• Day 24: try_except_else_finally.py – Full try-except-else-finally usage.
• Day 25: list_comprehensions.py + dict_comprehensions.py + set_comprehensions.py – Comprehensions with examples.
• Day 26-27: file_organizer_bot.py – Apply file handling, loops, functions in a project.
• Day 28-29: terminal_habit_tracker.py – Apply OOP, file I/O, error handling in a project.
• Day 30: DSA Folder: arrays.py, linked_list.py, queues.py, stacks.py, searching_algorithms.py, sorting_algorithms.py, trees.py – Solve small problems using each data structure.

---

Tips for Success

1. Write 10–15 small programs per day to reinforce concepts.
2. Mix theory and coding exercises daily.
3. Complete the projects in the last 4 days for practical experience.
4. Review previous topics to strengthen retention.
