How to use webbot from PythonAnywhere ?

Hello there,

I'm pretty new with Python.

I would like to run python script using the webbot librabry : → https://webbot.readthedocs.io/en/latest/

This is a simple script that go to a website, connect to it and refresh every 10min.

Here's some errors from the console :

File "/home/arthurn/.local/lib/python3.7/site-packages/webbot/webbot.py", line 52, in __init__                                                                                                                 
    self.driver = webdriver.Chrome(executable_path=driverpath , chrome_options=options)

There are two problems: 1. You need your account to be upgraded to the new virtualization to run chrome. I can do it for you now. 2. Consoles are ephemeral by design. You need another solution to keep your script live. See https://help.pythonanywhere.com/pages/AlwaysOnTasks/

@streamearn You already have Chrome.

To use it, you'll need to upgrade Selenium for your account -- for example, if you're using Python 3.7, run this in Bash:

pip3.7 install --user --upgrade selenium

...and then you can run Selenium with Chrome using code like this:

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
browser = webdriver.Chrome(options=chrome_options)

try:
    browser.get("https://www.google.com")
    print("Page title was '{}'".format(browser.title))

finally:
    browser.quit()
