") # Find the comment box
comment.send_keys(str(cmt) + Keys.RETURN)
x += 1
except:
print ("Error on " + str(x))
quit ()
is there a way to set this to behave the way i stated above? i know selenium waits for the page to load but the text box is not a normal one and appears to have its own loading, spinning wheel.
summary and solution the answer is below. my dumb stuff had some syntax errors. this page was extremely useful as well.
You want to use WebDriverWait
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
element = WebDriverWait(driver, 60).until(EC.visibility_of_element_located((By.Id, 'id')))
