Selenium Python: Invalid Selector in find_element_by_css_selector

I am building a python3 web bot using selenium-webdriver and don't have too much experience with selenium. I am getting an exception, "selenium.common.exceptions.InvalidSelectorException: Message: invalid selector: An invalid or illegal selector was specified", because of this line of code:

browser.find_element_by_css_selector("button[ng-click='$ctrl.login('gatorlink')']").click();

I'm fairly certain it's related to the single quotes surrounding the string "gatorlink", but I am really not sure. I know the selector is not correct. This is the button I am trying to click.

<button class="md-button md-ink-ripple" type="button" ng-transclude="" ng-click="$ctrl.login('gatorlink')" role="menuitem">
<md-icon class="ng-scope material-icons" role="img" aria-label="exit_to_app">exit_to_app</md-icon>
<span class="ng-scope">Log in with GatorLink</span>
</button>

It's in a drop down and I am able to open the menu but not click this button at the moment.

You have single quotes inside single quotes, it is invalid selector.

You need to escape the single quotes. 

browser.find_element_by_css_selector("button[ng-click='$ctrl.login(\\'gatorlink\\')']").click()

It works now and finding the element.

Try using locator as browser.find_element_by_css_selector(button.md-button md-ink-ripple).click();
