Python try except function with time-out limit-CodePudding

I am searching within a PowerBI dashboard with Selenium a certain pop-up window to insert a search term. I can only do this in stable way by creating a function which looks for all input fields and then try to send the term within a try-except-clause which takes very long.

Hence I am wondering if it is possible to insert a command how long to wait till an exception occurs.

Here is my code

fields_searchheader = browser.find_elements_by_css_selector(".searchHeader.show > .searchInput")
for i in fields_searchheader:
    try:
        i.clear()
        i.send_keys("hallo)
        # wait function till exception if no feedback
    except Exception:
        print("d")

Would be great to get an idea. Thanks!

I would recommend to you to use - Expected Conditions

And also to make it stable - tune it by using polling.

Something like this?

it will wait up to..not for the number of seconds..
