Explanation of Solution
Event handler:
An event handler is a module is implemented in python
- If user need a program to execute an operation at that time a particular event occurs, user must create an event handler that reply at that time of event takes place.
- Event can be pressing the key or mouse operation by the user. To deal this type of operation is considered as event handlers.
- If the defined event occurs, then call the handler function with help of object of event...

What does the value of the top variable indicate in this ArrayStack implementation?
What will happen if we call pop on this stack? What value will be returned, and what changes will occur in the array and the top variable?
3. If we push the value "echo" onto the stack, where will it be stored in the array, and what will be the new value of top?
4. Explain why index 0 contains the string "alpha" even though top is currently 3.
5. What would the state of the stack look like (values in the array and value of top) after two consecutive pop 0 operations?
