You are a teacher and you are correcting papers of your students who wrote an exam you just conducted. You are tasked with the following activities.

1. Failed Students

Create the function count_failed_students() that takes one parameter: student_marks. This function should count the number of students who have failed the subject, returning the count as an integer. We say that a student has failed if their mark is less than or equal to 40.

Note: Iterate through the student marks to find out your answer. ​ Result should be an int.

>>> count_failed_students(student_marks=[90,40,55,70,30]))
2

2. Top Marks

The Headmaster wants to find the group of top students. What qualifies student marks as top marks fluctuates, and you will need to find the student marks that are greater than or equal to the current threshold.

Create the function above_threshold() where student_marks and threshold are the two required parameters:

1. student_marks are a list of marks for each student
2. threshold is the top mark threshold. Marks greater than or equal to this number are considered "top marks" .

This function should return a list of all marks that are greater than or equal to a scoring threshold.

Note: If you find a mark which is less than the threshold, you should continue to evaluating the next mark.​

>>> above_threshold(student_marks=[90,40,55,70,30], 70)
[90, 70]

3. First K Students.

Create the function first_k_student_marks() with parameters student_marks and k

1. Student marks are a list of marks of each student
2. k is the number of students.

You need to return the first K number of student Marks. Once you reach K number of students, you should exit out of the loop.

>>> first_k_student_marks(student_marks=[90,80,100], k=1)
[90]

4. Full Marks

Create the function perfect_score() with parameter student_info. student_info is a dictionary containing the names and marks of the students {"Charles": 90, "Tony": 80}

Find if we have any students who scored "full marks"(100%)on the exam. If we don't find any "full marks" in student_info, we should return "No hundreds"

Return the first student who has scored full marks - 100.

>>> perfect_score(student_info={"Charles": 90, "Tony": 80, "Alex":100})
Alex
>>> perfect_score(student_info={"Charles": 90, "Tony": 80})
No hundreds
