📝 Python Console To-Do List App
Copy and paste this code into your Python editor or terminal to use:

📋 Python To-Do List (Console) with File Saving
This version will save your tasks to todo.txt and loads them when you restart the app:
import os
FILE_NAME = "todo.txt"
todo_list = []
def load_tasks():
if not os.path.exists(FILE_NAME):
return
with open(FILE_NAME, "r", encoding="utf-8") as file:
for line in file:
parts = line.strip().split("|")
if len(parts) == 2:
task, done = parts
todo_list.append({'task': task, 'done': done == "1"})
def save_tasks():
with open(FILE_NAME, "w", encoding="utf-8") as file:
for item in todo_list:
file.write(f"{item['task']}|{'1' if item['done'] else '0'}\n")
def show_menu():
print("\n📝 To-Do List Menu")
print("1. View Tasks")
print("2. Add Task")
print("3. Mark Task as Completed")
print("4. Delete Task")
print("5. Exit")
def view_tasks():
if not todo_list:
print("📭 No tasks in the list.")
else:
print("\nYour To-Do List:")
for idx, task in enumerate(todo_list, start=1):
status = "✅" if task['done'] else "❌"
print(f"{idx}. {task['task']} [{status}]")
def add_task():
task = input("✍️ Enter the task: ").strip()
if task:
todo_list.append({'task': task, 'done': False})
save_tasks()
print("✅ Task added!")
else:

def mark_completed():
view_tasks()
if todo_list:
try:

save_tasks()
print(f"🗑️ Deleted task: {removed['task']}")

📋 Python GUI To-Do List with File Saving
This app lets users manage tasks in a GUI with automatic file saving to todo.txt:

self.entry.pack(padx=10, pady=10, fill=tk.X)
self.add_button = tk.Button(root, text="➕ Add Task", font=("Arial", 12), bg="#4CAF50", fg="white", command=self.add_task)
self.add_button.pack(padx=10, pady=5, fill=tk.X)
