Tell us what’s happening:

Setting ‘theme’ already exists! Cannot add a new setting with this name.
Setting ‘volume’ already exists! Cannot add a new setting with this name.
Setting’theme’ added with value 'dark’successfully!
Setting not found!
Current User Settings:
‘Theme’:‘dark’
‘Notifications’:‘enabled’
‘Volume’:‘high’
but its still showing errors

Your code so far

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

    value=key_value[1].lower()
    if key in settings:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
    else:
         test_settings.update({key:value})
         return f"Setting '{key}' added with value '{value}' successfully!"
   

def update_setting(settings,key_value):
    key=key_value[0].lower()
    value=key_value[1].lower()
    if key in settings:
        test_settings.update({key:value})
        return f"Setting'{key}' added with value '{value}'successfully!"
    else:
        return f"Setting '{key}' does not exist! cannot update a '{key}':'{value}'non-existing setting."

def delete_setting(settings,key_value):  
    key=key_value[0].lower()
    if key in settings:



        del test_settings[key]
        return f"Setting '{key}' deleted successfully!."
    else:
        return f"Setting not found!"    
   

def view_settings(settings):
    str="Current User Settings:\n"
    if len(test_settings)==0:
        return "No settings available"
    else:    
        for kv in test_settings.items():

look here, don’t you think you are missing a space?

also notice that you have a settings parameter but you are making your functions work only for the test_settings dictionary

arti.patel09 · February 17, 2026, 10:42am

after change following is the coding:

test_settings={‘theme’:‘dark’,‘notification’:‘enabled’}

def add_setting(setting,key_value):

key=key_value\[0\].lower()

value=key_value\[1\].lower()

if key in setting:

    return f"Setting '{key}' already exists! Cannot add a new setting with this name."

else:

     test_settings.update({key:value})

     return f"Setting '{key}' added with value '{value}' successfully!"

def update_setting(settings,key_value):

key=key_value\[0\].lower()

value=key_value\[1\].lower()

if key in settings:

    test_settings.update({key:value})

    return f"Setting '{key}' updated to '{value}'successfully!"

else:

    return f"Setting '{key}' does not exist! cannot update a '{key}':'{value}'non-existing setting."

def delete_setting(setting,key_value):

key=key_value\[0\].lower()

if key in setting:

    del test_settings\[key\]

    return f"Setting '{key}' deleted successfully!."

else:

    return f"Setting not found!"

def view_settings(test_settings):

str="Current User Settings:\\n"

if len(test_settings)==0:

    return "No settings available"

else:    

    for kv in test_settings.items():

        key=kv\[0\].title()

        value=kv\[1\]

        str+=f"'{key}':'{value}'\\n"

return str

print(add_setting({‘theme’:‘light’},(‘THEME’,‘dark’)))

print(add_setting({‘theme’:‘light’},(‘Volume’,‘high’)))

print(update_setting({‘theme’: ‘light’}, (‘theme’, ‘dark’)))

print(delete_setting({‘theme’: ‘light’}, ‘theme’))

print(view_settings(test_settings))

output

etting ‘theme’ already exists! Cannot add a new setting with this name.
Setting ‘volume’ added with value ‘high’ successfully!
Setting ‘theme’ updated to 'dark’successfully!
Setting not found!
Current User Settings:
‘Theme’:‘dark’
‘Notification’:‘enabled’
‘Volume’:‘high’

still i get following errors

arti.patel09 · February 17, 2026, 12:18pm

tell me where i am wrong

ILM · February 17, 2026, 12:26pm

you still have functions that work only with thtest_settings dictionary, because you are not always using the function parameters

and then check your spacing

arti.patel09 · February 17, 2026, 12:28pm

def add_setting(setting,key_value):

key=key_value\[0\].lower()

value=key_value\[1\].lower()

if key in setting:

    return f"Setting '{key}' already exists! Cannot add a new setting with this name."

else:

     test_settings.update({key:value})

     return f"Setting '{key}' added with value '{value}' successfully!"

what is wrong ??

ILM · February 17, 2026, 12:31pm

you have post again your code in a format that is difficult to read

which part is not clear? you are using test_settings inside your functions, your functions are not reusable, so they fail the tests

arti.patel09 · February 17, 2026, 12:54pm

its showing errors to convert key and value to lower case , that i am already doing

test_settings={'theme':'dark','notification':'enabled'}

Please Tell us what’s happening in your own words.

Learning to describe problems is hard, but it is an important part of learning how to code.

convert key and value to lower case message is coming which already done in the code but still its showing same errors

test_settings={'theme':'light','notification':'enabled'}

def add_setting(settings,key_value):
    key=key_value[0].lower()
    value=key_value[1].lower()
    if key in settings:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
    else:
         test_settings.update({key:value})
         return f"Setting '{key}' added with value '{value}' successfully!"
 

def update_setting(settings,key_value):
    key=key_value[0].lower()
    value=key_value[1].lower()
    if key in settings:
        test_settings.update({key:value})
        return f"Setting'{key}' updated to '{value}'successfully!"
    else:
        return f"Setting '{key}' does not exist! cannot update a '{key}':'{value}'non-existing setting."

def delete_setting(settings,key_value):  
    key=key_value.lower()
    if key in settings:
        del settings[key]
        return f"Setting '{key}' deleted successfully!"
    else:
        return f"Setting '{key}' not found!"        

def view_settings(settings):
    str="Current User Settings:\n"
    if len(settings)==0:
        return "No settings available"
    else:    
        for kv in settings.items():
            key=kv[0].title()
            value=kv[1]
            str+=f"'{key}':'{value}'\n"
    return str 
print(add_setting({'theme': 'light'},('THEME','dark')))  
print(add_setting({'theme': 'light'},('Volume','high')))
print(update_setting({'theme': 'light'}, ('theme', 'dark')))
print(delete_setting({'theme': 'light'}, 'theme'))
print(view_settings(test_settings))

now its working on parameter settings only not on test_settings but still not done

pkdvalis · February 17, 2026, 1:40pm

Here are some debugging steps you can follow. Focus on one test at a time.

add_setting should convert the key to lowercase.

Are there any errors or messages in the console?
What is the requirement of test?
Check the related User Story and ensure it’s followed precisely.
What line of code implements this?
What is the result of the code and does it match the requirement? (Write the value of a variable to the console at that point in the code if needed.)

If this does not help you solve the problem, please reply with answers to these questions.

ILM · February 17, 2026, 1:41pm

you are still using test_settings a lot, until you stop it will not work

dhess · February 17, 2026, 1:51pm

is the dictionary you are passing to add_settings the same as test_settings? and yet, in your function, you are updating the global test_settings variable rather than the dictionary you passed in your function call. does that make sense? you are doing the same thing in your other functions, too.

isaacc265 · February 17, 2026, 3:49pm

**THE many problem is that you are using global variable ‘**test_settings’ **instead of function parameter ‘**settings’ .

My code below only focus logic but maybe may not pass the unit test because you didn’t include project info

So double check info or provide the whore info or the test which is failing

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.
