New Python Program: Basic File Manipulation

Créez file_manipulation.py comme décrit dans l’issue, en commençant par examiner les opérations de menu requises et le workflow de database.txt. Exécutez le programme avec Python 3 et testez manuellement l’affichage, l’ajout, la mise à jour, la suppression, les entrées invalides, les fichiers manquants et les erreurs de fichier. La tâche est terminée lorsque chaque opération fonctionne et que les données mises à jour sont enregistrées après chaque opération.

Hello Python enthusiasts! Let's expand our repository with a Python program that demonstrates basic file manipulation operations. This beginner-friendly task involves reading from and writing to text files, allowing users to create, read, update, and delete entries in a simple database file. This task will showcase file handling, loops, and conditional statements in Python.

Tasks:

• Create a Python program that reads data from a text file (database.txt) if it exists.
• Allow users to view existing entries, add new entries, update existing entries, and delete entries.
• Implement user-friendly menus and prompts for each operation.
• Ensure the program handles errors gracefully, such as invalid file access or incorrect user inputs.
• Save the updated data back to the text file after each operation.

Guidelines:

• Use Python 3.x for the program.
• Utilize file handling functions (open, read, write, close) to manipulate the database file.
• Include comments in your code to explain the logic and functionality.
• Test the program thoroughly, including edge cases and error scenarios.

Example:

2. Add Entry
3. Update Entry
4. Delete Entry
5. Exit

Select an option: 2
Enter name: John Doe
Enter age: 30
