Tell us what’s happening:

I couldn’t get pass test 4 Here is my code:

test_settings = {“Name”: “Messi”,“Theme”:“light”, “Background”: “Messi”, “Notifications”: True,
“Volume”: “Low” }

def add_setting (settings , key_pair):
#my problem starts Here
m = test_settings
update = tuple(m.lower() if isinstance(m,str) else m for m in key_pair)

key = update [0]
value = update [1]


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

Your code so far




test_settings = {"Name": "Messi","Theme":"light", "Background": "Messi", "Notifications": True,
"Volume": "Low" }







def add_setting (settings , key_pair):
    #my problem starts Here
    m = test_settings
    update = tuple(m.lower() if isinstance(m,str) else m for m in key_pair)

    key = update [0]
    value = update [1]


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

    test_settings [str(key)] = value

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


def update_setting(update, new_pair):
    new_update = tuple(m.lower() if isinstance(m,str) else m for m in new_pair)
    if key in update:
        return "Setting '\{key}\' updated to '\{value}\'"
print(add_setting(test_settings,("r""Ronaldo")))
#Were the Delete happens
def delete_setting (setting, change):
    pass

def view_settings(setting):
    pass

Hi @Question_3 ,

  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

You are not passing a tuple as the second argument in your function call.

Happy coding!

3

Is the problem with my function or my print call?

Tell us what’s happening:

Here is my code and I am failing to get step 6 and 7 and the same time here is my code:

test_settings = {“Name”: “Messi”,“Theme”:“light”, “Background”: “Messi”, “Notifications”: True,
“Volume”: “Low” }

def add_setting (settings , key_pair):
#my problem starts Here
m = test_settings
update = tuple(m.lower() if isinstance(m,str) else m for m in key_pair)

key = update [0]
value = update [1]
settings[key] = value
test_settings [str(key)] = value
if key in m

Your code so far




test_settings = {"Name": "Messi","Theme":"light", "Background": "Messi", "Notifications": True,
"Volume": "Low" }







def add_setting (settings , key_pair):
    #my problem starts Here
    m = test_settings
    update = tuple(m.lower() if isinstance(m,str) else m for m in key_pair)

    key = update [0]
    value = update [1]
    settings[key] = value
    test_settings [str(key)] = value
    if key in m:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
        # step 7
    if not key in m:
        settings[key] = value
        return f"Setting '{key}' added with value '{value}' successfully!" 

def update_setting(update, new_pair):
    key, value = [item.lower() for item in key_value_pair]
    if key in update.keys():
        return "Setting '{key}' updated to '{value}'"
print(add_setting({'theme': 'light'}, ('volume', 'high')))
#Were the Delete happens
def delete_setting (setting, change):
    pass

def view_settings(setting):
    pass

The thing I notice is when I remove test_settings [str(key)] = value I pass step 7 but not step 6 and when I bring back test_settings[str(key)] I pass step 6 but not 7

It says that my code raised and error before any test could be run and I don’t know what that error is and I don’t see any error

9

How are you testing your functions? I don’t see a function call in your code.

And look for the error in your browser’s console, not the fCC console.

10

I don’t have an error that I can see. I only see a light bulb and below it it says: Your code raised an error before any tests could run. Please fix it and try again. I tested add_settings when I wrote this code: print(add_setting({‘theme’: ‘light’}, (‘volume’, ‘high’)))

11 



test_settings = {"Name": "Messi","Theme":"light", "Background": "Messi", "Notifications": True,
"Volume": "Low" }







def add_setting (settings , key_pair):
    #my problem starts Here
    m = test_settings
    
    
    key = key_pair [0]. lower()
    value = key_pair [1]. lower()

    test_settings [str(key)] = value
    if key in settings:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
        # step 7
        settings [key] = value
    else:
        settings [key] = value
        return f"Setting '{key}' added with value '{value}' successfully!" 

print(add_setting({'theme': 'light'}, ('volume', 'high')))


def update_setting(update, new_pair):

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

    if key in update:
        return "Setting '{key}' updated to '{value}'"
print(update_setting("He","He"))
#Were the Delete happens
def delete_setting (setting, change):
    pass

def view_settings(setting):
    pass

I think I fixed it but know it says for me to convert update_setting to lowercase which I am pretty sure I am doing

12

I have a question don’t you just have to type in . lower after a variable to convert it to lowercase?

13

lower() is a string method you can apply to a variable with a string value and, yes, that would convert that variable’s value to a lowercase string.

Python String lower() Method

14

I have another question when I did key= key_pair[0]. lower() it made it into lowercase but when I did key = new_pair [0]. lower() I didn’t pass the test of converting key to lowercase in the update function

15

That function is only returning something if the key is in update.

