Parsing html using Selenium when class name start with space

Question

I'm trying to parsing text from this html code using Selenium with python:

    <div class="  card card_selected" data-id="3248846777">
        <p>Hello World!</p>
    </div>

I use this code:

my_class = "  card card_selected"
live_deal = browser.find_element_by_class_name(my_class)

I get this error :

selenium.common.exceptions.InvalidSelectorException: Message: Given css selector expression ".  card card_selected" is invalid: InvalidSelectorError: '.  card card_selected' is not a valid selector: ".  card card_selected"

This error happen when the class name start with spaces.

how can I handle this error ?

Please show us the full code.

browser.find_element_by_css_selector('[class|=" "]')

See more details here: https://www.w3schools.com/css/css_attribute_selectors.asp

CSS [attribute|="value"] Selector
The [attribute|="value"] selector is used to select elements with the specified attribute starting with the specified value.

Might be easier to use xpath contains() function

//div[contains(@class,'card_selected')]
