Write a Python program that asks the user for quantity and takes some marks out of 100 as input. Valid marks are 0 to 100. However, due to user error, some marks may fall outside that range, say 101 or -5 (minus five). Print average of valid marks and percentage of invalid marks (Error Rate). Assume there is at least one valid mark and at least one invalid mark.

I'm trying to create a c program that will take in a ten-digit ISBN number and then check to see if the number is valid by calculating its weighted sum. This is the code that I have up to know, but I'm not sure what to do next. Can you give me some pointers?     DOCUMENTATION-------------This program will determine if an ISBN number is valid by calculating its weighted sum.********************************************************************/#include <stdio.h>#include <stdbool.h> #define ISBN_SIZE 10#define MOD_NUM 11 void printInstructions(void);void getIsbn(int isbnArray[]);void printIsbn(int isbnArray[]);int calculateWeightedSum(int isbnArray[]);bool isIsbnValid(weightedSum);void printGoodbye(void); int main(){int isbnArray[ISBN_SIZE] = {0}; printInstructions();getIsbn(isbnArray); printf("\n\nThe ISBN ");printIsbn(isbnArray); if(isIsbnValid(calculateWeightedSum(isbnArray))){printf(" is valid.");}else{printf(" is not valid.");} printGoodbye(); return 0;}…

Need urgent help with Python Decorator creation Never used python decorator before Answer the following questions in the Python decorator context. Your answers should be written in a Markdown file. The quality of answers matters!! What is higher-order function and how it is different from functor? What are First-class objects? What is the significance of functions being First-class objects? What are inner functions? What is the major benefit of inner functions and why is it important for decorator Why @ symbol is called syntactic sugar? What's the biggest advantage of using it when decorators are used? How would it help Python's weak OOP encapsulation of Class? (Hint: google "Python @Property decorator")
