How can I effectively debug a Python script that’s raising an ‘AttributeError’ on a seemingly valid object attribute access? I’ve checked the object’s class definition and verified that the attribute exists, but I’m still encountering this error. What are some strategies or tools I can use to track down the root cause of this issue?

class MyClass:
    def __init__(self):
        self.data = []

    def add_item(self, item):
        self.data.append(item)

def main():
    obj = MyClass()
    obj.add_item("apple")
    obj.add_item("banana")

    for item in obj.items:
        print(item)

if __name__ == "__main__":
    main()

I tried to debug my code using the PyCharm Debugger but nothing seemed to work! I am really stuck with this problem pls help

>Solution :

class MyClass:
    def __init__(self):
        self.data = []

    def add_item(self, item):
        self.data.append(item)

def main():
    obj = MyClass()
    obj.add_item("apple")
    obj.add_item("banana")

    # Change 'obj.items' to 'obj.data'
    for item in obj.data:
        print(item)

if __name__ == "__main__":
    main()

Replace obj.items with obj.data in the loop to access the correct attribute and fix the AttributeError.
