Todo List Application This is a simple Todo List application implemented in Python using the Tkinter library. It allows users to add, remove, and mark tasks as completed or incomplete.

Features: Add Task: Users can input tasks into the entry field and click the "Add Task" button to add them to the list. Remove Task: Users can select a task from the list and click the "Remove Task" button to delete it from the list. Toggle Completed: Users can double-click on a task in the list to mark it as completed (or incomplete if already completed). Task List: The listbox displays all the tasks, and completed tasks are marked with a checkmark symbol (✓).

How to Use: Run the todo_list.py script. Enter a task in the entry field and click the "Add Task" button to add it to the list. Select a task from the list and click the "Remove Task" button to delete it. Double-click on a task in the list to toggle its completion status.
