the system is always saying that key is not lowercased. i also tried key = key_value_tuple [0].lower() but its not working? if there are any errors please also point them out. happy to correct 
Your code so far

else:
dict_settings[key] = value

key, value = key_value_tuple2
key, value = key.lower(), value.lower()
if key in dict_settings2:
return f"Setting '{key}' updated to '{value}' successfully!"
else:
return f"Setting '{key}' does not exist! Cannot update a non-existing setting."
