I use Regex to retrieve certain content from a search box on a webpage with selenium.webDriver.
searchbox = driver.find_element_by_class_name("searchbox")
searchbox_result = re.match(r"^.*(?=(\())", searchbox).group()
The code works as long as the search box returns results that match the Regex. But if the search box replies with the string "No results" I get error:
AttributeError: 'NoneType' object has no attribute 'group'
How can I make the script handle the "No results" situation?

I managed to figure out this solution: omit group() for the situation where the searchbox reply is "No results" and thus doesn't match the Regex.
try:
searchbox_result = re.match("^.*(?=(\())", searchbox).group()
except AttributeError:
searchbox_result = re.match("^.*(?=(\())", searchbox)
When you do
re.match("^.*(?=(\())", search_result.text)
then if no match was found, None will be returned:
Return
Noneif the string does not match the pattern; note that this is different from a zero-length match.
You should check that you got a result before you apply group on it:
res = re.match("^.*(?=(\())", search_result.text)
if res:
# ...
This error occurs due to your regular expression doesn't match your targeted value. Make sure whether you use the right form of a regular expression or use a try-catch block to prevent that error.
try:
pattern = r"^.*(?=(\())"
searchbox_result = re.match(pattern, searchbox).group()
except AttributeError:
print("can't make a group")
Thank you
