Answer to Question #297603 in Python for Michael

Question

 In a class test the teacher announces the marks (negative marking is allowed) of n (n>0) students. A student can achieve maximum 100 marks. Write a python function print_marks(*marks)  that takes number of students, marks of students and return the marks and check the marks are valid or not. If valid then it calls the recursive function rec_Sort(*marks) which returns the students marks as a comma-separated string with elements in ascending order. (You can use of built-in function max ()/min() to do this).

Answer 1

def print_marks(*marks):
    nums = []

    for mark in marks:
        if type(mark) == int and mark >= -100 and mark <= 100:
            nums.append(int(mark))
        else:
            print('Invalid Input')
            return None

    print(rec_sort(nums))

def rec_sort(nums):
    if len(nums) == 1:
        return nums[0]
    else:
        minNum = min(nums)
        nums.remove(minNum)
        return f"{minNum}, {rec_sort(nums)}"

print_marks(12, -3, 45, 0, 90, 37)
