Question

The add() method resizes the array properly when items are added to the array.

In the arraybag.py file define the add() method in the ArrayBag class by completing the following:

  1. Check array memory and increase it if necessary

To test your program run the test() method in the testbag.py file.

Your program's output should look like the following:

[画像:### Educational Content: Implementing Dynamic Arrays in Python #### Instructions The `add()` method is designed to dynamically resize the array when new items are added. Follow these steps to implement the `add()` method in the `ArrayBag` class within the `arraybag.py` file: 1. **Check Array Capacity**: Ensure that there is enough memory and increase the array size if necessary. #### Testing the Implementation To test your implementation, execute the `test()` method in the `testbag.py` file. --- #### Code Overview ```python class ArrayBag(object): """An array-based bag implementation.""" # Class variable DEFAULT_CAPACITY = 10 # Constructor def __init__(self, sourceCollection=None): """Sets the initial state of self, which includes the contents of sourceCollection, if it's present.""" self.items = Array(ArrayBag.DEFAULT_CAPACITY) self.size = 0 if sourceCollection: for item in sourceCollection: self.add(item) ``` #### Explanation - **Class Definition**: The `ArrayBag` class is an implementation of a bag using arrays. - **DEFAULT_CAPACITY**: It is a class variable that sets the default size of the array to 10. - **Constructor (`__init__` method)**: - Initializes the `items` array with the default capacity. - Sets the initial size of the bag to 0. - If a `sourceCollection` is provided, it iterates through each item and adds it to the bag using the `add()` method. #### Terminal Execution The terminal snapshot shows the command used to run the Python script: ```bash sandbox $ python3 arraybag.py sandbox $ ``` This indicates the execution of the `arraybag.py` script in a Python 3 environment.]
