Tell us what’s happening:

I am unable to pass the first test “You should create a dictionary called test_settings”. All other tests run fine. Please help me where I am wrong.

Your code so far

def add_setting(settings: dict, new_pair: tuple) -> str:

    if not isinstance(new_pair, tuple) or len(new_pair) != 2:
        return "Error: Input must be a tuple of (key, value)."

    key = str(new_pair[0]).lower()
    value = str(new_pair[1]).lower()

    if key in settings:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
    else:
        settings[key] = value
        return f"Setting '{key}' added with value '{value}' successfully!"


def update_setting(settings: dict, update_pair: tuple) -> str:

    if not isinstance(update_pair, tuple) or len(update_pair) != 2:
        return "Error: Input must be a tuple of (key, value)."

    key = str(update_pair[0]).lower()
    value = str(update_pair[1]).lower()

    if key in settings:
        settings[key] = value
        return f"Setting '{key}' updated to '{value}' successfully!"
    else:
        return f"Setting '{key}' does not exist! Cannot update a non-existing setting."


def delete_setting(settings: dict, key_to_delete: str) -> str:

    key = str(key_to_delete).lower()

    if key in settings:
        del settings[key]
        return f"Setting '{key}' deleted successfully!"
    else:
        return "Setting not found!"


def view_settings(settings: dict) -> str:

    if not settings:
        return "No settings available."
    
    output = "Current User Settings:"
    

    for key, value in settings.items():

        display_key = key.capitalize()
        output += f"\n{display_key}: {value}"
        
    return output+"\n"

test_settings = {
    'theme': 'dark', 
    'notifications': 'enabled', 
    'volume': 'high',
    
}



print("--- Initial State ---")
print(view_settings(test_settings))
print("-" * 25)


print("\n--- Test 1: Adding Initial Settings ---")
print(add_setting(test_settings, ('ThEmE', 'dArK')))
print(add_setting(test_settings, ('nOTIFICATIONS', 'eNaBLED')))
print(add_setting(test_settings, ('volume', 'High')))
print("\n[Current Settings]")
print(view_settings(test_settings))


print("\n--- Test 2: Attempting to Add Existing Key ---")
print(add_setting(test_settings, ('theme', 'light'))) # Should fail
print("\n[Current Settings]")
print(view_settings(test_settings)) # Should still be dark


print("\n--- Test 3: Updating Existing Key ---")
print(update_setting(test_settings, ('notifications', 'disabled')))
print(update_setting(test_settings, ('VOLUME', 'medium')))
print("\n[Current Settings]")
print(view_settings(test_settings))


print("\n--- Test 4: Attempting to Update Non-Existing Key ---")
print(update_setting(test_settings, ('language', 'spanish'))) 
print("\n[Current Settings]")
print(view_settings(test_settings))


print("\n--- Test 5: Deleting Keys ---")
print(delete_setting(test_settings, 'theme'))
print(delete_setting(test_settings, 'NOTIFICATIONS'))
print("\n[Current Settings]")
print(view_settings(test_settings))


print("\n--- Test 6: Attempting to Delete Non-Existing Key ---")
print(delete_setting(test_settings, 'theme')) 


print("\n--- Test 7: Viewing Empty Settings ---")

delete_setting(test_settings, 'volume')
print(view_settings(test_settings))
print("-" * 25)

Issue is that tests are run after all your code is executed. This means that the test_settings dictionary will be empty.

Either remove manual test from the end of code, or add more entries to the test_settings.
