User Configuration Manager (Python)

This project is part of the freeCodeCamp Python Certification.

It implements a simple user configuration manager that allows adding, updating, deleting, and viewing settings stored in a dictionary.

📌 Features

• Add a new setting (key-value pair)
• Update an existing setting
• Delete a setting
• View all current settings

---

🛠️ Technologies

• Python 3

📖 User Stories

1. You should define a function named add_setting with two parameters representing a dictionary of settings and a tuple containing a key-value pair

2. add_setting function should:

   • Convert the key and value to lowercase.
   • If the key setting exists, return Setting '[key]' already exists! Cannot add a new setting with this name.
   • If the key setting doesn't exist, add the key-value pair to the given dictionary of settings and return Setting '[key]' added with value '[value]' successfully!.
   • The messages returned should have the key and value in lowercase.

3. You should define a function named update_setting with two parameters representing a dictionary of settings and a tuple containing a key-value pair.

4. update_setting function should:

   • Convert the key and value to lowercase.
   • If the key setting exists, update its value in the given dictionary of settings and return: Setting '[key]' updated to '[value]' successfully!
   • If the key setting doesn't exist, return Setting '[key]' does not exist! Cannot update a non-existing setting.
   • The messages returned should have the key and value in lowercase.

5. You should define a function named delete_setting with two parameters representing a dictionary of settings and a key.

6. delete_setting function should:

   • Convert the key passed to lowercase.
   • If the key setting exists, remove the key-value pair from the given dictionary of settings and return Setting '[key]' deleted successfully!
   • If the key setting does not exist, return Setting not found!
   • The messages returned should have the key in lowercase.

7. You should define a function named view_settings with one parameter representing a dictionary of settings.

8. view_settings function should:

   • Return No settings available. if the given dictionary of settings is empty.
   • If the dictionary contains any settings, return a string displaying the settings. The string should start with Current User Settings: followed by the key-value pairs, each on a new line and with the key capitalized. For example, view_settings({'theme': 'dark', 'notifications': 'enabled', 'volume': 'high'}) should return:

Current User Settings:
Theme: dark
Notifications: enabled
Volume: high

9. For testing the code, you should create a dictionary named test_settings to store some user configuration preferences.
