Answer:
- def getCharacterForward(char, key):
- charList = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
-
- if(len(char) > 1):
- return None
- elif(not isinstance(key, int)):
- return -1
- else:
- index = charList.find(char)
- if(index + key <= 25):
- return charList[index + key]
- else:
- return charList[(index + key)% 26]
-
- print(getCharacterForward("C", 4))
- print(getCharacterForward("X", 4))
Explanation:
Firstly, define a charList that includes all uppercase alphabets (Line 2). We presume this program will only handle uppercase characters.
Follow the question requirement and define necessary input validation such as checking if the char is a single character (Line 4). We can do the validation by checking if the length of the char is more than 1, if so, this is not a single character and should return None (Line 5). Next, validate the key by using isinstance function to see if this is an integer. If this is not an integer return -1 (Line 6 - 7).
Otherwise, the program will proceed to find the index of char in the charList using find method (Line 9). Next, we can add the key to index and use the result value to get forwarded character from the charList and return it as output (Line 11).
However, we need to deal a situation that the char is found at close end of the charList and the forward key steps will be out of range of alphabet list. For example the char is X and the key is 4, the four steps forward will result in out of range error. To handle this situation, we can move the last two forward steps from the starting point of the charList. So X move forward 4 will become B. We can implement this logic by having index + key modulus by 26 (Line 13).
We can test the function will passing two sample set of arguments (Line 15 - 16) and we shall get the output as follows:
G
B

Answer:
You cannot do anything with the inspect element in reality for finding the answers on the College Board for the AP classes. The inspect classes are powerful tools that are hidden inside the browser. You are required to right-click on the web page, and you will then find the innards of that site, the complete source code, as well as the images and the CSS. as well as the icons that it makes use of. and much more. However, by the end of the day. and till morning, you will not be able to find the solution. For finding the answers on the College Board for AP classes. like here the AP world history, you need to understand World history. and for that, you need to read books and then you will come to know the keywords. And once you have the keyword, you can then find the answer to the questions based on those keywords. Hence, its the subject knowledge that matters, and not inspects element which is more of a developer's tool and not a researcher. You can use Search engine commands however as well. And you can post the questions here, and the whole community is here to help you and ensure you get through the AP classes that you deserve. And I will add, best of luck and you will achieve what you deserve.
