Regex search for string

[DBS]

Hello,

I'm trying to formulate a regex search to see if this exact string, ''op_single_selector" exists in this line of text:

-> [!div class="op_single_selector"]

This is what I have now that's not working:

selector_string = False
single_selector_regex_search_string = re.compile(r"[\+-]>\s\[op_single_selector\]")
if single_selector_regex_search_string.search(file_information.patch):
    selector_string = True
