While working with Python, you might face the AttributeError: NoneType object has no attribute group. Why does this happen, and how can you solve it? You will find the answers in this post.
What Cause AttributeError: NoneType object has no attribute group
The AttributeError: NoneType object has no attribute group will occur when the Python interpreter is unable to access or retrieve group attribute from the class.
It might not be specified inside the class or it might be privately expressed, in which case external objects can’t access it. It is helpful to consider that the interpreter is attempting to access characteristics from any class that are either not present in the class or to which it is not permitted.
Below is an example of the error in action.
searchbox = driver.find_element_by_class_name(“searchbox”)
searchbox_result = re.match(r”^.*(?=(\())”, searchbox).group()
Output:
AttributeError: ‘NoneType’ object has no attribute ‘group’
In the example above, the match method didn’t match any objects, thus it returned nothing, which causes the error to increase. As a result, it is an object’s NoneType.
The indicated error is now thrown when we attempt to group objects from the empty object, meaning you may group multiple objects. In this case, it would be ideal to have a few empty objects.
Fix AttributeError: NoneType object has no attribute group Using try-except Block
You may try binding the error in the try-except block to fix the problem. As a result, you may group the objects when the function match returns a list of the grouping objects without making a mistake.
Keep in mind that you don’t need to group the objects if the method match returns the value null.
Check out this example to see how the try-except block is put into action.
try:
searchbox_result = re.match(“^.*(?=(\())”, searchbox).group()
except AttributeError:
searchbox_result = re.match(“^.*(?=(\())”, searchbox)
Fix AttributeError: NoneType object has no attribute group Using Statement If
Another method to solve the AttributeError: NoneType object has no attribute group by utilizing the statement if. You may add this statement and evaluate it against None. You have the option to pass or return it when the condition is met.
Notice that you will receive the value None in case the string doesn’t match the pattern. Plus, it would be best to check to ensure you received a result before applying group on the code.
Here is an example for you to use as a reference.
searchbox = driver.find_element_by_class_name(“searchbox”)
searchbox_result = re.match(r“^.*(?=(\())”, searchbox).group()
if searchbox_result is None:
return None # or pass
else:
do...something
