Python To-Do List App for Beginners | Build & Save Tasks Using Lists & File Handling
Ready to build something practical and powerful with Python?
In this mini project, we’ll guide you step-by-step to build a simple To-Do List App in Python that stores your tasks—even after you close the program!
You'll use real-world programming concepts:
🔹 Python Lists
🔹 File Handling (Read/Write to .txt file)
🔹 Functions
🔹 Conditional Logic (if-else)
🔹 While Loops
By the end of this video, you'll have a functional command-line To-Do List you can improve and expand.
🧠 Concepts Covered:
Adding tasks ✅
Viewing tasks 📄
Removing tasks ❌
Saving to and reading from a text file 💾
Looping and menu-driven program flow 🔁

💻 Sample Code Snippet:
def load_tasks():
try:
with open("tasks.txt", "r") as f:
return f.read().splitlines()
except FileNotFoundError:
return []
def save_tasks(tasks):
with open("tasks.txt", "w") as f:
for task in tasks:
f.write(task + "\n")
def main():
tasks = load_tasks()
while True:
print("\n1. View Tasks\n2. Add Task\n3. Remove Task\n4. Exit")
choice = input("Choose an option: ")
if choice == "1":
print("\nYour Tasks:")
for i, task in enumerate(tasks):
print(f"{i + 1}. {task}")
elif choice == "2":
task = input("Enter new task: ")
tasks.append(task)
save_tasks(tasks)
elif choice == "3":
num = int(input("Enter task number to remove: ")) - 1
if 0 LESS= num LESS THAN len(tasks):
tasks.pop(num)
save_tasks(tasks)
elif choice == "4":
break
else:
print("Invalid option.")
main()
This project will combine everything we’ve learned — lists, loops, conditions, and file handling — into one useful little tool.
It's perfect for absolute beginners but powerful enough to spark ideas for your own personal projects.
