The “attributeerror: module selenium.webdriver has no attribute opera” error usually occurs if you are trying to use the Opera webdriver with Selenium, yet the Opera webdriver is not found in the Selenium package.
What is module ‘selenium.webdriver’ has no attribute ‘opera’?
The error message “module ‘selenium.webdriver’ has no attribute ‘opera’” usually shows that the version of the Selenium library.
You are using doesn’t support the Opera browser or that the Opera driver is not installed correctly.
To use the Opera browser with Selenium, you should download the Opera driver and add it to your system’s PATH environment variable.
Define the path to the driver executable when making a WebDriver in detail.

How to solve the attributeerror: module ‘selenium.webdriver’ has no attribute ‘opera’?
Time needed: 3 minutes
Here are steps to solve the attributeerror: module ‘selenium.webdriver’ has no attribute ‘opera’.
- Step 1: Install selenium module
The following command is to install the selenium module.
For the specific version:
pip install selenium==4.7
If you run the following command it will install the specific version of selenium in your python environment.
- Step 2: Upgrade selenium module
The following command is to upgrade selenium module.
pip install selenium –upgrade
If you run the following command it will upgrade and change it to the latest version of selenium in your python environment.
- Step 3: Create a new WebDriver for Opera
The following code is to create a new WebDriver for Opera
from selenium.webdriver import Opera, OperaOptions
Set the path to the Opera driver executable
executable_path = ‘/path/to/operadriver’
Set the options for the Opera browser
options = OperaOptions()
options.add_argument(‘–disable-gpu’)
options.add_argument(‘–no-sandbox’)
Create a new instance of the Opera driver
driver = Opera(executable_path=executable_path, options=options)
Make sure to replace /path/to/operadriver with the actual path to the Opera driver that is runnable on your system.
Frequently Asked Questions
What is Python AttributeError and what causes it?
AttributeError is raised when you access an attribute or method that doesn’t exist on the object. Most common cause: calling a method on None (NoneType has no attribute X). Other causes: typo in method name, wrong object type (str when you expected list), or using a feature removed in a newer library version. The error names exactly which type and which missing attribute.
How do I fix ‘NoneType object has no attribute’?
The variable you’re accessing is None, but you expected an object. Trace back to where it was assigned: a function returning None instead of an object (forgot to return), a database query returning no rows (Model.objects.first() returns None when empty), or an API call that failed silently. Safe pattern: if obj is not None: obj.method() OR use the walrus operator: if (obj := get_obj()): obj.method().
How do I check if an attribute exists before accessing it?
Use hasattr(obj, ‘attr_name’) for runtime check, or getattr(obj, ‘attr_name’, default) to get-with-default. For frequent attribute checks, consider type hints + mypy/pyright which catch most AttributeErrors at static-analysis time before runtime.
How do I prevent AttributeError from None values?
Three patterns: (1) Always validate function returns (if result is None: raise). (2) Use type hints with Optional[X] to make None-ability explicit. (3) Use the walrus operator + early return: if (val := get_val()) is None: return default; use val. Defensive coding around None-able returns prevents 90% of AttributeError in production.
Where can I find more AttributeError fixes?
Browse the AttributeError reference hub for 170+ specific fixes (NoneType, pandas, NumPy, sklearn, Selenium). For related errors see TypeError. For Python debugging fundamentals see Python Tutorial hub.
Conclusion
To conclude, with the steps above, you should be able to use the Opera browser with Selenium without encountering the “attributeerror: module ‘selenium.webdriver’ has no attribute ‘opera’” error.
