Having difficulties fixing Attributeerror: module ‘whois’ has no attribute ‘whois’ in your python code? Don’t worry, this article is for you.
In this article, we will discuss the possible causes of this Attributeerror, and provide solutions to resolve the error.
But before anything else let’s discuss first what python whois means.
What is python whois?
In Python, the whois module is a third-party library that allows you to interact with WHOIS servers and retrieve this information programmatically.
WHOIS is a protocol used to retrieve information about domain names, IP addresses, and other network-related information
To use the whois module in your Python code, you can install it using pip by running the command:
pip install python-whoisNow let’s discuss what Attributeerror: module ‘whois’ has no attribute ‘whois’ means.
What is Attributeerror: module ‘whois’ has no attribute ‘whois’?
The “AttributeError: module ‘whois’ has no attribute ‘whois‘” is an error message indicating that you are trying to access an attribute named “whois” in the “whois” module, but the attribute does not exist in the module.
Here’s an example code that could raise an error with the message “module ‘whois’ has no attribute ‘whois’”:
import whois
domain = 'example.com'
w = whois.whois(domain)In this example code, it tries to use the whois module to retrieve information about a domain name, but if the whois module doesn’t have an attribute called whois, an error will be raised with the message :
AttributeError: module 'whois' has no attribute 'whois'Next, Let us know how this Attributeerror occurs.
How does this Attributeerror: module ‘whois’ has no attribute ‘whois’ Occurs?
The error “AttributeError: module ‘whois’ has no attribute ‘whois’” occurs when Python code tries to access an attribute or method in the whois module that doesn’t exist.
This can happen for a variety of reasons, such as:
- Outdated or missing whois module:
If the whois module is not installed or an outdated version is installed, the whois.whois() method may not be available.
- Typo or incorrect usage:
If there is a typo in the code or the whois.whois() method is not used correctly, an error may occur.
For example:
import whois
# Incorrect usage of whois.whois() method
w = whois(domain='example.com')
# Typo in the module name
w = whios.whois('example.com')- Compatibility issues:
If there is a compatibility issue between the whois module and other dependencies or the Python version, the error may occur.
For example, if the whois module is not compatible with Python 3.10 yet, you may encounter an Attributeerror if you try to use it with that version.
Now lets Fix this Attributeerror.
Attributeerror: module ‘whois’ has no attribute ‘whois’ – Solution
Here are the different ways to fix this Attributeerror: module ‘whois’ has no attribute ‘whois’:
- Update or reinstall the whois module:
Make sure you have the latest version of the whois module installed or reinstall it if necessary.
You can use the following command in your terminal or command prompt:
check if the module is installed and its version:
python -m whois --versionIf the whois module is not installed, you can install it using the following command:
pip install python-whoisIf the whois module is installed but outdated, you can update it using the following command:
pip install --upgrade python-whois- Check for typos and correct usage:
Double-check your code for any typos or incorrect usage of the whois.whois() method. Make sure you are using it correctly, as shown in the following example:
import whois
# Correct usage of whois.whois() method
w = whois.whois('example.com')- Use an alternative whois library:
If you are still encountering the error with the whois module, you can try using an alternative library, such as python-whois-extended or whois-parser. These libraries offer similar functionality and may work better for your use case.
pip install python-whois-extendedpip install whois-parserIn general, to avoid this Attributeerror: module ‘whois’ has no attribute ‘whois’, make sure you have the latest version of the whois module installed. Double-check your code for typos and usage errors, and verify that the module is compatible with your Python version and other dependencies.
Conclusion
In conclusion, this article Attributeerror: module ‘whois’ has no attribute ‘whois’, is an error message indicating that you are trying to access an attribute named “whois” in the “whois” module, but the attribute does not exist in the module.
By following the given solution, surely you can fix the error quickly and proceed to your coding project again.

Python AttributeError debugging checklist
- Print the actual type. Insert
print(type(obj))before the failing line — usually reveals the mismatch immediately. - Use dir().
print(dir(obj))lists all available attributes on the object. - Check version compatibility. Many AttributeErrors come from methods that were renamed or removed between library versions.
- Guard with hasattr().
if hasattr(obj, "method"): obj.method()— useful for cross-version code. - Use type hints + mypy. Static type checking catches most AttributeErrors before you run the code.
Common root causes across all AttributeError variants
- None return values. A function returned None when the caller expected an object.
- Version drift. Library API changed between versions.
- Variable overwrite. A local variable was reassigned with the wrong type (list → dict, str → int).
- Method vs attribute confusion. Calling a property with () or accessing a method without ().
- Missing initialization. Some frameworks require
init()before accessing certain attributes.
Modern Python tooling to prevent AttributeError
- Type hints + Optional[T]. Explicit null-handling in signatures.
- mypy or Pyright. Runs your codebase through a type checker before you run it.
- Ruff. Fast linter that catches many attribute-access issues.
- pydantic v2. Runtime validation with the same syntax as static types.
- pytest fixtures. Test with edge-case inputs to catch AttributeError paths early.

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.
