Python is a versatile programming language that has gained popularity in recent years due to its ease of use, scalability and object-oriented approach. However, like any other programming language, Python has its own set of errors that programmers may encounter. One such error is the ‘staticmethod’ object is not callable.
This error occurs when the programmer tries to call a static method using the parentheses ‘()’, which is the syntax used to call regular methods. Static methods are not associated with an instance of the class and can be called without creating an object of the class. Therefore, calling a static method using parentheses can result in the ‘staticmethod’ object is not callable error.
So, how can this error be resolved? The solution is quite simple – instead of using parentheses, the programmer should call the static method using the class name followed by the method name. This will ensure that the method is recognized as a static method and can be called without the need for an object of the class.
In conclusion, the ‘staticmethod’ object is not callable error is a common error that can be easily resolved by understanding the difference between regular methods and static methods in Python. By following the correct syntax while calling static methods, programmers can avoid this error and ensure that their code runs smoothly.

Introduction
Python is gaining popularity among developers due to its simplicity, readability, and flexibility. Python has a vast library of pre-installed modules that developers use to create applications, websites, and games. However, Python still faces challenges during coding, such as the ‘staticmethod’ object not callable error.
The meaning of ‘staticmethod’ error message
When you encounter this error message, it means that the method you are trying to call is a static method. You must take note that calling static methods require calling the class and not the instance. Calling the method via an instance would return the error message.
Sample code to recreate the ‘staticmethod’ error
Here is a simple code snippet that shows how you can create the ‘staticmethod’ object not callable error in your code:
class Example: @staticmethod def example_static_method(): print(This is a static method)example_instance = Example()example_instance.example_static_method()Solving ‘staticmethod’ object not callable error
If you follow through with above code execution, you would have noticed the error message: TypeError: ‘staticmethod’ object is not callable.
The following are the ways you solve the error message:
1. Call via class name
The best way to solve the issue is to call the method via the class name prefix, ignoring the instance variable.
class Example: @staticmethod def example_static_method(): print(This is a static method)Example.example_static_method()2. Use @classmethod instead of @staticmethod
If the function or method is designed to communicate with the class and its structure, use @classmethod instead of the @staticmethod decorator. The use of @classmethod would make the method call possible via class and instance.
class Example: @classmethod def example_class_method(cls): print(This is a class method)example_instance = Example()example_instance.example_class_method()Example.example_class_method()3. Use Python Version 3.7+
The ‘staticmethod’ object not callable error could also be because you are using Python version 3.6 or lower. The error is not an issue in Python version 3.7+ since the object’s staticmethod can be correctly called via the class instance. Here’s an example:
class Example: @staticmethod def example_static_method(): print(This is a static method)example_instance = Example()example_instance.example_static_method()Example.example_static_method()Comparison table of the solutions
| Solution | Description | Pros | Cons |
|---|---|---|---|
| Call via class name | Call the method via the class name prefix, ignoring the instance variable. | Easy to implement. | Requires sudden changes to your code, which might lead to confusion and errors. |
| Use @classmethod decorator | Use the @classmethod decorator if the method is designed to interact with the class structure. | This solution allows methods to be called via the class and the instance variables. | More complex than calling via class name as it requires modification of the function signature. |
| Use Python 3.7+ | Solution applicable for Python version 3.7 and above as staticmethod objects can be correctly called via the class instance. | Easy to implement and does not require any modification of code. | This solution would not work on Python versions 3.6 and below, making it less flexible. |
Conclusion
Python is an excellent programming language that appeals to developers due to its simplicity, flexibility, and its many libraries. During coding, the ‘staticmethod’ object not callable error could arise; this may be due to several reasons. In this article, we have discussed three main solutions to solve the error message: call via class name, use @classmethod instead of @staticmethod, and use Python version 3.7+. All solutions are useful depending on individual developer preferences and programming requirements. The comparison table provides an insight into the pros and cons of each solution, thereby allowing developers to make informed choices when addressing the ‘staticmethod’ object not callable error.
Thank you for reading our blog about how to solve the ‘staticmethod’ object is not callable error in Python. We hope that this article has helped you understand this common error and provided valuable insights on how to fix it.
Python is a popular programming language used by developers around the world, and while it offers many benefits, it can also be challenging at times. Learning how to troubleshoot errors like the ‘staticmethod’ object is not callable is essential for every Python developer, whether you’re a beginner or an expert.
If you encountered this error while working on your Python project, don’t worry! By following the steps outlined in this article, you can easily resolve the problem and continue working on your code with minimal disruption. Remember that Python has an extensive community of developers who are always willing to help, so don’t hesitate to reach out if you need assistance.
As a beginner in Python, you may encounter an error message that says staticmethod object is not callable. This error can be frustrating, especially if you don’t understand what it means or how to fix it. Here are some common questions people ask about this error:
-
What does the ‘staticmethod object is not callable’ error mean?
When you define a static method in Python, it creates an object that represents the method. If you try to call this object as if it were a function, you’ll get the ‘staticmethod object is not callable’ error. This error occurs when you forget to use the @staticmethod decorator or when you try to call the method incorrectly.
-
How do I fix the ‘staticmethod object is not callable’ error?
To fix this error, make sure you’re using the @staticmethod decorator when defining your method. You should also make sure you’re calling the method correctly, by using the class name instead of an instance of the class. For example:
- Correct: MyClass.my_static_method()
- Incorrect: my_instance.my_static_method()
-
Can I define static methods in a subclass?
Yes, you can define static methods in a subclass. However, if you want to call the static method from the superclass, you need to use the super() function to access it. For example:
class MySubclass(MyClass): @staticmethod def my_subclass_static_method(): return This is a subclass static method @staticmethod def call_super_static_method(): return super().my_static_method() -
What’s the difference between a static method and a class method?
A static method is a method that belongs to the class, but doesn’t have access to the instance or class itself. A class method, on the other hand, has access to the class itself as the first parameter, usually called ‘cls’. This means that a class method can modify the class or perform actions that affect all instances of the class. To define a class method, use the @classmethod decorator.
