I am facing a problem while working on a Python project where I attempt to access a method of a class instance, but I consistently receive an AttributeError. Below is a simplified representation of my code:

class MyClass:
    def my_method(self):
        print("Hello, World!")

obj = MyClass()
obj.my_method()

Upon executing this code, my anticipation is for it to display “Hello, World!” Nevertheless, I am confronted with the subsequent error message:

AttributeError: 'MyClass' object has no attribute 'my_method'

I have thoroughly reviewed my class and method definitions, and they seem to be accurate. I have also attempted to change the name of the method and the class, but the problem continues. I am uncertain as to why this error is happening, since the method is clearly specified within the class.

What I’ve Tried

Verified that the method name matches the one used in the class definition.
Renamed both the class and the method to ensure there are no naming conflicts.

Printed out the dir(obj) to inspect the available attributes and methods of the instance.

Despite all attempts, I am still encountering the AttributeError.

Expected Outcome

I anticipate that the my_method function will be invoked and will display “Hello, World!” on the console.

You can access a Python online compiler through my website: pythononlinecompiler.com.

I am seeking assistance in identifying the root cause of this AttributeError and finding a resolution. Any advice or recommendations would be highly valued.
