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)
) is missing after searchbox or after group()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:
# ...
"" to res if it finds nothing. Or alternatively, pass if using except.
res is None, if it is, change it to "".abc(def(. Is that what you want?if condition and traceback. It seems to refer back to the line with re.match even though I do if after regex.None we can do that.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