16

What is the difference between key = key_pair [0]. lower and key = new_pair[0]. lower()? I am basically using the same code putting it in a different function and modifying it.

17 
def add_setting (settings , key_pair):
    
    m = test_settings
    
    
    key = key_pair [0]. lower()
    value = key_pair [1]. lower()

    
    if key in settings:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
        # step 7
        settings [key] = value
    else:
        settings [key] = value
        return f"Setting '{key}' added with value '{value}' successfully!" 

print(add_setting({'theme': 'light'}, ('volume', 'high')))


def update_setting(update, new_pair):

    key = new_pair[0]. lower()
    value = new_pair [1]. lower()
    
    if key in update.keys():
        return f"Setting '{key}' updated to '{value}'successfully!"
print (update_setting({'theme': 'light'}, ('theme', 'dark')))
18 



test_settings = {
"Name": "Messi",
"Theme":"light", "Background":"Messi", 
"Notifications": "enabled",
"Volume": "Low" 
}







def add_setting (settings , key_pair):    


    key = key_pair [0]. lower()
    value = key_pair [1]. lower()

    
    if key in settings:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
        # step 7
        
    else:
        settings [key] = value    
        return f"Setting '{key}' added with value '{value}' successfully!" 

print(add_setting({'theme': 'light'}, ('volume', 'high')))


def update_setting(updates, new_pair):

    key = new_pair[0].lower()
    value = new_pair [1]. lower()
    
    if key in updates:
        updates[key] = value
        updates.update({key :  value})
        
        return f"Setting '{key}' updated to '{value}'successfully!"

    else:   
       return f"Setting '{key}' does not exist! Cannot update a non-existing setting."
    
print (update_setting({'theme': 'light'}, ('theme', 'dark')))



#Were the Delete happens
def delete_setting (setting, change):

    key = change[0].lower()
    
    if setting == {}:
        return "Settings not found"

    if key in setting:
        del setting [key]
        setting [key] = key
        return f"Setting '{key}' deleted successfully!"

    else:
        return "Setting not found"
    

print(delete_setting(test_settings,"h"))


def view_settings(setting):
    
    if setting == {}:
        return "No settings available."


    else:
        first = "Current User Settings:\n"
        for s in setting.items():
            key = s[0]. title()
            value = s[1]
            
        
            first += f"{key} : {value}\n"
        return first
        
            

print(view_settings({'theme': 'dark', 'notifications': 'enabled', 'volume': 'high'}))

My problem is that I am not passing test 13 and I think I have updated the key but it is still saying: update_setting({'theme': 'light'}, ('theme', 'dark')) should update an existing key and return the success message Setting 'theme' updated to 'dark' successfully!.

19

Look at the spacing in the message you are returning.

test_settings = {
"Name": "Messi",
"Theme":"light", "Background":"Messi", 
"Notifications": "enabled",
"Volume": "Low" 
}







def add_setting (settings , key_pair):    


    key = key_pair [0]. lower()
    value = key_pair [1]. lower()

    
    if key in settings:
        return f"Setting '{key}' already exists! Cannot add a new setting with this name."
        # step 7
        
    else:
        settings [key] = value    
        return f"Setting '{key}' added with value '{value}' successfully!" 

print(add_setting({'theme': 'light'}, ('volume', 'high')))


def update_setting(updates, new_pair):

    key = new_pair[0].lower()
    value = new_pair [1]. lower()
    
    if key in updates:
        updates[key] = value
        
        
        return f"Setting '{key}' updated to '{value}' successfully!"

    else:   
       return f"Setting '{key}' does not exist! Cannot update a non-existing setting."
    
print (update_setting({'theme': 'light'}, ('theme', 'dark')))



#Were the Delete happens
def delete_setting (setting, change):

    key = change[0].lower()
    #setting[key] = key

    

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

print(delete_setting({'theme': 'light'}, 'theme'))


def view_settings(setting):
    
    if setting == {}:
        return "No settings available."


    else:
        first = "Current User Settings:\n"
        for s in setting.items():
            key = s[0]. title()
            value = s[1]
            
        
            first += f"{key}: {value}\n"
        return first
        
            

print(view_settings({"theme": 'dark', 'notifications': 'enabled', 'volume': 'high'}))

Now I am having problems with test 18, 19,21.

18. delete_setting should convert the key to lowercase.

19. delete_setting({'theme': 'light'}, 'theme') should remove the existing key and return the success message Setting 'theme' deleted successfully!.

21. delete_setting should correctly remove the given key from the dictionary.

I am pretty sure I did all of the things I was suppose to do

21

What is the value of change[0]?

Is setting a list? What method should you use to delete a key/value pair from setting?

What is your code doing here?
